Description

Siloxanes And Silicones, Polyoxyalkylene- CAS NO 87244-72-2 is a specialized organomodified silicone surfactant, engineered by incorporating polyoxyalkylene (typically polyoxyethylene or polyoxypropylene) groups into a siloxane backbone. This unique molecular architecture provides exceptional surface activity, foam control, and compatibility with both aqueous and organic systems. It is a critical performance additive for formulators in the personal care, coatings, polyurethane foam, and textile industries seeking to enhance wetting, leveling, and emulsification properties.

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 shampoos, conditioners, and creams as an emulsifier, hair conditioning agent, and to provide a smooth, silky feel.
• Coatings & Inks: Functions as a flow and leveling agent, wetting agent, and defoamer in water-based and solvent-based formulations.
• Textile & Fiber Processing: Employed as a softener, lubricant, and anti-static agent to improve fabric hand feel and processing performance.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
• Industrial Cleaning: Serves as a surfactant and defoamer in industrial and institutional cleaning products.
