WHAT IS PLURIOL E 200?

PLURIOL E 200 is a commercially specified member of the polyethylene glycol series, positioned at the low-molecular-weight, liquid end of that family. The numeral 200 represents a nominal average molecular weight and does not indicate a concentration, a percentage of active ingredient, a degree of purity, or the molecular mass of every chain in the container.

PEGs are polyethers made up predominantly of ethylene oxide-derived units, with hydroxyl groups on both ends in the conventional linear, dihydroxy material. Low-molecular-weight PEG 200 is generally a pourable, nearly colorless, hygroscopic liquid, whereas many longer-chain PEGs become more viscous, waxy, or solid as their average molecular weight rises.

The current product listing identifies PLURIOL E 200 as a liquid, water-soluble, nonionic material intended for cleaning and care formulations. PLURIOL E 200 should be understood as a technical commercial grade; use in cosmetics, pharmaceuticals, foods, and highly regulated applications requires independent confirmation of the grade, applicable specifications, and permission for the intended use.

A distinction is necessary between PLURIOL E 200 and PLURIOL E 200 LS. The LS suffix identifies a separately specified low-salt variant, so numerical requirements or storage advice from an LS-only technical bulletin must not automatically be represented as specifications for the unsuffixed product.

CAS NUMBER, EC / EINECS NUMBER AND CHEMICAL IDENTIFICATION

The broad PEG identity is represented by CAS 25322-68-3 and EC 500-038-2 in recognized chemical-safety records. These identifiers apply to polyethylene glycol as a substance family and therefore do not uniquely identify PLURIOL E 200's chain-length distribution, proprietary quality specification, or the manufacturing lot.

For purchasing and technical evaluation, the combination of product name, supplier product reference, approximate average molecular weight, and batch traceability is more informative than a CAS number alone. The current product-finder listing uses product reference 30044100; that reference should still be reconfirmed against the supplier's transaction and documentation.

PEG 200 is not identical to ethylene glycol, diethylene glycol, propylene glycol, polypropylene glycol, or polyethylene glycol with average molecular weight 400 or 600. Although several of these materials share a glycol or ether-containing structure, different molecular sizes, terminal-group contents, toxicological profiles, viscosities, and approved uses prevent treating them as interchangeable chemicals.

CHEMICAL STRUCTURE AND MOLECULAR CHARACTERISTICS

General linear PEG structure: HO-(CH2-CH2-O)n-H. An idealized oligomer with n repeat units has a molecular mass of approximately 18.02 + 44.05n g/mol, so a nominal average molecular mass near 200 corresponds roughly to four oxyethylene repeat units on average; commercial PEG 200 nevertheless contains multiple chain lengths.

The oxygen atoms within the ether backbone accept hydrogen bonds from water and other suitable molecules. The two hydroxyl termini both donate and accept hydrogen bonds, creating strong polar interactions that help explain aqueous miscibility, low vapor pressure, affinity for moisture, and solvation of selected polar ingredients.

The hydroxyl termini are primary alcohol groups. They can participate in typical alcohol chemistry under controlled manufacturing conditions, including esterification and formation of certain ether or urethane structures, but this reactivity should not be confused with the behavior of an active catalyst or a detergent surfactant in a finished cleaner.

Because polyethylene glycol has a chain-length distribution, average molecular mass can be reported as number-average, weight-average, or another method-dependent mean. Hydroxyl value provides a practical indirect check on average chain length for a predominantly difunctional material, but an actual certificate of analysis is needed to establish the value for a particular production batch.

The theoretical hydroxyl number for an ideal dihydroxy PEG with number-average molecular weight exactly 200 is about 561 mg KOH/g, calculated as 112,200 divided by 200. This is a stoichiometric estimate, not a guaranteed PLURIOL E 200 specification and not a measured lot result.

PHYSICAL AND CHEMICAL PROPERTIES

Product form at 23 °C: Liquid; confirmed for PLURIOL E 200 in the published product range.
Chemical nature: Polyethylene glycol, technical grade; nominal average molecular mass approximately 200 g/mol.
Appearance: Low-molecular-weight PEG liquids are generally clear to nearly colorless and viscous; exact color acceptance criteria must be obtained for this grade.
Kinematic viscosity: Approximately 60 mm2/s at 20 °C, reported in the manufacturer's product overview for PLURIOL E 200. The table's general 75 °C viscosity heading contains an explicit 20 °C qualifier for this entry; do not omit that qualifier.
Dynamic viscosity: Not independently established for the unsuffixed grade under a specified temperature and method. Numerical conversion from kinematic viscosity would require density at the same temperature and should not be mistaken for an independently measured manufacturer specification.
Density: Not reliably established as an exact unsuffixed PLURIOL E 200 specification in the checked product sources. As context only, the international chemical safety card groups PEG 200-600 liquids at a representative relative density of about 1.13, without supplying a dedicated PLURIOL E 200 value.
Water solubility: Water-soluble; the current product description directly identifies this property, and the international safety card for PEG 200-600 describes very good solubility at 20 °C.
Typical physical state near room temperature: Fluid liquid, with lower viscosity than higher-molecular-weight PEG grades under comparable conditions.
Melting/freezing behavior: No single grade-specific melting point established; the international safety card lists a PEG 200 softening/freezing region of approximately -65 to -50 °C, with possible supercooling and method dependence.
Boiling behavior: An exact normal boiling point for this particular commercial oligomer distribution is not reliably established. The international safety card lists approximately 250 °C for its broad PEG 200-600 grouping; do not use this as a verified sharp boiling point for PLURIOL E 200.
Vapor pressure: Low for PEG liquids; the international safety card for PEG 200-600 lists less than 10 Pa at 20 °C as a family-level reference, not a batch-specific determination.
Flash point: Exact unsuffixed-grade value and method not confirmed. A separately identified PLURIOL E 200 LS technical bulletin reports 171 °C by Cleveland Open Cup; this may illustrate behavior of a related PEG 200 grade but is not an approved substitute for the target grade's current SDS.
Water uptake: Hygroscopic. The magnitude depends on humidity, temperature, time, container integrity, and grade; no universal equilibrium moisture value should be inferred.
Hydroxyl functionality: Nominally two hydroxyl ends per conventional linear PEG chain; chain distribution and impurities influence measured hydroxyl values.
pH: For a neat nonaqueous PEG, a conventional aqueous pH is not a meaningful intrinsic property. A 5% aqueous-solution specification of pH 4.5-7.5 is published for the different PLURIOL E 200 LS grade and must not be misrepresented as the unsuffixed grade's acceptance range.
Color, moisture, acidity, peroxide content, residual low-molecular-weight glycols, trace ions, and related quality parameters: Grade/batch dependent; obtain the applicable current specification and COA.
Surface tension, refractive index, exact water activity, specific heat, thermal conductivity, and solubility in individual organic solvents: Not established from an applicable product-specific technical document for this profile.

