Hydroxypropyltrimonium Hydrolyzed Wheat Protein

Hydroxypropyltrimonium Hydrolyzed Wheat Protein is a quaternized protein derived from wheat. The hydrolysis process breaks down wheat protein into smaller fragments, making it easier for them to penetrate and adhere to hair and skin. The quaternization adds a positive charge, enhancing its conditioning and film-forming properties.
