DISPONIL FES 147

DISPONIL FES 147 is an aqueous anionic surfactant based on sodium C12-C14 fatty alcohol ether sulfate with an average of approximately seven ethylene oxide units, used principally in emulsion polymerization and waterborne polymer formulations. Its combination of a charged sulfate group and an ethoxylated chain makes this alcohol ether sulfate useful for emulsification and colloidal stabilization. By adsorbing at interfaces and polymer-particle surfaces, the emulsifier reduces interfacial tension and helps limit particle aggregation.

WHAT IS DISPONIL FES 147?

DISPONIL FES 147 is a sodium fatty alcohol ether sulfate emulsifier supplied as an aqueous liquid containing approximately 27% active matter for industrial polymer-dispersion applications. The approximately seven-unit ethoxylate segment distinguishes this grade from lower- and higher-ethoxylated members of the same surfactant family.

In emulsion polymerization, the anionic emulsifier helps disperse monomers and stabilize the growing polymer particles. Its performance depends on monomer composition, surfactant loading, feed strategy and the rest of the stabilization package.

For waterborne coatings, adhesives and textile binders, the fatty alcohol ether sulfate is relevant mainly through its role in the manufacture or adjustment of the polymer dispersion. A useful latex emulsifier is not automatically the best pigment dispersant, cleaning agent or low-foam wetting additive for every finished formulation.

The underlying chemistry involves ethoxylation of fatty alcohols followed by sulfation and neutralization to the sodium salt. This describes the chemical family rather than a disclosed manufacturing specification for DISPONIL FES 147. Industrial product consists of a distribution of alkyl-chain lengths and ethoxylate homologues in water.

Commercial evaluation should distinguish active content, average EO degree, inorganic salts, pH and preservation system. Neither a generic sodium laureth sulfate description nor an equivalent active percentage alone proves that another surfactant will reproduce the behavior of this emulsifier.

COMMON PRODUCT & CHEMICAL NAMES OF DISPONIL FES 147:

DISPONIL FES 147
DISPONIL® FES 147
Sodium fatty alcohol ether sulfate, approximately 7 EO
C12-C14 fatty alcohol ether sulfate, sodium salt, approximately 7 EO
Sodium alkyl ether sulfate
Alcohol ether sulfate, AES

The first two entries are the commercial product name with and without the trademark symbol. The approximately 7 EO descriptions characterize its chemistry, while sodium alkyl ether sulfate and AES are broader family terms rather than exact substitutes for the grade name.

Sodium lauryl sulfate is a non-ethoxylated alkyl sulfate and must not be confused with this ether sulfate. Likewise, a fatty alcohol ethoxylate without a sulfate group is generally nonionic and is not chemically identical to DISPONIL FES 147.

A verified CAS/EC mapping for the exact supplied product was not established from the available manufacturer documents. No single molecular formula or fixed molecular weight adequately describes the complete aqueous formulation and its homologue distribution. For the delivered product's component identifiers and REACH supply-chain information, please contact Ataman Kimya.

Variable composition does not itself mean that a substance cannot have a CAS or EC number. Family identifiers must therefore not be assigned to DISPONIL FES 147 without confirming the specific supplier documentation.

CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES OF DISPONIL FES 147

The active surfactant has a hydrophobic fatty alkyl chain, an ethoxylated segment and a negatively charged sulfate ester head group with sodium as counterion. A generalized representation is R-O-(CH2CH2O)n-SO3Na, where R is predominantly C12-C14 alkyl and n averages approximately seven.

This representation is a structural pattern for the active homologues, not a molecular formula for the entire commercial liquid. The EO value is an average distribution and does not mean that every molecule contains exactly seven units.

HOW DOES DISPONIL FES 147 WORK AT THE MOLECULAR LEVEL?

At an oil-water interface, the fatty alkyl segment associates with the organic phase while the sulfate and ethoxylate portions interact with water. Adsorption of the alcohol ether sulfate helps disperse the organic phase and introduces negative charge at particle surfaces.

In emulsion polymerization, micelles can contribute to particle nucleation, while adsorbed surfactant helps stabilize polymer particles as they grow. The initiator starts the radical reaction, whereas DISPONIL FES 147 controls interfacial behavior and is not a polymerization initiator.

