About
A styrene/acrylates/acrylonitrile copolymer used as a film former and opacifier. Polymer form is essentially inert, but residual acrylonitrile (a possible carcinogen) and styrene push this into use-with-awareness territory.
Function
Skin benefits
- Forms durable opacifying films
- Provides product structure and visual interest
- Improves long-wear performance
- High molecular weight limits direct skin penetration
Known concerns
- Acrylonitrile monomer is an IARC Group 2B possible carcinogen
- Styrene residuals (IARC 2B)
- EU residual-monomer scrutiny
- Microplastic environmental concerns
- More sensitization potential than non-acrylonitrile copolymers