HOW DOES PLURIOL E 200 WORK AT THE MOLECULAR LEVEL?

PEG 200 operates mainly through solvation, hydrogen bonding, water compatibility, viscosity contribution, and moisture interaction. It should not be described as anionic or cationic, nor should its contribution be explained by electrical neutralization or micelle formation typical of formulated ionic surfactants.

In an aqueous formulation, its ether oxygens and terminal hydroxyls interact with water molecules, allowing PEG 200 to dissolve into the bulk liquid rather than creating a separate hydrocarbon-rich phase. At appropriate concentrations it can modify the solvent environment surrounding other ingredients; whether this increases another material's solubility must be established experimentally because the effect is substrate and formulation dependent.

Hygroscopicity means the liquid tends to absorb moisture from humid air. In a closed manufactured product this can contribute to moisture retention, but in storage it is also a potential quality-control issue because unintended water pickup alters composition and possibly processing behavior.

In some systems, PEG 200 changes viscosity, evaporation behavior, tack, spreadability, or lubricity through bulk-liquid properties rather than by acting as a specialized thickener. Its relatively small molecular size means these effects differ from the structuring, film-building, or wax-like behavior available from high-molecular-weight polyethylene glycols.

The molecule's two hydroxyl groups may also be valuable when PEG 200 is used as a chemical starting material. Those groups allow formation of PEG derivatives whose functional properties can be quite different from the original liquid; a derivative's claims and hazards cannot be assigned back to the unreacted PEG feedstock.

WHICH INDUSTRIES USE PLURIOL E 200?

Manufacturer information specifically supports cleaning and care applications, including laundry formulations, hard-surface cleaning, and commercial hygiene. These are the clearest product-specific end-use categories for the unsuffixed PLURIOL E 200 grade.

Wider polyethylene glycol technology includes industrial processing, specialty chemical synthesis, resins, inks, cellulose-based products, textiles, and lubricating systems. Those broader PEG uses establish technically plausible assessment areas but do not prove that every PLURIOL E 200 shipment is recommended, qualified, or approved for every application.

When screening a new sector, distinguish three questions: whether the PEG 200 chemical family is used in that industry, whether the target grade has the necessary technical attributes, and whether all safety and regulatory conditions for that exact finished product are met. A positive answer to one question does not establish the other two.

PLURIOL E 200 IN LAUNDRY AND DETERGENT FORMULATIONS

In laundry liquids, a low-molecular-weight, water-soluble polyethylene glycol may serve as a secondary formulation aid that influences moisture management, solvent balance, ingredient compatibility, and handling. The manufacturer's product description identifies laundry use and its solubilizing, humectant, and processing functions, but it does not establish PLURIOL E 200 as the principal cleaning surfactant.

Detergency comes primarily from the cleaning system as a whole: surfactant selection, builders, enzymes where relevant, soil type, temperature, wash time, and water hardness. PEG 200 should therefore be evaluated against performance objectives such as clarity, viscosity over temperature, storage stability, dispensing behavior, fabric compatibility, and residual feel rather than assigned a universal cleaning-efficiency number.

Attractive properties in one composition can become disadvantages in another. Because PEG 200 is hydrophilic and retains moisture, formulators should check drying behavior, residue, water balance, and packaging sensitivity in addition to solubility and appearance.

For concentrated laundry liquids, repeatability under hot/cold storage, freeze-thaw conditions, and dilution with local tap water is more useful than a single room-temperature appearance observation. The presence of electrolytes, fragrances, polymers, and hydrotropes may change compatibility, so bench testing must be performed on the complete formulation.

PLURIOL E 200 IN HARD-SURFACE AND INSTITUTIONAL CLEANING

Low-molecular-weight polyethylene glycol can support liquid handling and solvent design in formulated hard-surface products. Because the product is nonionic and soluble in water, it can be screened alongside common surfactant families and compatible water-soluble co-solvents where formulators need a manageable aqueous phase.

Hydrophilic PEG 200 should not be portrayed as a stand-alone degreaser for every hydrophobic soil. Removal of oily deposits still depends on surfactants, appropriate builders, mechanical action, substrate, pH, and, where needed, more suitable solvents.

For industrial and institutional cleaning, the performance criteria may include wipe marks, nonvolatile residue, drying time, foam generation, material compatibility, worker exposure, and wastewater considerations. PEG 200's role should be tested specifically because the optimum properties of a floor cleaner, glass cleaner, wash-bath additive, and equipment cleaner are not identical.

A low vapor pressure can be valuable when the objective is reducing evaporation from the bulk ingredient during storage and handling, but it may also increase retained residue on a surface. Describing PEG 200 as 'low volatility' is therefore more defensible than promising streak-free drying in every finished cleaner.

PLURIOL E 200 IN SOLUBILIZATION AND FORMULATION COMPATIBILITY

Solubilization refers to the ability of a surrounding medium to keep another substance in a stable dissolved state. PEG 200 has a strongly polar, hydrogen-bonding character and may help tune the solvation environment, but no single amount of PEG 200 can be assumed to dissolve every fragrance, dye, preservative, or organic active.

A useful formulation screening protocol measures clarity at formulation temperature, clarity after storage, clouding during dilution, viscosity, odor, color, and changes after exposure to heat and cold. Compatibility with the surfactant system should be evaluated in the presence of actual salts and functional additives, since testing only PEG 200 with pure water may conceal practical limitations.

Water solubility does not mean that every material soluble in PEG 200 will remain dissolved after water is added. Partitioning, hydrogen bonding, salting-out effects, and interactions with the other formulation components can cause precipitation, phase separation, or haze on dilution.

Where highly lipophilic substances must be incorporated, formulators may still need a suitable hydrotrope, emulsifier, solvent, or another delivery technology. PEG 200 should be regarded as one design variable in that decision, not a substitute for solubility measurement.

