Description

Polyquaternium-33 is a high-performance cationic polymer belonging to the polyquaternium family of conditioning agents. This compound is valued for its exceptional substantivity to hair and skin, providing superior detangling, softness, and antistatic properties in personal care formulations. It is a critical ingredient for manufacturers in the cosmetics and toiletries industry seeking to enhance the sensory profile and performance of rinse-off and leave-on products. The product is supplied under the identifier CAS No. 69418-26-4.

Application

• Hair Care Products: A primary conditioning agent in shampoos, conditioners, hair masks, and styling products for detangling, smoothness, and manageability.
• Skin Care & Cleansers: Used in body washes, facial cleansers, and liquid soaps to improve skin feel, provide a silky afterfeel, and reduce irritation.
• Color Cosmetics: Functions as a conditioning and film-forming agent in mascaras, eyeliners, and foundations to enhance application and wear.
• Shaving Preparations: Incorporated into shaving gels and foams to provide lubricity and a protective, soothing effect on the skin.
• Industrial & Institutional (I&I) Care: Employed in commercial fabric softeners and industrial surfactants for its cationic charge and softening capabilities.
