Polyquaternium-22
Other names: acrylic acid-diallyldimethylammonium chloride polymer
Harm score: 3 (Harmless chemicals)
Polyquaternium-22 is a special type of polymer used in the cosmetics industry and the production of hygiene and cleaning products. Its other name is acrylic acid-diallyldimethylammonium chloride polymer. As the name suggests, it is derived from acrylic acid and diallyldimethylammonium chloride. This substance belongs to a broader group of polyquaterniums - polymers that contain quaternary ammonium groups. These groups provide the polymer with certain positive charges that attract to negatively charged surfaces such as human skin and hair.
Polyquaternium-22 is most commonly used in cosmetics as a conditioning and antistatic agent. Its most typical use is in shampoos and hair conditioners, as it can reduce static electricity, provide shape to the hairstyle, and keep hair moisturized. However, because of its moisturizing properties, it is also used in other cosmetic products such as various body lotions and creams. Due to its anti-static properties, it can also be used in products that are designed to keep hair smooth, such as styling gels or hair sprays.
