Polyquaternium-7 is a water-soluble, cationic conditioning polymer that enhances the texture, softness, and manageability of hair and skin. Known for its antistatic and film-forming properties, it is a staple ingredient in shampoos, conditioners, body washes, and styling products.
It works by forming a thin protective film on the surface of hair and skin, locking in moisture while smoothing frizz and tangles. Unlike heavy silicones, Polyquaternium-7 delivers a lightweight conditioning effect that rinses easily without residue.
