DISPONIL FES 27 IS

Disponil FES 27 IS is an aqueous anionic surfactant based on sodium fatty alcohol ether sulfate with approximately two ethylene oxide units, used for emulsification, wetting and industrial formulation. Its approximately 27% active concentration offers a liquid form for incorporating ether sulfate chemistry into water-based systems. The amphiphilic surfactant adsorbs at interfaces, with its alkyl region associating with organic material and its negatively charged sulfate head interacting with the aqueous phase.

WHAT IS DISPONIL FES 27 IS?

Disponil FES 27 IS is a commercial aqueous fatty alcohol ether sulfate surfactant, commonly associated with sodium lauryl ether sulfate chemistry, used as an emulsifier and wetting or cleaning ingredient. Its technical identity combines the anionic sulfate group, an ethoxylated fatty alcohol structure and a supplied active concentration of approximately 27%.

For formulation purposes, this is a surfactant concentrate rather than a pure solid compound. The C12-C14 substance identity represents a distribution of fatty alkyl chains and ethoxylation homologues. A nominal two-EO description is an average, not a claim that every molecule has exactly two oxyethylene groups.

The ether sulfate can be evaluated in polymer dispersions and in water-based industrial formulations where wetting, emulsification or foaming is useful. Selection must account for the process rather than relying on the product name alone. An emulsifier that performs well during mixing may still need adjustment for storage stability or the properties of the final film.

At the chemistry-family level, production involves ethoxylation of fatty alcohols, sulfation of the resulting alcohol ethoxylates and neutralization to the sodium salt. Water and residual process components form part of the commercial concentrate. These general steps do not specify a manufacturing recipe or the detailed impurity profile of an individual batch.

Commercial grades can differ in alkyl distribution, ethoxylation, active matter, electrolyte content and other composition details. The full IS designation should therefore remain in purchase inquiries. Similar names or matching nominal concentration do not demonstrate identical supplied composition.

COMMON PRODUCT & CHEMICAL NAMES OF DISPONIL FES 27 IS

Disponil FES 27 IS
Disponil FES 27IS
FES 27 IS
Sodium laureth sulfate
Sodium lauryl ether sulfate
SLES
Sodium fatty alcohol ether sulfate
Alcohols, C12-14, ethoxylated, sulfates, sodium salts

The first names are trade or grade designations, whereas the remaining names describe the surfactant chemistry. Sodium laureth sulfate is the familiar ingredient name, and SLES is its common abbreviation. The C12-C14 designation is more specific about the alkyl-chain range than a broad family name.

Historical product literature also associates this grade with the earlier designation Texapon NSO IS. That historical name is not a guarantee that any material sold under a similar name is interchangeable with the present offer.

Sodium lauryl sulfate, abbreviated SLS, is a different surfactant without the ethoxylated spacer. Sodium alkyl sulfonates are also different, since a sulfonate and a sulfate ester do not have the same bonding arrangement. These names should not be substituted for SLES in a specification.

CAS, EC AND CHEMICAL IDENTIFICATION OF DISPONIL FES 27 IS

Product name: Disponil FES 27 IS
Common chemical abbreviation: SLES
Chemical identity: alcohols, C12-14, ethoxylated, sulfates, sodium salts
CAS No: 68891-38-3
EC No: 500-234-8

The identifiers above describe the C12-C14 ether sulfate substance identity. They should not be interpreted as an assay or as a complete list of components in the aqueous commercial product. The exact offered material must be matched to its composition documentation.

Broader sodium laureth sulfate references also use the number 9004-82-4. It should not automatically replace the more specific C12-C14 identity used here. No single molecular formula or fixed molecular weight is assigned to this distribution-based concentrate.

MOLECULAR STRUCTURE OF DISPONIL FES 27 IS

A useful general representation for the surfactant anion and sodium counterion is R-O-(CH2CH2O)n-SO3Na. Here R denotes a fatty alkyl group and n represents a distribution with an average around two for the nominal grade description. This notation expresses a structural family rather than a unique molecule.

