Product Brief of Emulsifier S-185
Emulsifier S-185 is a non-ionic surfactant (note: there is a possible typo "non-ionic" written as "anionic" in one document), synthesized by condensing fatty alcohol with ethylene oxide (also named fatty alcohol polyoxyethylene ether). It appears as an off-white paste to solid.
Key technical indicators include a pH of 5.0-7.0 (1% aqueous solution), hydroxyl value of 110-120mgKOH/g, and moisture content ≤1.0%. With a theoretical HLB value of 8.5-9.5, it disperses in water and acts as an oil-loving emulsifier for w/o emulsions. It also works as a softener for chemical fibers, silk, and cigarette filter materials. Packaged in 200kg iron drums or 50kg plastic drums, it has a 2-year shelf life when stored in dry, ventilated areas and transported as a general chemical.
Excellent Emulsifying Performance with Targeted Type
As an oil-loving (lipophilic) non-ionic surfactant, Emulsifier S-185 excels at forming stable water-in-oil (w/o) emulsions. Its ability to disperse evenly in water ensures consistent emulsion quality, a key advantage for industries requiring reliable phase mixing—no phase separation even in long-term storage, reducing product waste.
Stable Technical Indicators for Consistent Quality
It boasts strict and stable technical parameters: pH 5.0~7.0 (1% aqueous solution) matches most industrial systems, avoiding pH-induced product degradation; hydroxyl value 110~120mgKOH/g guarantees uniform reactivity; moisture content ≤1.0% (wt%) prevents water-related defects, ensuring batch-to-batch consistency.
Versatile Compatibility & Wide Adaptability
Being a non-ionic surfactant, it has strong compatibility with anionic, cationic, and other non-ionic additives. This eliminates compatibility issues in multi-component formulations, making it suitable for diverse industrial processes—from textile finishing to chemical fiber softening—without adjusting existing formulas.
Convenient Packaging & Long Shelf Life
Supplied in 200Kg iron drums (for large-scale production) and 50Kg plastic drums (for small-batch use), it meets different production needs. Stored in dry, ventilated areas (per general chemical standards), it has a 2-year shelf life, reducing inventory turnover pressure and ensuring long-term usability.
Eco-Friendly & Safe Handling
As a non-ionic surfactant derived from fatty alcohol and ethylene oxide, it has low environmental impact compared to harsh surfactants. It requires only general chemical storage and transportation, no special hazardous material protocols—lowering handling costs and simplifying compliance for manufacturers.

Product Uses
W/O Emulsion Preparation
It serves as a core lipophilic emulsifier for w/o emulsion production. Whether in industrial coatings, lubricants, or cosmetic creams, it stabilizes the water phase dispersed in oil, preventing emulsion breakdown—critical for products needing long-term stability, like industrial rust-preventive emulsions.
Chemical Fiber Softener
Added to chemical fiber post-processing, it forms a smooth film on fiber surfaces. This reduces friction between fibers, improving fabric softness and hand feel. It works for polyester, nylon, and other synthetic fibers, enhancing product comfort without affecting fiber strength.
Silk Post-treatment Agent
In silk processing, it enhances silk's natural luster and softness. It penetrates silk fibers to reduce brittleness from washing/processing, maintaining silk's elasticity and drapability—ideal for high-end silk garments and home textiles requiring premium texture.
Cigarette Filter Material Softener
Applied to cigarette filter materials (e.g., acetate fiber), it softens the filter's surface. This improves the tactile experience when holding cigarettes and reduces irritation to the lips/mouth, while not affecting the filter's filtration performance for tar and harmful substances.
