Hair Conditioning Ingredients

Hair conditioning ingredients improve hair manageability, reduce static, and repair surface damage. The class includes cationic quaternary ammonium compounds (behentrimonium chloride, cetrimonium chloride), cationic polymers (polyquaterniums), silicones (dimethicone, amodimethicone), hydrolysed proteins, and panthenol. Regulatory scrutiny focuses on quaternary ammonium compound skin irritation thresholds under SCCS review and the environmental fate of silicones (D4, D5, D6 cyclic siloxanes) under REACH. This hub lists hair conditioning ingredients with their safety ratings, SCCS opinions, and regulatory references.