PLURIOL E 200 AS A HUMECTANT AND MOISTURE-MANAGEMENT INGREDIENT

A humectant interacts with water and may reduce moisture loss from a compatible formulation or substrate under specified conditions. PEG 200 contains multiple oxygen-rich, hydrogen-bonding groups, making a moisture-management role consistent with the manufacturer-stated humectant application.

The same tendency to attract water means packaging, headspace, transfer conditions, and warehouse humidity matter. If a process depends on tightly controlled water content, the received material and any open container may need moisture testing before use.

Humectancy should not be equated with a fixed clinical moisturizing benefit, and technical PLURIOL E 200 should not be promoted as an automatically approved skin ingredient. Cosmetic-grade qualification, impurities, finished-product safety assessment, and suitable INCI labeling are separate decisions.

In water-based coatings, inks, or adhesives, a humectant may influence open time or drying. Whether PEG 200 improves a particular material depends on the required balance between retained moisture and rapid final cure, and must be supported by appropriate performance testing.

PLURIOL E 200 IN CHEMICAL INTERMEDIATES AND RESIN DEVELOPMENT

The two hydroxyl groups of linear PEG 200 provide reactive sites for industrial chemistry. At a conceptual level, low-molecular-weight PEG can contribute flexible oxyethylene segments to ester and other derivative structures, with the final performance governed by reagent selection, reaction completeness, and molecular architecture.

A separately designated PLURIOL E 200 LS technical bulletin discusses PEG participation in resin systems, derivative synthesis, textile auxiliaries, and related manufacturing operations. That document supports the broader chemical potential of PEG 200 but must not be used as proof that the unsuffixed PLURIOL E 200 has the same impurity thresholds, accepted uses, or contractual specification.

For a polymer or resin route, hydroxyl value, average molecular weight, water content, acidity, and trace ionic contaminants may be more important than the neat liquid's visual appearance. Small shifts in hydroxyl equivalents change stoichiometry, while unexpected water can interfere with moisture-sensitive reactions.

Where the application is a reactive intermediate rather than a finished formulation ingredient, obtain a suitable grade specification and process safety analysis. The mere presence of primary hydroxyl groups is not an instruction to combine PEG 200 with reactive reagents without qualified engineering controls.

ADDITIONAL INDUSTRIAL APPLICATIONS AND THEIR LIMITATIONS

Research and industrial patent literature contain examples of PEG 200 used as a reference or component in selected abrasive carrier fluids. This shows the chemical family's process relevance but does not establish a universal cutting-fluid formulation or manufacturer recommendation for PLURIOL E 200 in every machining or semiconductor process.

Broader PEG chemistry is also used in pigment processing, textile auxiliaries, cellulose products, and ink formulations. In each case, the relevant function can be quite different: moisture regulation, liquid-phase compatibility, softening, limited lubrication, or precursor chemistry.

A water-soluble PEG may not be appropriate where very low moisture uptake, rapid evaporation, electrical insulation, anhydrous chemistry, or minimal residual hydrophilicity is essential. A successful product fit should be proven with final-process performance rather than extrapolated from the phrase 'polyethylene glycol.'

For equipment contact, evaluate elastomers, plastics, surface finishes, filter media, and other wetted components under the real formulation, temperature, and exposure duration. General compatibility of a neat PEG with one material is not enough to demonstrate compatibility of every concentrated cleaner or reactive blend.

COSMETIC, PHARMACEUTICAL, AND FOOD-RELATED GRADE DISTINCTIONS

PEG 200 as a chemical type is encountered in cosmetic ingredient references, and PEG-4 is an INCI designation associated with approximately 200-molecular-weight polyethylene glycol. Nevertheless, PLURIOL E 200 is described in the consulted manufacturer materials as a technical-grade product, so no cosmetic authorization, contaminant specification, or finished-product suitability should be inferred from the structural relationship alone.

A pharmaceutical grade requires its own recognized pharmacopoeial standard, suitable quality system, application-specific testing, and supply documentation. Use of the general synonym 'macrogol' does not certify this product as a pharmacopoeial macrogol grade or as suitable for oral, injectable, or medical applications.

Polyethylene glycol as a regulated food additive appears under E 1521 / INS 1521 in some regulatory frameworks. However, the European Union specifications for E 1521 describe an average molecular weight range of 380-9,000 Da and named grades beginning with PEG 400, so a nominal 200 g/mol technical-grade product must not be marketed as complying with E 1521 on that basis.

Even where a jurisdiction permits a particular polyethylene glycol food use, the exact grade, purity limits, permitted food category, use level, and evidence of conformity still matter. The existence of a CAS number, INCI name, or broad PEG family food listing is not equivalent to permission to use PLURIOL E 200 in food.

Likewise, the material's water solubility is not proof of biodegradability under every method or a blanket environmental label. Sustainability or biodegradability claims should quote the actual test protocol, product scope, and current applicable regulatory definition.

WHAT PROBLEMS CAN PLURIOL E 200 HELP ADDRESS?

Insufficient fluidity in a high-molecular-weight PEG system: A lower-molecular-weight PEG can be examined where handling at room temperature is important, provided final rheology and performance remain acceptable.
Difficulty integrating a hydrophilic auxiliary: PLURIOL E 200 can be assessed as part of the aqueous solvent system; this does not imply it will solubilize every hydrophobic or electrolyte-sensitive material.
Excess evaporation of a highly volatile solvent: A low-volatility glycol component may help adjust the overall evaporation profile, but it can leave more persistent residue and should be checked against drying and surface appearance.
Unstable water balance or moisture loss: The humectant character can be useful in selected formulas, while high humidity exposure during manufacturing or storage can conversely increase unintended water uptake.
Need for a nonionic co-ingredient: PEG 200 contributes no deliberately introduced ionic surfactant charge and may be attractive where ionic interactions are undesirable, although the complete commercial material may still have trace ionic impurities relevant to sensitive processes.
Need for hydroxyl-functional intermediates: End-group chemistry offers a route to industrial PEG derivatives, subject to suitable specifications, manufacturing controls, and process validation.

IMPORTANT CONSIDERATIONS WHEN USING PLURIOL E 200

Moisture uptake is a central quality issue. Sampling procedures, drum closures, exposed tank surfaces, and transfer operations should limit unnecessary ambient-humidity exposure when water content influences the finished specification.

Distinguish dynamic viscosity (mPa.s) from kinematic viscosity (mm2/s). The numbers are connected by density only when units and measurement temperature are treated consistently; product comparisons based on mixed viscosity types can be misleading.

