Polyquaternium-7 is a water-soluble cationic polymer widely used in hair and skin care products for its conditioning, film-forming, and anti-static properties. It is part of the polyquaternium family, known for improving hair manageability, softness, and shine.
Because it carries a positive charge, Polyquaternium-7 binds to the negatively charged hair and skin surfaces, reducing static electricity, frizz, and flyaways. It is compatible with most anionic and nonionic surfactants, making it suitable for shampoos, conditioners, and styling products. It also adds viscosity and texture to formulations.
