Young Chemist Polyquaternium-7 (PQ-7) is a cosmetic chemical widely used in personal care products due to its beneficial properties. It is a cationic polymer that provides multiple benefits for the hair and skin. Here is a description, the benefits, instructions for use, and cautions associated with PQ-7:
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.
In skincare products, PQ-7 enhances slip, provides a silky texture, and leaves the skin feeling conditioned and comfortable after cleansing. Its excellent water solubility and compatibility with a wide range of ingredients make it a favorite among formulators seeking enhanced performance and stability.