Temperature matters for nearly every handling decision. Lower temperatures can increase viscosity, while higher temperatures change fluidity, evaporation, process safety margins, and potentially the condition of packaging or reactive co-ingredients.

Do not assume PEG 200 is a strongly foaming surfactant. Its nonionic molecular architecture does not by itself make it equivalent to a fatty alcohol ethoxylate detergent, and there is no verified product-specific foam-height figure for PLURIOL E 200 in the checked product sources.

Check hydrolysis-, oxidation-, acidity-, and heat-sensitive formulations individually. PEG behavior in a bottle at ambient temperature cannot establish stability during prolonged high-temperature industrial processing or in the presence of strongly reactive chemicals.

Purity and grade designation become especially important when optical clarity, low ionic background, residual contaminants, or strict biological-contact requirements control the application. Technical-grade material should not be silently substituted for a grade selected for a more demanding regulatory market.

FORMULATION DEVELOPMENT AND VALIDATION APPROACHES

Begin by defining why PEG 200 is included: water retention, solvent balance, processing, viscosity adjustment, or intermediate functionality. Select measurements that directly evaluate that objective rather than relying on broad labels such as 'stabilizer' or 'solvent.'

For cleaning formulations, a useful screening set includes initial clarity, centrifuge or phase-stability screening where appropriate, viscosity at several temperatures, diluted-use performance, rinsing behavior, foam profile, and compatibility with packaging. The full formula should be evaluated with actual raw-material grades rather than idealized laboratory reagents.

For pigment-, ink-, or coating-related studies, distinguish dispersion quality, storage viscosity, moisture retention, substrate wetting, dry-film integrity, and residual surface tack. PEG 200 can affect these properties in opposing directions, so the acceptable choice depends on a documented performance target.

For a chemical intermediate, analytical control may prioritize hydroxyl number, water, acidity, molecular-weight distribution, and impurity profile before downstream reaction development. Process parameters should be established by qualified chemists under an appropriate process risk assessment; no generic reaction recipe is supplied here.

No universal inclusion percentage, blending temperature, mixing sequence, or shelf-life extension can be assigned reliably from the available product-specific evidence. A formulation should be validated at realistic storage and operating conditions before scale-up or commercial claims.

SIMILAR PRODUCTS AND ALTERNATIVES

PEG 300 and PEG 400 are chemically related, generally more viscous liquids with higher average chain length. They may differ in hydroxyl equivalent content, processing response, water uptake, and low-temperature behavior; substitutions can change finished-product rheology and should be validated.

Higher-molecular-weight polyethylene glycols, such as PEG 600 and solid PEG grades, are alternatives when different physical consistency is desirable. A solid or waxy grade is not a direct drop-in replacement for fluid PEG 200 in a process designed for ambient-temperature pumping.

Glycerol and propylene glycol are often considered for hygroscopic or co-solvent roles, but their molecular structures, boiling and freezing behavior, viscosity, taste or odor implications, occupational requirements, and regulatory grades differ. A comparison should use the required application rather than treating any two humectants as chemically equivalent.

Diethylene glycol and ethylene glycol are distinct chemicals with important toxicological and regulatory differences. Similar names do not justify their use as substitutes, particularly in consumer, cosmetic, pharmaceutical, or food-adjacent contexts.

PLURIOL E 200 LS is a related but separately specified commercial grade. The suffix can be important for applications sensitive to residual sodium and potassium or other contaminants, and the purchasing specification should name the desired variant explicitly.

Polypropylene glycols have more hydrophobic oxypropylene units and different water compatibility. They may be appropriate for some lubrication or processing tasks, but their selection requires an independent solubility and performance assessment.

INITIAL FORMULATION APPROACHES FOR PLURIOL E 200

The following examples illustrate how PLURIOL E 200 can be assessed during laboratory formulation development. PLURIOL E 200 is a liquid polyethylene glycol with an average molecular weight of approximately 200 g/mol, commonly referred to as polyethylene glycol 200 or PEG 200. According to the manufacturer's product information, PLURIOL E 200 is a water-soluble, nonionic ingredient used as a solubilizer, humectant and processing aid in cleaning and industrial applications. PLURIOL E 200 is not the same type of ingredient as a primary detergent surfactant and should be evaluated for its supporting functions.

The following formulations are illustrative laboratory screening approaches, not validated commercial recipes, manufacturing instructions or final products with confirmed regulatory compliance. Unless specified otherwise, all percentages are by weight (% w/w). The purity and grade of PLURIOL E 200, the water quality, surfactant system, solids content, storage temperature and processing conditions may alter the results. Consult the current technical data sheet and safety data sheet of the actual supplied grade before proceeding.

Although PLURIOL E 200 is readily miscible with water, this does not guarantee that every fragrance, oily component or pigment will be fully solubilized by PLURIOL E 200. Evaluate transparency, compatibility, viscosity, residue, moisture behavior and storage stability. In each screening series below, PLURIOL E 200 is the principal variable, while the other ingredients and test conditions remain constant.

EXAMPLE 1: PLURIOL E 200 SOLUBILIZATION SCREENING IN A LIQUID LAUNDRY DETERGENT

Objective: Determine how PLURIOL E 200 influences concentrate clarity, viscosity, low-temperature stability and dilution behavior in a water-based liquid laundry detergent.

Initial screening composition (finished laboratory test formulation, % w/w):

PLURIOL E 200: approximately 1.00%, 3.00% and 5.00% in separate trials.

Sodium laureth sulfate (SLES) aqueous solution, approximately 70% active: approximately 5.00% as supplied, held constant.

Compatible nonionic alcohol ethoxylate surfactant: approximately 2.00% as supplied, held constant.

Sodium citrate dihydrate: approximately 1.50%, held constant.

Sodium gluconate: approximately 0.30%, held constant.

Sodium xylene sulfonate solution or another suitable hydrotrope: approximately 2.00% as supplied, held constant.

Demineralized water: quantity sufficient to 100%.

Mixing temperature, stirring speed, surfactant grade, water hardness and storage-test conditions: held constant.

These concentrations are preliminary comparison levels, not a validated detergent formula. PLURIOL E 200 may influence viscosity and phase appearance differently at different electrolyte concentrations; no automatic improvement in clarity or cleaning power should be assumed.

