About
A reactive vinyl acid used to make acrylate polymers in nail and film-forming products. Free monomer is corrosive and a known sensitizer — only acceptable as polymer with negligible residual monomer.
Function
Skin benefits
- Monomer for film-forming acrylate polymers (used as polymer, not as residual monomer)
- Necessary intermediate in nail polymer chemistry
Known concerns
- Free monomer is corrosive and a skin/respiratory sensitizer
- Documented occupational dermatitis in nail-product workers
- Should never appear at appreciable free-monomer levels in finished products
