DESCRIPTION

Disponil FES 27 IS is an alkyl ether sulfate surfactant, and Disponil FES 27 IS belongs to the fatty alcohol ethersulfate group of anionic surfactants.
Disponil FES 27 IS is based on native C12-C14 fatty alcohol hydrophobe with approximately 2 ethylene oxide units and sulfate sodium salt functionality.
Disponil FES 27 IS provides surface tension reduction, monomer emulsification, particle stabilization, and wetting behavior in water-based systems.

Disponil FES 27 IS is commonly used in emulsion polymerization because alkyl ether sulfate surfactants can provide improved latex stabilization compared with simple alkyl sulfates.
Disponil FES 27 IS is especially useful in acrylic and related polymer dispersion systems where effective emulsification and stable particle formation are required.
Disponil FES 27 IS can be used alone or with other anionic and nonionic emulsifiers to adjust particle size, coagulum level, viscosity, foam, and mechanical stability.

Disponil FES 27 IS aqueous solutions should be protected from freezing, excessive heat, evaporation, and contamination because these factors can affect viscosity, active content, and product uniformity.
Disponil FES 27 IS should be mixed gently when possible because anionic ether sulfate surfactants can generate foam during handling and formulation.
Disponil FES 27 IS should be used according to supplier recommendations, emulsion polymerization requirements, detergent regulations, workplace safety standards, and the performance requirements of the final formulation.

FIRST AID

Inhalation:
Move to fresh air if mist, aerosol, or vapors are inhaled.
Seek medical attention if coughing, respiratory irritation, or discomfort persists.
Avoid breathing mist during spraying, charging, or heated processing.

Skin Contact:
Wash skin with soap and water after contact.
Remove contaminated clothing if necessary and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists because anionic surfactants can irritate eyes.

Ingestion:
Rinse mouth with water.
Do not induce vomiting.
Seek medical attention if discomfort, nausea, foaming, or significant ingestion occurs.

Note to Physicians:
Treat symptomatically.
Monitor for irritation of eyes, skin, respiratory tract, mucous membranes, or gastrointestinal tract after significant exposure.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid splashing, mist formation, and prolonged skin or eye contact.
Mix slowly to reduce foam generation during dilution, charging, or surfactant blending.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust ventilation where mist, aerosol, or heated vapors may be generated.
Avoid spraying or atomizing without adequate exposure control.

Storage:
Store in tightly closed containers in a clean, temperature-controlled, well-ventilated area.
Protect from freezing, excessive heat, evaporation, microbial contamination, and direct sunlight.
Keep away from strong oxidizers, strong acids, and incompatible reactive chemicals.

Spill and Leak Procedures:
Contain spill with inert absorbent and prevent entry into drains and waterways.
Collect into suitable containers for reuse or disposal according to local regulations and facility procedures.
Clean residues with water if allowed by facility procedure because surfactant residues can create slippery surfaces.

Handling Precautions:
Optimize dosage because Disponil FES 27 IS affects latex particle size, coagulum formation, wetting, foam, viscosity, and final polymer dispersion stability.
Control storage temperature because fatty alcohol ether sulfate liquids can change viscosity, separate, or lose handling quality if exposed to poor storage conditions.
Rotate stock using FIFO practices to maintain consistent active content, viscosity, odor profile, and formulation performance.