Application approach:

1. Charge a clean mixing vessel with most of the demineralized water and begin moderate agitation.

2. Dissolve sodium citrate and sodium gluconate, then add the hydrotrope with sufficient mixing.

3. Incorporate the SLES solution gradually, followed by the fixed nonionic surfactant amount, while minimizing aeration.

4. Add PLURIOL E 200 at the designated screening concentration and complete each batch with water to 100%.

5. Measure pH, initial appearance, viscosity and foam; document any cloudiness or incompatibility.

6. Store equal samples under controlled ambient, cool and elevated-temperature conditions, then inspect for phase separation, precipitation and viscosity change.

7. Dilute the concentrates at a fixed ratio into waters of different hardness and compare clarity, dispersibility and any residue or gel formation.

8. Select the PLURIOL E 200 level that provides the most suitable formulation stability and handling, then confirm detergent cleaning performance separately.

Use suitable eye and skin protection when handling concentrated surfactants. Assess microbial preservation, package compatibility, labeling, wastewater behavior and relevant detergent regulations before scaling up; PLURIOL E 200 is not a substitute for a required preservative system.

EXAMPLE 2: PLURIOL E 200 LEVEL EVALUATION IN A HARD-SURFACE CLEANING LIQUID

Objective: Examine whether PLURIOL E 200 improves solvent balance, formulation uniformity and application behavior in a mildly alkaline hard-surface cleaner while avoiding excess film or slow drying.

Initial screening composition (finished laboratory test formulation, % w/w):

PLURIOL E 200: approximately 0.50%, 1.50% and 3.00% in separate trials.

Compatible low-foaming nonionic surfactant: approximately 0.50% as supplied, held constant.

Dipropylene glycol methyl ether (DPM) or a technically suitable water-miscible solvent: approximately 2.00%, held constant.

Sodium citrate: approximately 0.20%, held constant.

Sodium cumene sulfonate solution or another appropriate hydrotrope: approximately 0.80% as supplied, held constant.

Demineralized water: quantity sufficient to 100%.

Initial target pH: approximately 7.5–9.0, subject to ingredient and surface compatibility.

Test substrate, applied quantity, soil loading, dwell time, wipe material and drying temperature: held constant.

Because PLURIOL E 200 is relatively nonvolatile compared with water, excessive use may increase surface residue or drying time. The objective is to compare PLURIOL E 200 levels, not to claim universally streak-free performance.

Application approach:

1. Add most of the demineralized water to a clean laboratory mixing vessel at ambient temperature.

2. Dissolve sodium citrate under moderate agitation and add the selected hydrotrope.

3. Blend in the fixed amount of compatible nonionic surfactant and the water-miscible solvent.

4. Add PLURIOL E 200 slowly at the selected screening level and top up the formulation with water to 100%.

5. Measure pH, clarity, viscosity and stability after standing and at relevant storage temperatures.

6. Apply equal amounts of the PLURIOL E 200 test cleaners to standardized glass, glazed ceramic and compatible coated panels carrying a controlled greasy-fingerprint soil.

7. Compare soil removal, wipeability, foam, wetting, visible streaks, tackiness, residual film and drying time.

8. Identify the PLURIOL E 200 level that provides acceptable cleaning and handling with minimal residue, and verify performance under realistic conditions.

Assess every substrate before use, especially sensitive coatings, plastics and painted finishes. Wear protection appropriate to the solvent and surfactant system, control spray mist and validate all occupational, environmental and labeling requirements. This example is a cleaner and not a demonstrated disinfectant.

EXAMPLE 3: PLURIOL E 200 PROCESSING-AID SCREENING IN A WATER-BASED PIGMENT DISPERSION

Objective: Investigate how PLURIOL E 200 affects wet-milling behavior, dispersion viscosity, pigment settling and short-term storage stability in a model aqueous iron-oxide pigment concentrate.

Initial screening composition (laboratory pigment dispersion, % w/w):

PLURIOL E 200: approximately 0.50%, 2.00% and 4.00% in separate trials.

Synthetic iron-oxide pigment: approximately 20.00%, held constant.

Sodium polyacrylate dispersant solution or another pigment-compatible dispersant: approximately 2.00% as supplied, held constant.

Compatible nonionic wetting agent: approximately 0.30% as supplied, held constant.

Suitable aqueous defoamer: approximately 0.20% as supplied, held constant.

Demineralized water: quantity sufficient to 100%.

Pigment grade, dispersant grade, mixing energy, milling duration, temperature and storage container: held constant.

This is a model industrial dispersion rather than a ready-to-use paint, ink or coating. PLURIOL E 200 is screened as a co-solvent and processing aid, not assumed to replace the dedicated polymeric pigment dispersant. Pigment and additive compatibility must be demonstrated by laboratory testing.

Application approach:

1. Add most of the demineralized water to a suitable laboratory dispersing vessel equipped with controlled agitation.

2. Introduce the polyacrylate dispersant solution, the wetting agent and the chosen PLURIOL E 200 screening amount.

3. Slowly add the iron-oxide pigment under controlled mixing and appropriate dust collection to avoid airborne powder.

4. Increase mixing or milling energy within the equipment's safe limits and maintain the same processing duration for all samples.

5. Add the fixed defoamer level, adjust to final mass with water and mix until the dispersion is uniform.

6. Record processing behavior, temperature rise, viscosity, visible agglomerates and pigment fineness using suitable laboratory methods.

7. Store sealed samples under identical conditions and compare sedimentation, redispersibility, color strength, odor and short-term viscosity change.

8. Select the PLURIOL E 200 level with the best balance of processing efficiency and dispersion stability, then test compatibility with any intended final binder system.

Avoid inhalation of pigment dust and exposure to high-speed mixing equipment. Use appropriate local exhaust ventilation, eye and hand protection and equipment safeguards. Verify the current safety data sheets, microbial preservation needs, waste handling and the regulatory requirements of the intended coating or industrial application.

QUALITY CONTROL AND PURCHASING CRITERIA

Confirm the exact trade name, suffix, manufacturer product code, nominal average molecular weight, packaging, and intended application. A purchase order naming only 'PEG' is insufficient because the chemical family spans low-viscosity liquids, waxes, and solids with widely differing specifications.

Review the current technical data sheet (TDS) for representative properties and stated test methods. A TDS explains product positioning but typically does not replace the batch release limits or establish regulatory approval for a specific end use.

