Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Mono(C16-18-Unsatd. Alkyl) Ethers, Phosphates is a specialized nonionic surfactant phosphate ester, derived from ethoxylated unsaturated C16-18 fatty alcohols. This compound is valued for its excellent emulsifying, wetting, and antistatic properties, particularly in formulations requiring compatibility with electrolytes and stability across a wide pH range. It is a critical ingredient for industrial formulators in sectors such as agrochemicals, textiles, and metalworking fluids, where performance under demanding conditions is essential.

Application

• Agrochemical Emulsifiers & Adjuvants: Primary emulsifier for pesticide concentrates (EC, EW) and a key component in tank-mix adjuvants to enhance spray droplet retention and penetration.
• Textile Processing: Used as a lubricant, antistatic agent, and emulsifier in fiber spin finishes and fabric softener formulations.
• Metalworking Fluids: Acts as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic metalworking fluids.
• Industrial & Institutional Cleaners: Provides detergency and emulsification in heavy-duty alkaline and acid cleaner formulations.
• Personal Care (Rinse-off products): Functions as a mild surfactant and emulsifier in shampoos, body washes, and other rinse-off applications.
• Paint & Coating Additives: Utilized as a pigment dispersant and grinding aid to improve color development and stability.
• Leather Processing: Employed as a fatliquoring agent and emulsifier in leather tanning and finishing.
• Paper & Pulp Industry: Serves as a debonding agent and dispersant in paper coating and recycling processes.