Main functions:

Reducing surface and interfacial tension
Supporting monomer emulsification
Contributing to polymer-particle stabilization
Influencing particle size and latex properties

Electrolytes, pH, temperature, monomer feed and co-surfactants affect performance. Compatibility with cationic additives must be tested because charge interactions can destabilize an anionically stabilized system. More emulsifier does not automatically produce a better latex and may increase foam or water sensitivity.

PHYSICAL AND CHEMICAL PROPERTIES OF DISPONIL FES 147

General technical characteristics:

Physical appearance: Colorless to slightly yellow liquid
Ionic character: Anionic
Average ethoxylation: approx. 7 EO
Active matter: typically approx. 27% by weight
pH: typically approx. 7.5 in a 10% aqueous dilution at 20 °C
Density at 23 °C: typically approx. 1.05 g/cm3
Sodium sulfate: typically approx. 0.4% by weight
Pour point: Reported below 10 °C in historical technical information
Static surface tension: typically approx. 42 mN/m at 1% active substance and 25 °C
Critical micelle concentration: approx. 0.3 g/L active substance at 25 °C
Water solubility: Readily soluble in demineralized water

These values characterize the approximately 27% active grade in published manufacturer information. Historical technical data should not be interpreted as a current batch certificate or as a guarantee that all currently offered variants have identical specifications.

For formulation calculations, active matter is more useful than the supplied-liquid percentage alone. An addition of 1.00% DISPONIL FES 147 at 27% active matter introduces approximately 0.27% active surfactant into the complete formulation.

The dilution and temperature must accompany any pH comparison. Sodium sulfate and other electrolytes influence the ionic environment, while density is useful when converting between volume and mass dosing. A precise viscosity value is not assigned here because a reliable grade-specific measurement with stated conditions was not verified.

Surface tension and critical micelle concentration describe different behavior. The former measures an interfacial property at a stated concentration, while the latter indicates micelle formation in a defined medium. Neither figure establishes the optimum emulsifier dosage in a monomer-containing formulation.

Published characteristics are guidance values rather than a contractual specification. For current acceptance limits and impurity requirements, including residual 1,4-dioxane where relevant, please contact Ataman Kimya.

USE OF DISPONIL FES 147 IN EMULSION POLYMERIZATION

For acrylic and styrene-acrylic systems, the emulsifier can form part of the monomer pre-emulsion and the stabilization package. It should be evaluated in the actual resin recipe rather than selected solely from its EO number.

Particle size, coagulum, viscosity, conversion and film properties are linked but distinct results. A dispersion stabilized successfully with DISPONIL FES 147 may still require optimization of shear resistance, electrolyte tolerance or final-film water resistance.

As the polymerization proceeds, the available particle surface changes. Distribution of the anionic emulsifier between the water phase, interfaces and particles must therefore be considered together with the feed strategy. Published laboratory results for one latex cannot be transferred unchanged to another monomer system.

SECTORS AND INDUSTRIAL APPLICATIONS OF DISPONIL FES 147

The principal role of this sodium alcohol ether sulfate is in aqueous polymer systems and the products made from their dispersions.

Main areas of use:

Emulsion-polymerized binders
Architectural and industrial coating binders
Waterborne adhesives
Textile and nonwoven binders
Paper-coating and construction dispersions

DISPONIL FES 147 IN COATING-BINDER PRODUCTION

Purpose: Produce a stable aqueous polymer dispersion.
Function: Emulsify monomers and help stabilize polymer particles.
Performance effect: Influence particle formation and latex handling.
Limitations: The emulsifier alone does not guarantee pigment dispersion, scrub resistance or water resistance of the finished coating.

DISPONIL FES 147 IN WATERBORNE ADHESIVES

Purpose: Manufacture or adjust compatible aqueous adhesive dispersions.
Function: Modify interfacial behavior and contribute to dispersion stability.
Performance effect: Support formulation-specific wetting and application behavior.
Limitations: Adhesion, wet-heat resistance and surfactant migration must be tested in the complete adhesive.

