About
Silica particles surface-functionalized with methacryloyloxypropyl groups, used in nail and dental gel formulations to build a hard photocured film. Uncured methacrylate residue can sensitize skin.
Function
Skin benefits
- Viscosity control and structure in nail/dental polish
- Photopolymerizable into a hard durable film
- Inert silica backbone
Known concerns
- Methacryloyl group is a known sensitizer in the unreacted state
- Used predominantly in nail products — skin contact should be minimized
- Fully cured polymer is far less reactive than monomer residue
