Hydroxypropyltrimonium Lemon Protein

Hydroxypropyltrimonium Lemon Protein is a quaternized protein derived from lemons. The protein is hydrolyzed into smaller, more manageable fragments, and then modified to carry a positive charge. This allows it to effectively bind to hair and skin, providing conditioning, moisturizing, and protective benefits.