The alkyl segment supplies affinity for oils, monomers and other organic phases. Ether oxygens contribute a hydrated spacer between that segment and the terminal sulfate region. The sulfate head is anionic, while the sodium ion balances its charge in the supplied salt.

The presence of an EO segment does not make the whole molecule nonionic. Its charged sulfate head determines its anionic surfactant character. Likewise, the sulfate ester structure means that describing this chemistry as sulfate-free would be incorrect.

HOW DOES DISPONIL FES 27 IS WORK?

Adsorption at an oil-water or monomer-water interface helps reduce interfacial tension and supports droplet formation during mixing. At solid-water interfaces, improved wetting can help water contact substrates or particulate material. At air-water interfaces, the same surfactant activity contributes to foam formation.

In a latex, adsorption of anionic emulsifier can help maintain separation between dispersed particles through electrostatic repulsion and a hydrated interfacial region. This does not make stability independent of the surrounding water. Dissolved salts, multivalent ions and other charged ingredients can change interactions between particles.

Concentration, mixing history, temperature and the co-surfactant package influence the result. Cationic ingredients deserve particular compatibility testing because they may associate with anionic surfactants. A system that looks homogeneous immediately after mixing can still separate or develop deposits later.

PHYSICAL AND CHEMICAL PROFILE OF DISPONIL FES 27 IS

The substantiated basic profile is a liquid sodium fatty alcohol ether sulfate with approximately 27% active matter and approximately two EO units. These are typical descriptors, not a complete release specification. The balance of the supplied product includes water and may include other process-derived or added components.

Active matter must be distinguished from total dry residue. Residual inorganic salts or other nonvolatile components can contribute to dry residue without representing the same quantity of anionic surfactant. Compare analytical results only when the method and reporting basis are clear.

For pH, a number without sample concentration and test conditions can be misleading. Viscosity likewise depends on temperature, concentration and electrolyte content. Numerical pH, density, viscosity and salt limits specific to the offered IS grade should be obtained from Ataman Kimya, rather than borrowed from another ether sulfate product.

Aqueous dilution is a practical advantage, but concentration changes can alter rheology and foaming. Additions should be controlled to avoid excessive air entrainment. Appearance and flow should be assessed after allowing entrained air to dissipate.

DISPONIL FES 27 IS IN LATEX DEVELOPMENT

Ether sulfate emulsifiers are established ingredients in emulsion polymerization. For a trial using the IS grade, assess its role in the pre-emulsion, reactor charge and subsequent particle stabilization according to the selected process. The surfactant supports interfaces, it does not replace the initiator or determine the polymer's chemical identity.

Useful development measurements include pre-emulsion separation, particle-size distribution, filter residue, coagulum and latex viscosity. Follow these with mechanical stability and storage observations. Where the dispersion becomes a coating or adhesive, assess the actual dried film or bond as well.

Emulsifier concentration should be reported on a defined basis, such as active surfactant per total formulation or per monomer mass. Those percentages are not interchangeable. A dose taken from another grade or expressed on an unclear basis should not be transferred directly to a reactor.

SECTORS AND APPLICATIONS OF DISPONIL FES 27 IS

Polymer dispersions and waterborne binders
The main formulation question is whether the emulsifier package provides suitable particle formation and process stability. Coatings and adhesives add further requirements such as film integrity, adhesion and moisture response. Strong foaming or good initial emulsification alone cannot answer those questions.

Industrial washing formulations
Anionic detergency and wetting make SLES chemistry relevant to aqueous washing systems, especially where foam is acceptable or useful. Removal of the actual soil, rinse behavior, substrate compatibility and water quality should be evaluated together. High foam is a limitation in equipment designed for low-foam operation.

Textile wetting and washing trials
The ether sulfate can be assessed as a wetting or washing component in a compatible bath. Fabric wetting, foam under circulation, rinsing and interaction with the bath's other chemicals matter more than a generic claim of suitability for every textile process.

