Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mono-C11-15-sec-Alkyl Ethers, Phosphates, Sodium Salts is a specialized anionic surfactant belonging to the phosphate ester class, valued for its excellent emulsifying, wetting, and dispersing properties. Its unique structure, featuring a C11-15 secondary alkyl chain and ethoxylated phosphate groups neutralized to sodium salts, provides a balance of oil solubility and water compatibility, making it a versatile performance additive. This chemical is essential for formulators in industries such as agrochemicals, metalworking, and industrial cleaning, where stable emulsions and effective surface activity are critical for product performance.

Application

• Agrochemical Emulsifiers & Adjuvants: A key component in pesticide and herbicide formulations, enhancing the emulsification of active ingredients and improving spray droplet retention and coverage on plant surfaces.
• Metalworking Fluids: Acts as an effective emulsifier and lubricity agent in soluble oils and semi-synthetic metalworking fluids, providing stability and corrosion protection.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, alkaline cleaners, and floor care products for its superior wetting and soil emulsification capabilities.
• Textile Processing: Functions as a lubricant, antistatic agent, and emulsifier in fiber spinning, weaving, and finishing operations.
• Paint & Coating Additives: Serves as a pigment dispersant and grinding aid in water-based coatings, improving color development and system stability.
• Personal Care (Rinse-off products): Employed as a mild surfactant and foam booster in specialized industrial skin cleansers and rinse-off formulations.
