Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-2,4,6-Tris(1-Phenylethyl)Phenyl-.Omega.-Hydroxy-, Phosphate, Potassium Salt is a specialized non-ionic surfactant and emulsifier with a unique sterically hindered aromatic head group. This molecular structure provides exceptional stability and performance in demanding formulations, particularly where resistance to electrolytes, pH extremes, and high temperatures is required. It is a critical additive for industries seeking to enhance the stability, clarity, and processing characteristics of complex chemical systems.

Application

• Polymerization Emulsifier: Acts as a highly effective steric stabilizer in emulsion and suspension polymerization processes for styrenics, acrylics, and vinyl acetate.
• Advanced Coating Formulations: Used as a dispersant and wetting agent in high-performance paints, inks, and industrial coatings to improve pigment dispersion and film properties.
• Agrochemical Adjuvants: Enhances the spreading, adhesion, and rainfastness of pesticide and herbicide formulations.
• Personal Care & Cosmetics: Serves as a mild emulsifier and stabilizer in creams, lotions, and hair care products, offering compatibility with sensitive skin formulations.
• Oilfield Chemicals: Employed as a demulsifier component and surfactant in drilling muds and enhanced oil recovery processes.
• Textile & Leather Processing: Functions as a leveling agent, softener, and dyeing assistant in textile and leather treatment baths.