Other aqueous industrial blends
Dispersion or emulsification trials may include this anionic surfactant where the chemistry is appropriate. Such evaluation does not establish compatibility with every pigment, resin, electrolyte or organic solvent. The intended formulation remains the basis for selection.

COSMETIC CONTEXT OF DISPONIL FES 27 IS

Sodium Laureth Sulfate is a recognized cosmetic ingredient name used for cleansing and emulsifying functions. That chemistry-level recognition does not qualify an industrial grade for personal care. For such an inquiry, contact Ataman Kimya to confirm the offered grade's intended use, composition and required documentation.

WHICH PROBLEMS CAN DISPONIL FES 27 IS HELP ADDRESS?

Poor wetting of an appropriate substrate can be investigated by measuring contact or wetting behavior with the surfactant present. This avoids choosing a dose solely from how much foam appears.

Difficulty preparing a monomer or oil pre-emulsion can be approached through interfacial testing and emulsifier-package optimization. Mixing energy and phase addition order still need control.

Uncontrolled particle aggregation may require adjustment of the surfactant package and the water's ionic environment. Simply increasing ether sulfate cannot correct every cause of coagulation.

Unclear raw-material comparisons can be resolved by converting concentrate additions to active matter. A 27% solution and a high-active paste are not equivalent on an equal-weight basis.

USE CONSIDERATIONS FOR DISPONIL FES 27 IS

Establish whether foam is useful, acceptable or detrimental in the process.
Specify the complete grade designation and actual active value.
Keep the percentage basis visible in calculations and batch sheets.
Include water and electrolytes introduced with the concentrate.
Screen cationic additives and multivalent-ion exposure separately.
Control agitation to distinguish stable dispersion from entrained air.
Validate performance after storage and under the intended use conditions.

The handling assessment must cover concentrated surfactant exposure, splashes and aerosols. Neither a near-neutral pH nor suitability of SLES chemistry in some consumer formulations makes a supplied concentrate harmless.

INITIAL FORMULATION APPROACHES FOR DISPONIL FES 27 IS

The following proposed blends are laboratory starting points, not commercially validated products or producer-recommended dosages. Every percentage is by weight of the complete blend and raw materials are counted as supplied. The nominal active calculations assume a 27% ether sulfate concentrate and a 100% active nonionic co-surfactant.

EXAMPLE 1: DISPONIL FES 27 IS IN A FOAMING WASHING TRIAL

Components:

Ether sulfate concentrate, nominal 27% active: 10.00%
Compatible alcohol ethoxylate, nominal 100% active: 2.00%
Trisodium citrate, anhydrous: 0.50%
Demineralized water: 87.50%
Total: 100.00%

This exploratory blend contains 2.70% nominal anionic active matter and 4.70% total nominal surfactant active matter. It is intended for foaming washing evaluation, not an automatic dishwasher or another low-foam machine. The chosen nonionic must be identified and checked for aqueous compatibility.

Evaluation criteria:

Removal of a defined soil from representative test panels
Foam generation, persistence and rinsing
Appearance, pH and viscosity over the trial period
Sensitivity to intended use dilution and water hardness
Compatibility with the tested substrate

No commercial shelf life is assigned. Assess preservation and safe handling before any storage or broader use.

EXAMPLE 2: DISPONIL FES 27 IS IN A TEXTILE WETTING BATH

Components:

Ether sulfate concentrate, nominal 27% active: 1.00%
Compatible alcohol ethoxylate, nominal 100% active: 0.30%
Demineralized water: 98.70%
Total: 100.00%

The bath contains 0.27% nominal anionic active matter and 0.57% total nominal surfactant active matter. These levels are selected for screening and do not establish an optimum textile-process dose. No oxidant, dye or cationic finishing agent is included in this initial compatibility blend.

Evaluation criteria:

Wetting time on the actual fabric
Foam during representative agitation or circulation
Uniformity of wetting and rinse behavior
Response to temperature and intended bath chemistry
Fabric appearance after the selected treatment

Introduce further bath chemicals only in a separately assessed trial. Any additions require a new mass balance and compatibility review.

