Science

Mechanism of Action

LAURYL METHACRYLATE/GLYCOL DIMETHACRYLATE CROSSPOLYMER operates through several distinct mechanisms. It acts as a film former, providing a subtle layer, and functions as a thickener and emulsion stabilizer to optimize product consistency. Its absorbent properties are key to its mattifying effects, efficiently adsorbing excess skin oils to reduce shine. Furthermore, when engineered as porous microspheres (Microsponge® technology), it facilitates the gradual and sustained release of active ingredients, thereby enhancing efficacy, reducing potential irritation, and improving formula stability over time.
