About
A synthetic polymer used to form a film or improve texture, generally low in direct toxicity but not especially skin-beneficial on its own.
C4-18 Alkyl Methacrylate/Methacryloyloxyethyl Phosphorylcholine Copolymer is a copolymer of Methacryloyloxyethyl Phosphorylcholine and C4-18 alkyl methacrylate. High molecular weight polymers like this are mainly used to adjust texture, wear, film formation, or hydration feel and usually have low dermal absorption. The main caveats are occasional irritation from residual monomers or impurities and, for some polymers, persistence in the environment.
