Description

Siloxanes and Silicones, di-Me, 3-hydroxypropyl Me, ethers with polyethylene glycol monoacetate, polyethylene-polypropylene glycol and polyethylene-polypropylene glycol monoacetate is a specialized, multi-functional silicone polyether copolymer designed to impart unique surface-active properties. This compound matters for formulators seeking to enhance wetting, spreading, and compatibility in complex aqueous and non-aqueous systems. Key industries that need this advanced additive include personal care, coatings, agrochemicals, and polyurethane foam manufacturing, where it acts as a powerful surfactant, emulsifier, and foam control agent.

Application

• Personal Care & Cosmetics: Acts as a high-performance emulsifier and stabilizer in creams, lotions, and sunscreens, improving texture and skin feel.
• Coatings & Inks: Serves as a flow and leveling agent, reducing surface tension to enhance substrate wetting and film formation.
• Agrochemical Formulations: Used as a superior adjuvant and spray additive to improve the adhesion and spreading of pesticides and herbicides on plant surfaces.
• Polyurethane Foams: Functions as a cell opener and foam stabilizer in flexible slabstock and molded foam production.
• Industrial Cleaners: Enhances the detergency and rinsability of hard surface cleaners and degreasers.
• Textile & Leather Processing: Employed as a softener, lubricant, and anti-foam agent in various finishing baths.
