Description

Polyquaternium-39 is a high-performance, synthetic cationic copolymer widely recognized for its exceptional conditioning and film-forming properties. This versatile polymer is crucial for formulators seeking to enhance product performance through superior substantivity, manageability, and long-lasting effects. It is an essential ingredient for manufacturers in the personal care, home care, and industrial sectors requiring reliable multifunctional additives.

Application

• Hair Care Formulations: A primary conditioning agent in shampoos, conditioners, and hair masks, providing excellent detangling, softness, and shine without buildup.
• Skin Care & Cosmetics: Used in creams, lotions, and makeup to improve skin feel, provide moisturization, and enhance the stability and texture of emulsions.
• Color Cosmetics: Acts as a film-former and binder in mascaras, eyeliners, and foundations, improving wear resistance and water repellency.
• Household & Industrial Cleaners: Functions as an antistatic agent and deposition aid in fabric softeners, hard surface cleaners, and car care products.
• Pharmaceutical Topicals: Employed as a viscosity modifier and stabilizer in gels, creams, and ointments for controlled release and enhanced application properties.
