About Polyquaternium-51

Polyquaternium-51 is a polymerized quaternary ammonium salt.[1] The number 51 after Polyquaternium is only an identification number distinguishing different Polyquaterniums; it does not indicate the content or molecular size. Its positively charged portions are used to reduce static electricity in hair and leave a thin film. In cosmetics, it is used to form a thin film on the surface of skin, hair, and nails after application and to leave the skin surface soft and smooth.[2]
