Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Octadecyl-.Omega.-Hydroxy-, Phosphate is a high-purity, nonionic surfactant and emulsifier derived from stearyl alcohol and ethylene oxide, subsequently phosphorylated. This specialized chemical is valued for its excellent emulsifying, dispersing, and antistatic properties in complex formulations. It is a critical performance additive for manufacturers in the personal care, industrial lubricants, textile processing, and agrochemical sectors seeking stable, high-performance emulsions and surface-active solutions.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and hair conditioners, providing a smooth texture and enhancing product stability.
• Industrial Lubricants & Metalworking Fluids: Functions as an emulsifier and anti-wear additive, improving the lubricity and stability of oil-in-water emulsions.
• Textile Processing: Used as a softening agent, lubricant, and antistatic agent in fiber spin finishes and fabric softeners.
• Agrochemical Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates, aiding in the formation of stable emulsions upon dilution.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Paper & Pulp Industry: Utilized as a defoamer component and processing aid to enhance sheet formation and drainage.
