Used primarily as a silicone-based surfactant in personal care formulations, this copolymer provides excellent surface activity and foam stabilization. It is commonly found in shampoos, conditioners, and skin care products where it enhances spreadability, imparts a silky feel, and improves conditioning performance. Its unique structure allows for effective water repellency while maintaining breathability, making it suitable for use in hair styling products and protective skin coatings. Additionally, it helps reduce tackiness in silicone elastomer blends, improving the texture and sensory attributes of final products. Due to its low surface tension, it is also utilized in coatings and polishes to promote leveling and reduce surface defects.
