About
A synthetic acrylamide-based polymer (PolyAMPS) used as a film former and stabiliser in skincare and hair products. The polymer itself is inert; residual monomer is the only relevant concern, well controlled at cosmetic grade.
Function
Skin benefits
- Forms even, flexible films on skin
- Helps keep emulsions stable
- Improves wear of leave-on products
Known concerns
- Trace residual acrylamide monomer (cosmetic grade keeps this very low)
- Synthetic polymer with limited biodegradability
