About
A film-forming polymer used in nail and coating products. The polymer itself is inert, but any leftover phthalate monomer would be a concern — several phthalates are CMR-banned in EU cosmetics. Use-with-awareness ingredient.
Function
Skin benefits
- Durable, glossy nail film
- Excellent thermal and chemical stability
- Lower tack than acrylate films
Known concerns
- Phthalate class includes EU-banned CMR phthalates — residual monomer is the concern
- Allyl-functional monomer residue can sensitise
- Limited cosmetic-specific clinical data for the polymer
- Better suited to nail than skin contact
