Polyquaternium 10

Polyquaternium-7 is a synthetic polymer, specifically a cationic copolymer of acrylamide and diallyldimethylammonium chloride, widely used in skincare and haircare products as a conditioning and hydrating agent. It's known for its ability to smooth frizz, add lubricity, provide hold, and protect hair from damage. It also helps to hydrate and nourish skin, and can even thicken serums. It's typically sold as an aqueous solution, and is readily soluble in water.
