Polyquaternium7

Polyquaternium-7 (PQ-7) is a water-soluble polymer that is commonly used as a conditioning agent and film-forming agent in cosmetic formulations. It is derived from the polymerization of diallyldimethylammonium chloride, resulting in a positively charged molecule.

Polyquaternium-7 (PQ-7) is a highly effective conditioning and film-forming polymer widely used in modern haircare and personal care formulations for its exceptional ability to enhance softness, smoothness, and moisture retention. Known for its gentle, lightweight conditioning effect, PQ-7 helps improve product feel and performance without weighing down the hair or leaving residue. It is a key ingredient in shampoos, conditioners, hair masks, body washes, face cleansers, shaving products, leave-in treatments, and styling formulas, delivering instant smoothness and hydration.

In haircare, Polyquaternium-7 helps reduce frizz, tangles, and breakage, enhancing both wet and dry combability. It improves shine, strengthens the hair shaft, and forms a protective barrier that prevents moisture loss and environmental damage. Its anti-static properties make it ideal for curly, dry, chemically treated, or heat-styled hair. PQ-7 also boosts the performance of surfactant-based systems, increasing foam quality and making them feel gentler on skin and hair.
