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

Known concerns

  • Residual butyl acrylate is a known skin sensitizer
