Description

Hydroxypropyltrimonium Hydrolyzed Soy Protein is a cationic protein derivative derived from natural soy, engineered to provide superior conditioning and substantivity. This specialty ingredient is valued for its ability to impart exceptional softness, manageability, and film-forming properties to hair and skin. It is a critical raw material for formulators in the personal care, cosmetic, and hair care industries seeking natural-derived, high-performance conditioning agents.

Application

• Hair Conditioners & Treatments: Primary conditioning agent in rinse-off and leave-in formulations to improve combability, reduce static, and enhance shine.
• Shampoos & Cleansers: Added to surfactant systems to provide conditioning benefits and mitigate protein loss during washing.
• Skin Care Products: Used in creams, lotions, and serums as a moisturizing and film-forming agent to improve skin feel and barrier function.
• Color Care & Repair Products: Helps protect chemically treated hair, improving tensile strength and reducing porosity.
• Styling Products: Imparts hold and flexibility in mousses, gels, and sprays while improving manageability.
• Men's Grooming Products: Key ingredient in beard oils, balms, and shampoos for softening and conditioning coarse hair.
