FunctionConditioning

What it is — Polyquaternium-51 (INCI: Polyquaternium-51) is a conditioning polymer used to improve skin and hair feel.

What it does — It is included to help a formula spread smoothly and to leave a soft, conditioned, comfortable surface feel.

Typical use — It appears in moisturisers, serums, conditioners and hydrating formulas, usually as a supporting conditioning agent.

Who it suits / good to know — Broadly suitable across skin and hair types, including sensitive-leaning skin. It shapes texture and feel rather than acting as a headline active.

Safety — DHALIORA grades it low risk: a conditioning polymer that is well tolerated. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk - cationic conditioning polymer, well tolerated.
