About
A nail and skin coating film former built from butyl acrylate (flexibility) and isobornyl methacrylate (hardness). The polymer is well tolerated; sensitization risk lives in trace unreacted monomers, not the film itself.
Function
Skin benefits
- Hard yet flexible films for nail and skin coatings
- Strong gloss and chip resistance
- Stable, durable long-wear performance
- Polymer form limits skin penetration
Known concerns
- Residual butyl acrylate is a known skin sensitizer
- Isobornyl methacrylate residuals can also sensitize
- Microplastic environmental persistence
- Higher concern in nail-product overspray scenarios
