Polyquaternium-67

Polyquaternium-67 is a quaternized cellulose derivative, specifically a 2-hydroxyethyl cellulose ether reacted with n,n,n-trimethyl-n-oxiranylmethylammonium chloride and n-dodecyl-n,n-dimethyl-n-oxiranylmethylammonium chloride. It is a cationic polymer used primarily in hair and skin care formulations. Its quaternary ammonium groups impart antistatic and conditioning properties, while its film-forming ability helps coat and smooth hair and skin surfaces.