Review the safety data sheet (SDS) for the destination jurisdiction and current grade. The SDS governs hazard communication, handling, first aid, storage, spill response, and transport decisions; an older SDS for another PEG grade is not an adequate substitute.

Request a certificate of analysis (COA) or agreed batch certificate where appropriate. Depending on application and available manufacturer controls, relevant parameters may include appearance, color, moisture, hydroxyl value, acidity, specified ions, residual low-molecular-weight species, and trace contaminants.

Check how the molecular-weight estimate is obtained. An apparent 200 g/mol grade designation need not correspond to a single measured molecule or to a sharp molecular-weight cut-off, and test methods can influence comparisons between suppliers.

Confirm whether sample history and packaging could have altered water content. A tightly closed original container and an open laboratory bottle can exhibit different measured values because polyethylene glycol takes up atmospheric moisture.

For critical formulations, evaluate small representative production lots against the actual process rather than relying solely on a generic PEG 200 reference. A scientifically defensible specification links analytical quality to the output requirement.

FIRST AID

Inhalation: If PLURIOL E 200 mist, heated vapor, or aerosol is inhaled and discomfort occurs, move the person to fresh air and keep them at rest. Seek medical assessment for persistent coughing, breathing difficulty, or other concerning symptoms; the airborne exposure scenario depends on whether the liquid has been heated or sprayed.
Skin Contact: Remove contaminated clothing and wash skin exposed to PLURIOL E 200 thoroughly with water and mild soap. Obtain medical attention if irritation persists, and address slip hazards from contamination on floors or footwear.
Eye Contact: Flush eyes exposed to PLURIOL E 200 promptly with gently flowing water for several minutes, removing contact lenses when easy to do. Continue rinsing and obtain medical advice if irritation persists or significant exposure occurred; follow the current safety data sheet for the exact grade.
Ingestion: Rinse the mouth after accidental ingestion of PLURIOL E 200, do not induce vomiting, and obtain advice from a poison center or medical professional when a meaningful amount has been swallowed or symptoms develop. The polyethylene glycol safety card identifies nausea and diarrhea as possible ingestion effects; industrial grade material must not be treated as an ingestible product.
Note to Physicians: Manage exposure to PLURIOL E 200 according to symptoms, route, quantity, and the current product SDS. No chemical-specific antidote or unverified home neutralization procedure is proposed here.

HANDLING AND STORAGE

Handling: Use PLURIOL E 200 in clean, suitable vessels and minimize prolonged open exposure because it is hygroscopic. Prevent splashes, minimize aerosol formation during pumping or spraying, and immediately control spills that create very slippery surfaces.
Engineering Controls: Provide ventilation appropriate to PLURIOL E 200 handling and additional local control if warm processing generates mist. For routine closed transfer at ambient temperature, airborne release is often limited, but the site-specific exposure assessment remains decisive.
Personal Protection: Wear safety eyewear and suitable chemical-resistant gloves when transferring or sampling PLURIOL E 200. Choose glove materials and replacement intervals using the current regional SDS and the actual contact conditions rather than generic assumptions.
Respiratory Protection: Ordinary sealed-liquid operations may not require respiratory protection, but PLURIOL E 200 mist or aerosol exposure may call for appropriate controls and respiratory equipment selected by a competent safety professional.
Storage: Keep PLURIOL E 200 containers dry, tightly closed, and protected from contamination and unnecessary heating. Warehouse temperature limits and storage duration should come from the current grade-specific supplier documentation; do not apply the limits in a different LS-grade bulletin automatically.
Packaging and Materials: Select storage vessels and transfer lines for PLURIOL E 200 on the basis of verified compatibility, cleanliness, and the intended period of contact. A bulletin for the separate LS grade warns of iron pickup and discoloration from mild steel, illustrating why material compatibility can matter, but it is not a binding specification for the unsuffixed grade.
Spill Procedures: Contain PLURIOL E 200 liquid, prevent entry to drains when required, and collect using suitable absorbent or mechanical recovery. Clean the floor thoroughly after bulk removal because remaining PEG liquid mixed with water may still be slippery.
Environmental Precautions: Avoid uncontrolled releases of PLURIOL E 200 to waterways and process effluent systems. Confirm the relevant wastewater and waste-treatment rules, and do not assume that water solubility removes the need for environmental controls.
Fire Response: PEG 200 is a combustible organic liquid at sufficiently elevated temperatures and can contribute fuel to a fire. Use extinguishing media appropriate to the surrounding fire and the current SDS; avoid treating a relatively high flash point as proof that overheating is harmless.
Waste Disposal: Dispose of PLURIOL E 200 residues, absorbents, and contaminated packaging according to local requirements and site waste characterization. Recycling, recovery, or discharge decisions depend on contamination and applicable regulations, not only the PEG chemical name.

SAFETY AND TRANSPORT INFORMATION

The international chemical safety card for PEG 200-600 describes a combustible, viscous liquid and recommends eye protection, ventilation where appropriate, and dry, tightly closed storage. Because that card covers several PEG grades, its physical property ranges and first-aid notes should be used as family-level context rather than a substitute for the current PLURIOL E 200 SDS.

For normal bulk handling, likely practical risks include contamination, eye exposure, slippery floors, and mist inhalation during high-energy or heated operations. Elevated process temperatures increase the importance of fire control and equipment management even when an ambient-temperature liquid is not treated like a highly volatile solvent.

Transport classification: A grade-specific UN number, proper shipping name, hazard class, and packing group were not verified from a current, publicly accessible PLURIOL E 200 SDS in the source set reviewed. Therefore no universal UN classification is stated here; transport documents must be prepared from the exact shipment's current regional SDS and applicable ADR, RID, IMDG, or IATA rules.

Regulatory status is not identical to product approval. CAS and EC identifiers establish chemical identification, while approvals or exemptions for cosmetics, food contact, pharmaceuticals, and other regulated uses require their own jurisdiction-specific evidence.

For safe purchasing, request the current SDS, confirm that it names PLURIOL E 200 rather than PLURIOL E 200 LS or a different molecular-weight PEG, and reconcile any regional differences in hazard or transport statements before shipment.

What is the manufacturer product reference?
The current published product listing identifies PLURIOL E 200 with product number 30044100; buyers should confirm this against current order documents.

Is PLURIOL E 200 a single molecule?
No. The material contains a distribution of short PEG chains centered on a stated average molecular mass.

