Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(9-Octadecenyloxy)-, Ammonium Salt is a high-purity, nonionic-ionic hybrid surfactant derived from oleyl alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile functional additive. It is primarily used by formulators in the personal care, agrochemical, and industrial cleaning sectors who require stable, mild, and effective surface-active agents.

Application

• Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and hair conditioners, offering mildness and skin compatibility.
• Agrochemical Adjuvants: Enhances the spreading, penetration, and efficacy of pesticides and herbicides on plant surfaces.
• Industrial & Institutional (I&I) Cleaners: Provides superior wetting and soil suspension in hard surface cleaners and degreasers.
• Textile Processing: Used as a leveling agent, lubricant, and emulsifier in fiber processing and dye baths.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to improve color development and stability.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants.