DISPONIL FES 27 IS AND ALTERNATIVE SURFACTANTS

A higher-active SLES concentrate may reduce the amount of water transported, but handling and dose calculation change. For 1 kg of nominal anionic active matter, a 27% concentrate requires approximately 3.704 kg of raw material, compared with approximately 1.429 kg for a nominal 70% product. This is an active-mass comparison, not proof of grade equivalence.

Higher-EO ether sulfates change the hydrated spacer and may alter formulation behavior. Sodium alkyl sulfates remove that EO spacer entirely. Both options require testing rather than substitution based only on the common sulfate function.

Nonionic alcohol ethoxylates or alkyl polyglucosides offer different ionic and compatibility profiles. They can be evaluated as alternatives or co-surfactants, but cannot be assumed to preserve an anionic latex's stabilization mechanism. Select the package against the full performance requirement.

QUALITY CONTROL AND PURCHASING CRITERIA FOR DISPONIL FES 27 IS

An inquiry should identify the IS grade, intended application and required quantity before comparing price. Request anionic active matter and its method, appearance criteria, water or solids information, pH preparation, viscosity conditions and relevant electrolyte limits. Where the end use calls for impurity or preservation information, define the required evidence explicitly.

The COA reports batch results against the agreed specification. A TDS describes typical product properties, while an SDS covers hazard communication and handling information. These documents serve different purposes and should describe the same offered material.

Calculate cost per unit of usable active matter and include freight, packaging and handling. A lower kilogram price can be offset by additional water, process changes or poor performance. Contact Ataman Kimya for missing grade-specific values and current supply details.

STORAGE AND HANDLING OF DISPONIL FES 27 IS

Keep the concentrate in clean, closed, compatible containers and prevent contamination or evaporation. Avoid excessive heat and uncontrolled cold exposure. Maintain clean pumps and transfer lines and avoid high-speed mixing that unnecessarily entrains air.

Temperature changes can affect the appearance and flow of concentrated surfactants. If a container shows separation, deposits or unusual viscosity, obtain product-specific guidance before heating or returning it to use. For confirmed temperature limits, reconditioning instructions and shelf life of the offered IS grade, contact Ataman Kimya.

Contain spills promptly because surfactant solutions create slippery surfaces. Use suitable absorbent and collect contaminated material for appropriate disposal. Prevent concentrated product and washings from entering drains or surface waters.

SAFETY INFORMATION OF DISPONIL FES 27 IS

SLES chemistry can cause eye and skin irritation, and concentrate exposure must be controlled. Use splash goggles, suitable chemical-resistant gloves and protective clothing for transfer or mixing. Avoid generating mist and provide ventilation appropriate to the task.

After eye exposure, rinse immediately and continuously with clean water, remove contact lenses if readily possible and seek urgent medical advice. Wash contaminated skin and remove soiled clothing. If mist exposure causes persistent symptoms, move to fresh air and obtain medical help.

An ingredient-family assessment does not establish the final classification of the exact commercial concentrate. No unverified H statement, UN number or transport exemption is assigned here. Obtain current classification, environmental requirements and shipment information for the offered material from Ataman Kimya.

DISPONIL FES 27 IS - TECHNICAL SUMMARY

Disponil FES 27 IS is a liquid aqueous anionic surfactant based on sodium fatty alcohol ether sulfate. Its typical description includes approximately 27% active matter and an average of approximately two EO units.

The C12-C14 substance identity is associated with CAS 68891-38-3 and EC 500-234-8. This distributed chemistry does not justify assigning one fixed molecular formula or molar mass to the commercial concentrate.

Interfacial adsorption supports emulsification, wetting, detergency and foam. In polymer-dispersion development, particle stability and the properties of the final application must be evaluated separately.

Active-matter basis, water balance, electrolyte exposure and co-surfactant compatibility are central to selection. Proposed washing and wetting blends are laboratory screens, not validated commercial recipes or universal dosing instructions.

The full IS designation and current offered composition should guide quality, storage, safety and transport decisions. Grade-specific information and supply conditions should be confirmed with Ataman Kimya.
