About
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.
Function
Skin benefits
- Forms flexible long-wear film
- Adds water resistance to formulations
