About
A PEG-4 dimethacrylate-crosslinked acrylates polymer used to build clear, flexible films. Cured polymer is too large to penetrate skin; like all (meth)acrylate systems, low residual monomer is the safety lever.
Function

- Forms clear flexible films
- Stabilises long-wear emulsions
- Improves rub-off resistance
Known concerns
- Residual methacrylate monomer must be controlled
- Can sensitise nail technicians at uncured state
- No leave-on use on broken skin
