About this ingredient

Methyl Methacrylate Crosspolymer is a synthetic polymer formed by cross-linking methyl methacrylate monomers, creating a three-dimensional network structure. In cosmetic formulations, it functions as a film-forming agent that creates a smooth, adherent coating on the skin or hair surface, providing long-wear properties and enhanced texture. It is commonly used in long-lasting makeup, nail products, and skincare formulations to improve product durability and aesthetic finish.
