Description

Siloxanes And Silicones, Di-Me, 3-Hydroxypropyl Me, (3-Hydroxypropyl)Dimethylsilyloxy-Terminated, Ethers With Polyethylene-Polypropylene Glycol Mono-Me Ether is a specialized organomodified silicone surfactant, engineered by combining a polydimethylsiloxane backbone with hydrophilic polyether and hydroxypropyl groups. This unique hybrid structure provides exceptional surface activity, compatibility with both aqueous and organic systems, and stable foam control. It is a critical performance additive for formulators in the personal care, coatings, and polyurethane foam industries seeking to enhance wetting, emulsification, and process stability.

Application

• Polyurethane Foam Stabilizer: Acts as a key surfactant in flexible and rigid PU foam production, controlling cell structure and ensuring uniform foam rise.
• Personal Care & Cosmetics: Used in hair conditioners, skin creams, and antiperspirants as an emollient, conditioning agent, and to improve spreadability and silky feel.
• Coatings & Inks Additive: Enhances substrate wetting, leveling, and slip in water-based and solvent-based formulations, reducing surface defects.
• Industrial Surfactant: Serves as an emulsifier and compatibilizer in agrochemicals, textile auxiliaries, and metalworking fluids.
• Release Agent Component: Incorporated into mold release formulations for plastics, rubber, and composite materials.
• Antifoaming Agent: Effective in controlling foam in various chemical processing and industrial cleaning applications.
