Hydroxypropyltrimonium Hyaluronate is a cationic derivative of hyaluronic acid, formed by reacting hyaluronic acid with 2-hydroxy-3-(n,n,n-trimethylammonio)propyl chloride. The quaternary ammonium modification gives the molecule a positive charge, which may improve its substantivity to skin and hair surfaces compared to standard hyaluronic acid. According to CosIng, its official recognized function is film forming.
