Polyquaternium-7
Polyquaternium-7 is a synthetic conditioning polymer commonly used in UK shampoos, conditioners, hair masks and body washes. It helps detangle hair, reduce static and leave it feeling silky smooth without weighing it down. You’ll often find it in “anti-frizz” or “moisturising” haircare ranges.
How it works in skincare
In cosmetics and skincare, Polyquaternium-7 is a cationic conditioning agent that binds to the negatively charged surface of hair fibres and skin. It forms a light, flexible film that improves wet combability, reduces friction and helps lock in moisture. In leave-in hair products and body washes it delivers a smooth after-feel and enhances the performance of other conditioning ingredients.
