Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hexadecyl-.Omega.-Hydroxy-, Phosphate, Sodium Salt is a nonionic surfactant phosphate ester, specifically the sodium salt of a hexadecyl alcohol ethoxylate phosphate. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, particularly in challenging formulations. It is a critical ingredient for manufacturers requiring stable, high-performance surfactant systems. Key industries that rely on this specialty chemical include agrochemicals, textiles, industrial cleaning, and personal care.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide concentrates (EC, SC) and foliar sprays to enhance coverage and efficacy.
• Textile Processing: Used as a scouring, leveling, and dyeing assistant to improve fiber wetting and dye penetration.
• Industrial & Institutional (I&I) Cleaning: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and alkaline cleaning formulations.
• Personal Care & Cosmetics: Functions as a mild emulsifier and solubilizer in creams, lotions, and hair care products.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants.
• Paint & Coatings: Used as a pigment dispersant and grinding aid to improve color development and stability.
• Leather Processing: Applied in fatliquoring and dyeing processes to ensure even distribution of oils and dyes.
