About
A large urethane-acrylate copolymer used for structure and wear, not for treating skin.
This copolymer functions mainly as a binder or film former. The finished polymer itself should have low skin penetration, but the chemistry behind it raises the usual residual-monomer question seen with acrylate and urethane systems. It is acceptable as a formulation aid, though not a particularly elegant skin ingredient.