DISPONIL FES 147 IN TEXTILE AND PAPER BINDERS

Purpose: Supply stable polymer dispersions for coating or binding processes.
Function: Participate in the binder's emulsification or stabilization system.
Performance effect: Support reproducible dispersion handling.
Limitations: Foam, substrate wetting and drying behavior remain process-dependent.

WHICH PROBLEMS CAN DISPONIL FES 147 HELP SOLVE?

Poor monomer emulsification
The approximately 7 EO alcohol ether sulfate can assist dispersion of compatible monomers in water, provided concentration and mixing are appropriate.

Particle aggregation during polymerization
Adsorption and electrostatic stabilization can help limit aggregation. Initiator chemistry, contamination and reactor conditions still require control.

Inconsistent surfactant dosing
Using active-matter calculations helps compare DISPONIL FES 147 additions between batches and formulations.

Replacement of an alkylphenol-derived emulsifier
Fatty alcohol ether sulfates offer a different hydrophobe chemistry. Any APEO-free claim requires confirmation for the supplied grade and the full formulation.

THINGS TO CONSIDER WHEN USING DISPONIL FES 147

A common mistake is replacing another emulsifier on equal delivered weight without correcting for active matter and chemistry. Differences in concentration and EO distribution can change the entire stabilization balance.

Calculate the delivered and active dosage separately.
Include the product's carrier water in the water balance.
Use controlled water quality for dilution and laboratory comparisons.
Test compatibility before combining the anionic emulsifier with cationic components.
Monitor foam and coagulum instead of assuming every stability problem needs more surfactant.
Assess the final film as well as the liquid latex.

For handling DISPONIL FES 147, avoid splashes and mist, provide suitable ventilation and use eye protection and appropriate chemical-resistant gloves. Product-specific labeling cannot be inferred from a general surfactant-family description.

INITIAL FORMULATION APPROACHES FOR DISPONIL FES 147

The following compositions illustrate development screens rather than validated commercial formulations. Percentages are by weight of the complete mixture and the emulsifier is counted as supplied at approximately 27% active matter. The examples assess different uses and do not define one universal dosage range.

EXAMPLE 1: DISPONIL FES 147 IN AN ACRYLIC MONOMER PRE-EMULSION

Components:

Demineralized water: 50.00%
Butyl acrylate: 26.00%
Methyl methacrylate: 23.75%
DISPONIL FES 147, as supplied: 0.25%
Total: 100.00%

Calculated active surfactant: approx. 0.0675% of the mixture, or approx. 0.136% on total monomer.

Evaluation criteria:

Ease of emulsification
Droplet-size distribution
Creaming and separation over the intended holding period
Foaming during mixing
Compatibility with the proposed polymerization process

Safety note: This is a pre-emulsion screen, not a complete polymerization recipe. Monomer handling, inhibition, reaction heat removal and initiator selection require a separate professional process design.

EXAMPLE 2: DISPONIL FES 147 IN AN AQUEOUS ADHESIVE-DISPERSION SCREEN

Components:

Compatible anionic or nonionic polyurethane dispersion, nominally 50% solids: 95.00%
DISPONIL FES 147, as supplied: 0.75%
Demineralized water: 4.25%
Total: 100.00%

Calculated active surfactant: approx. 0.2025% of the complete mixture.

Evaluation criteria:

Viscosity and immediate compatibility
Substrate wetting and foam
Dry-film appearance
Bond strength against a surfactant-free control
Wet-heat resistance and storage stability

Safety note: The 0.75% addition is a screening level supported by a specific published adhesive example, not a guaranteed optimum for other dispersions. A compatible preservation strategy must be established separately.

DISPONIL FES 147 SIMILAR PRODUCTS AND ALTERNATIVES

Selection of an alternative should compare hydrophobe, EO degree, ionic character, active content, particle-control behavior and finished-film properties.

DISPONIL FES 147 AND LOWER-ETHOXYLATED ALCOHOL ETHER SULFATES

Products averaging two or four EO units belong to the same broad anionic family but differ in hydrophilic structure. Matching the delivered dosage does not ensure matching latex properties.

DISPONIL FES 147 AND HIGHER-ETHOXYLATED ALCOHOL ETHER SULFATES

Grades averaging twelve EO units or more may shift the stabilization balance. Higher ethoxylation is a formulation variable rather than a universal performance improvement.

