A protein-based conditioning ingredient combining hydrolyzed wheat protein with quaternary ammonium functionality for enhanced hair and skin deposition.

This ingredient is a hybrid conditioning system: hydrolyzed wheat protein (from gluten) that has been reacted with quaternary ammonium compounds (3-chloro-2-hydroxypropyltrimethylammonium chloride and soya-alkyldimethyl ammonium chloride) to improve substantivity to skin and hair. It functions as a conditioning and antistatic agent and is listed in CosIng. The ingredient contains hydrolyzed gluten proteins, requiring allergen labeling in the EU under Regulation 1169/2011. Otherwise, it has a favorable safety profile at cosmetic concentrations.
