About QUATERNIUM-79 HYDROLYZED KERATIN
A cationic keratin protein — clings to hair and skin to repair damage, add strength, and lock in moisture. Popular in hair repair products.
Detailed Analysis
Quaternium-79 Hydrolyzed Keratin is a quaternized derivative of hydrolyzed keratin protein, where keratin hydrolyzates are modified with dimethylammonio hydroxypropyl groups and long-chain alkyl (C16-C18) substituents. The quaternary ammonium modification gives it a positive charge, allowing it to bind strongly to negatively charged hair and skin surfaces. This results in excellent conditioning, film-forming, and antistatic properties. CIR has reviewed hydrolyzed keratins and quaternium compounds and found them safe as used.
