Description

Poly(Dimethylsiloxane), Ethoxylated, Hydroxypropoxylate End-Capped is a specialized silicone polyether copolymer, also known as a dimethicone copolyol. This compound is engineered to combine the hydrophobic, film-forming, and antifoaming properties of polydimethylsiloxane with the hydrophilic, surfactant, and emulsifying characteristics of polyoxyethylene and polyoxypropylene chains. Its unique structure makes it an indispensable performance additive for creating stable, high-quality formulations. Key industries that rely on this material include personal care, coatings, textiles, and agrochemicals, where it functions as a versatile surfactant, emulsifier, and foam control agent.

Application

• Personal Care & Cosmetics: Acts as a key surfactant and emulsifier in shampoos, conditioners, skin creams, and sunscreens, providing enhanced spreadability, softness, and moisture retention.
• Coatings & Inks: Used as a flow and leveling agent, wetting agent, and defoamer in water-based and solvent-based coating systems to improve surface finish and eliminate defects.
• Textile Processing: Serves as a softener, lubricant, and anti-foaming agent in fiber production and fabric finishing baths.
• Agrochemical Formulations: Functions as a superior surfactant and spreader in pesticides and herbicides, enhancing droplet retention and coverage on plant surfaces.
• Polyurethane Foam Production: Employed as a cell stabilizer and surfactant to control cell structure and uniformity in flexible and rigid foam manufacturing.
• Industrial Cleaning: Utilized in industrial and institutional cleaning products as a surfactant and defoamer for hard surface cleaners and rinse aids.
