Polyquaternium-10

Polyquaternium-10 is a cationic cellulose derivative created by reacting hydroxyethylcellulose with a quaternary ammonium compound. It's one of the most widely used conditioning polymers in hair care and personal cleansing products because it deposits on hair and skin surfaces to provide excellent wet and dry combability, reduces static, and enhances foam quality without building up over time. Formulators favor it for its ability to substantively bind to negatively charged hair and skin, providing conditioning benefits even in rinse-off products, while maintaining compatibility with most surfactant systems at typical use levels of 0.1-1.0%.