What is the general molecular formula of PLURIOL E 200?
The appropriate general structure is HO-(CH2-CH2-O)n-H, where n varies across chains; there is no one fixed molecular formula for the commercial PEG distribution.

How many hydroxyl groups are present?
Conventional linear PEG molecules have two terminal hydroxyl groups, although analytical results for the commercial grade depend on distribution and impurities.

What is the expected hydroxyl value?
An ideal difunctional PEG at exactly 200 g/mol has a calculated hydroxyl number of about 561 mg KOH/g, but this is not a measured or guaranteed PLURIOL E 200 specification.

What does nonionic mean for this product?
The PEG backbone does not contain intentionally ionized surfactant head groups; trace ionic impurities are a separate grade-quality consideration.

Is PLURIOL E 200 liquid at room temperature?
Yes. The published manufacturer guide describes it as liquid at approximately 23 °C.

What is PLURIOL E 200's viscosity at 20 °C?
The manufacturer product range reports approximately 60 mm2/s at 20 °C as kinematic viscosity; this is not a dynamic viscosity value in mPa.s.

Can 60 mm2/s be called 60 cP?
No. Conversion between kinematic viscosity and dynamic viscosity requires density at the same temperature, so these units are not automatically interchangeable.

What is the density of PLURIOL E 200?
An exact current density specification was not verified for the unsuffixed grade; the broader PEG 200-600 safety card describes a representative relative density near 1.13.

Is PLURIOL E 200 soluble in water?
Yes. The manufacturer identifies PLURIOL E 200 as water-soluble, consistent with the strong hydration of its ether and hydroxyl groups.

Will PEG 200 dissolve every fragrance or oil?
No. Solubility depends on the particular ingredient and the complete formulation; water miscibility of PEG 200 does not guarantee oil solubilization.

Does PLURIOL E 200 have a measured cloud point?
No verified grade-specific cloud point was identified in the consulted documents; do not transfer cloud point values from alcohol alkoxylate surfactants.

What is the boiling point of PLURIOL E 200?
A precise normal boiling point was not confirmed for the commercial grade; a PEG 200-600 safety card lists approximately 250 °C as broad-range reference information.

What is the freezing point of PLURIOL E 200?
A family-level safety card cites roughly -65 to -50 °C for PEG 200, with supercooling and method differences; confirm any low-temperature operating requirement separately.

What is the flash point of PLURIOL E 200?
A separate LS-grade bulletin gives 171 °C by Cleveland Open Cup, but the exact PLURIOL E 200 flash point must be taken from its current SDS or technical documentation.

Is PLURIOL E 200 flammable?
It is an organic combustible liquid at elevated temperatures; do not infer a specific regulatory flammable-liquid category without the exact grade SDS.

Does PLURIOL E 200 evaporate quickly?
PEG 200 has comparatively low volatility, but evaporation and residue in a formulated product depend on the other ingredients and temperature.

Is PLURIOL E 200 hygroscopic?
Yes. It can absorb moisture from air, which may affect water content during handling and storage.

Can PLURIOL E 200 function as a humectant?
Yes. Its polar ether groups and hydroxyl termini interact with water, and humectancy is one of the functions in the product description.

Is PLURIOL E 200 a detergent surfactant?
Not in the same sense as a conventional fatty alcohol ethoxylate cleaning surfactant; PLURIOL E 200 is presented primarily as a solubilizer, humectant, and processing aid.

Does PLURIOL E 200 generate foam?
No verified product-specific foam height or foaming classification was found, so a numerical foam claim should not be made.

Can PLURIOL E 200 improve laundry liquids?
It can be evaluated for solvent balance, ingredient compatibility, water retention, and processing, but the cleaning and rinse results must be demonstrated in the finished formula.

Can PLURIOL E 200 be used in hard-surface cleaners?

Is PLURIOL E 200 appropriate for institutional cleaning?
Commercial hygiene is listed as a use area, subject to appropriate grade selection and validation for the intended system.

Can PLURIOL E 200 serve as a co-solvent?
Its water-compatible, hydrogen-bonding character supports co-solvent screening, but actual solubilization depends on solute chemistry and composition.

Is PLURIOL E 200 a hydrotrope?
It is best described from the checked sources as a water-soluble solubilizing and processing aid; a formal hydrotropic performance claim requires formula-specific evidence.

Can PLURIOL E 200 function as an antifreeze?
Low-molecular-weight PEG has a low freezing region, but no approved or universal antifreeze formulation or freezing-point-depression performance claim is established for this grade.

Can PLURIOL E 200 control drying time?
It may change the moisture and volatility balance in some formulas, but faster or slower drying depends on the complete composition and substrate.

Can PLURIOL E 200 be used in inks?
PEG chemistry is known in certain ink-processing applications; use of the specific unsuffixed grade requires application and compatibility validation.

Can PLURIOL E 200 be used in coatings?
It may be evaluated as a hydrophilic auxiliary or intermediate in selected coatings, but finished film properties and residual water sensitivity must be verified.

Can PLURIOL E 200 be used in resin synthesis?
Its two hydroxyl groups make it chemically useful as a PEG-based intermediate, while the required grade and process details must be established by qualified manufacturers.

Can PLURIOL E 200 be used in textile processing?
PEG 200 chemistry has potential as a moisture-management or process auxiliary, but the unsuffixed grade must be evaluated for the specific textile process.

Is PLURIOL E 200 suitable for cosmetics?
The PEG 200 chemical family can correspond to INCI PEG-4, but technical PLURIOL E 200 is not automatically a cosmetic-qualified ingredient.

What is the INCI name for nominal PEG 200?
PEG-4 is a commonly associated INCI designation for approximately 200-molecular-weight polyethylene glycol; confirm the precise INCI and compliance with the cosmetic-grade supplier.

Is PLURIOL E 200 pharmaceutical grade?
No such grade qualification was established; the generic synonym macrogol does not create a pharmacopoeial certification.

Can PLURIOL E 200 be used as a food additive?
Do not assume so. EU E 1521 PEG specifications cover an average molecular-weight range starting at 380 Da, which excludes nominal PEG 200.

Is the E number 1521 applicable to PLURIOL E 200?
Not as a demonstrated certification of this technical grade. E 1521 is a regulated PEG family entry with its own molecular-weight and purity specifications.

Is an INS number the same as food approval?
No. INS 1521 identifies a food-additive category, while permission to use a specific grade depends on jurisdiction, specification, and permitted food categories.

