BUTYL ACRYLATE/ISOPROPYLACRYLAMIDE/PEG-18 DIMETHACRYLATE CROSSPOLYMER.

Valuable CAS - / EMULSION STABILISING, FILM FORMING, SKIN CONDITIONING

An intelligent thermo-responsive polymer that undergoes a fascinating phase transition from liquid to gel at body temperature (~32°C), creating an optimal delivery system for active ingredients. This smart material forms a breathable film reservoir on skin that enhances ingredient penetration while providing sustained hydration and demonstrated skin brightening effects.
