Polyquaternium-7 ( PQ-7 ) CAS 108464-53-5

Polyquaternium-7 is a cationic copolymer and a mild surfactant widely used in personal care formulations. As a high-performance conditioning agent, Polyquaternium-7 provides excellent antistatic properties, reduces frizz, and significantly improves wet and dry combability. This unique surfactant does not cause buildup, unlike many traditional polymers. Another key feature of Polyquaternium-7 is its compatibility with anionic, nonionic, and amphoteric surfactant systems.
Applications of Polyquaternium-7 include shampoos, conditioners, body washes, facial cleansers, and styling products, where this surfactant enhances foam creaminess and leaves hair or skin smooth and manageable.