Is PLURIOL E 200 biodegradable?
Product-family listings may contain biodegradability classifications, but any specific advertising claim should match the exact tested material and method.

Is PLURIOL E 200 the same as PLURIOL E 200 LS?
No. The LS designation is a distinct product specification and should not be removed from technical or purchasing comparisons.

What distinguishes PEG 200 from PEG 400?
PEG 400 has a higher average molecular weight and typically different viscosity, hydroxyl number, low-temperature behavior, and handling properties.

Can glycerol replace PEG 200?
Potentially for selected humectant or solvent functions, but their viscosity, water behavior, and chemical structures differ, so reformulation and performance testing are required.

Can propylene glycol replace PLURIOL E 200?
Propylene glycol is a distinct low-molecular-weight diol; substitution must be justified by technical performance, grade, safety, and regulatory requirements.

Is ethylene glycol equivalent to PEG 200?
No. They are chemically distinct substances with different properties and safety considerations and should never be treated as interchangeable solely because of their names.

Is the molecular weight a quality-control parameter?
Yes. Average molecular weight and distribution can affect hydroxyl functionality, viscosity, and application performance, but the accepted analytical method should be specified.

Why is hydroxyl number important?
It estimates the concentration of hydroxyl end groups and can help characterize PEG chain length or determine the equivalent input for downstream reactions.

What is the most important moisture-related risk?
Absorption of atmospheric water during open storage or transfer can change material composition and interfere with moisture-sensitive manufacturing.

How should PLURIOL E 200 be stored?
Keep it sealed, dry, and protected from contamination or needless heating; use grade-specific instructions for permitted temperature and storage life.

Does PLURIOL E 200 have a guaranteed two-year shelf life?
No generic shelf life was confirmed for unsuffixed PLURIOL E 200. A separate LS-grade bulletin discusses a two-year certificate endorsement under specified conditions, which must not be transferred automatically.

Can PLURIOL E 200 be stored in steel tanks?
Confirm equipment compatibility with the specific grade. The separate LS technical bulletin warns about discoloration from prolonged mild-steel contact, so material selection should be evaluated.

Are eye protection and gloves needed?
Appropriate protective eyewear and chemically suitable gloves are prudent during industrial transfer and sampling; follow the exact regional SDS.

What should be done after eye contact?
Rinse promptly with gently flowing water, remove contacts when easy, and seek medical advice if irritation persists or exposure was substantial.

What should be done after skin exposure?
Wash the skin with water and mild soap, remove contaminated clothing, and get medical advice for persistent irritation.

What if a worker inhales heated PEG mist?
Move the worker to fresh air and obtain medical evaluation for persistent respiratory symptoms; control future mist generation.

What if PLURIOL E 200 is swallowed?
Rinse the mouth, do not induce vomiting, and obtain poison-center or medical advice where indicated; industrial grade PEG is not an ingestion product.

What is a major spill hazard?
The liquid can leave floors extremely slippery, so containment, absorbent recovery, and thorough final cleaning are important.

Is PLURIOL E 200 classified as hazardous for transport?
No current product-specific transport classification was verified here; confirm UN status, packing group, and mode-specific requirements from the current SDS.

What does a TDS provide?
A technical data sheet describes typical properties, performance positioning, and test conditions; it is not the same as a batch release certificate.

What does an SDS provide?
A safety data sheet describes recognized hazards and controls, first aid, firefighting, storage, accidental release, and transport information for the relevant product and region.

What does a COA provide?
A certificate of analysis records batch-specific results against the parameters and acceptance limits supplied or agreed for that shipment.

Should color be checked?
Yes, when product appearance or final-product clarity matters. The current unsuffixed grade specification must be used rather than borrowing an LS-grade color limit.

Can batch moisture affect performance?
Yes. Water changes the effective formulation balance and can interfere with moisture-sensitive processes; sample handling matters.

Does PLURIOL E 200 always increase viscosity?
No. Viscosity response in a multicomponent formulation is dependent on other ingredients, concentration, temperature, and interactions.

Is PLURIOL E 200 a preservative?
No inherent preservative performance or approved biocidal function was established from the manufacturer product information.

Is PLURIOL E 200 a strong degreasing solvent?
Not universally. The product is hydrophilic, and heavy-oil cleaning normally depends on other suitable surfactants and formulation components.

Can PLURIOL E 200 help disperse pigments?
It can be screened as a polar processing aid in selected systems, but dispersion efficiency and storage stability must be measured rather than presumed.

Why might nonionic character matter?
It avoids adding an intentionally charged surfactant group, potentially simplifying some formulations, while trace ions from manufacturing remain relevant to sensitive applications.

Does PLURIOL E 200 contain ethylene glycol?
PEG 200 is chemically different from ethylene glycol. Any residual low-molecular-weight glycol content is an impurity specification question requiring the correct COA or analytical data.

Does PLURIOL E 200 contain 1,4-dioxane?
No batch-specific residual level was established here; for impurity-sensitive applications request validated test results and limits as required.

What should be confirmed before ordering?
Exact grade and suffix, current TDS/SDS, batch documentation, impurity limits, packaging, application requirements, quantity, and commercial availability.

Can suppliers guarantee the same results in every detergent?
No. Product performance must be demonstrated in the full formulation and validated for its intended storage, use, and substrate conditions.

How can a buyer contact Ataman Kimya?
Contact Ataman Kimya to discuss the intended application, appropriate grade, technical documentation, packaging options, current availability, and a quotation.

TECHNICAL SUMMARY

PLURIOL E 200 is a technical-grade, liquid polyethylene glycol with nominal average molecular mass near 200 g/mol, recognized as a water-soluble, nonionic solubilizing aid, humectant, and processing ingredient. Its linear oxyethylene chains and two hydroxyl end groups explain its hydration, polarity, solvent compatibility, and potential usefulness as a chemical intermediate.

Product-specific manufacturer material identifies a representative kinematic viscosity of approximately 60 mm2/s at 20 °C and a liquid state at ordinary room temperature. Other numerical values often quoted for PEG 200, PEG 200-600, or separately named LS grades must be distinguished from a certified PLURIOL E 200 commercial specification.

The main technical considerations are moisture pickup, grade and chain-length control, relevant impurity limits, and effects on formulation residue or drying behavior. Selection for a regulated market or a sensitive manufacturing process should follow review of current TDS, SDS, COA, and application-specific validation.
