About

A complex methacrylate-thiol crosslinker used in UV-cured nail and lash systems. Safe only fully polymerised, since residual monomers are well known skin sensitisers.

Skin benefits

  • Multifunctional methacrylate/thiol crosslinker for UV-cured nail and lash products
  • Forms durable polymer networks via thiol-ene chemistry

Known concerns

  • Unreacted methacrylate monomers are strong skin sensitisers
  • Thiol groups have noticeable odour and can be irritating
  • Suitable only for cured (polymerised) systems, not leave-on skincare
  • Limited individual safety data outside cured polymer matrix
