Good

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A high-molecular-weight nylon-style polymer used to form a flexible, water-resistant film on skin or hair. Inert at the cosmetic interface; the main caveat is environmental persistence rather than skin safety.