DISPONIL FES 147 AND ALKYL SULFATES

Non-ethoxylated alkyl sulfates lack the EO segment. Their interfacial behavior and latex performance should be evaluated independently.

DISPONIL FES 147 AND NONIONIC ALCOHOL ETHOXYLATES

Nonionic co-emulsifiers provide a different stabilization contribution and can complement an anionic system. Their use changes formulation balance and requires testing for foam, film formation and stability.

Laboratory and application trials should confirm every substitution or co-emulsifier adjustment.

QUALITY CONTROL AND PURCHASING CRITERIA FOR DISPONIL FES 147

Define the target dispersion and required application performance before comparing prices for the emulsifier.

Information to clarify and review before purchasing:

Exact product name and supplied variant
Active matter and associated test method
EO degree and chemical description
pH with dilution and temperature
Density, appearance and handling characteristics
Inorganic salts and relevant trace impurities
Preservative identity and application compatibility
Batch COA, technical information and current local SDS
Packaging, quantity and delivery requirements

A COA supplies batch-specific results or conformity, technical information describes product characteristics, and an SDS communicates hazards and handling requirements. None of these replaces performance testing of the intended polymer system.

Price comparisons for DISPONIL FES 147 should account for active content, specification, packaging and delivery terms. For availability, current quotation and the supplied variant's documentation, please contact Ataman Kimya.

STORAGE AND HANDLING OF DISPONIL FES 147

Historical manufacturer guidance for this ether sulfate family recommends storage at approximately 20-40 °C in tightly closed containers. HDPE and suitable stainless steel are listed as storage materials. Confirm the current delivered grade's temperature limits and shelf life with Ataman Kimya.

At low temperature the surfactant liquid may become heterogeneous or gel. Gentle warming and mixing may restore homogeneity where the supplier permits, while excessive heat must be avoided because hydrolysis can affect quality. Do not assume that separation is harmless without inspecting and reassessing the batch.

Preservation is part of the delivered-product specification and may change with the supplied variant. Dilution or addition to a polymer dispersion changes the preservation environment, so the original container's storage life does not establish the shelf life of a finished formulation.

Contain spills, prevent entry to drains and recover the surfactant with suitable absorbent material. For current transport classification and any applicable UN number for DISPONIL FES 147, please contact Ataman Kimya.

SAFETY INFORMATION OF DISPONIL FES 147

The exact supplied formulation and its preservatives determine the applicable hazard classification. A current grade-specific local SDS was not verified, so no H code, signal word or claim of non-hazardous classification is assigned here. Please contact Ataman Kimya for the applicable classification and labeling of DISPONIL FES 147.

Use splash protection, protective gloves and clothing suited to the task, and minimize aerosol generation. Preservative information matters when assessing sensitization and suitability for the intended application.

After eye contact, rinse promptly with plenty of water, remove contact lenses if easy to do and obtain medical attention for persistent irritation or significant exposure. Wash contaminated skin and remove affected clothing. Following inhalation of mist, move to fresh air and seek medical advice if symptoms develop.

Keep DISPONIL FES 147 residues out of waterways and manage waste according to local requirements. Regulatory coverage, environmental claims and REACH information must be established for the delivered grade, rather than inferred from an AES family name.

DISPONIL FES 147 - TECHNICAL SUMMARY

DISPONIL FES 147 is an approximately 27% active aqueous anionic emulsifier based on sodium C12-C14 fatty alcohol ether sulfate with approximately seven EO units. Its commercial formulation includes a distribution of active homologues rather than one pure molecule.

The alcohol ether sulfate adsorbs at interfaces and helps stabilize polymer particles. Emulsifier dosage, monomer composition, water quality and process conditions all affect the resulting dispersion.

Active matter, pH, inorganic salts, density and preservation are important purchasing criteria. Exact component identifiers and regulatory coverage must be confirmed for the supplied variant.

Relevant uses include polymer dispersions for coatings, adhesives, textiles, paper and construction materials. Good emulsification alone does not guarantee final-film water resistance, adhesion or low foam.

Protect the product from contamination and unsuitable temperatures, control splashes and mist, and confirm current safety documentation. Ataman Kimya can clarify the offered grade and supply conditions.
