STEARYLVINYL ETHER/MA COPOLYMER.

Valuable CAS 28214-64-4 / ANTISTATIC, EMULSION STABILISING, FILM FORMING, VISCOSITY CONTROLLING

STEARYLVINYL ETHER/MA COPOLYMER is a synthetic polymer that forms a lightweight, protective film on the skin's surface. This action helps to reduce trans-epidermal water loss, contributing to improved skin hydration and texture. Beyond its film-forming capabilities, it serves multiple roles in cosmetic formulations, including stabilizing emulsions and controlling viscosity.

Science

Mechanism of Action

This copolymer operates primarily as a film-forming agent. Upon application, it creates an imperceptible barrier on the skin, which physically impedes moisture evaporation. This protective layer not only contributes to prolonged hydration but also refines the skin's tactile feel and overall appearance.
