Methyl Methacrylate/Glycol Dimethacrylate Crosspolymer
What is Methyl Methacrylate/Glycol Dimethacrylate Crosspolymer?
Methyl Methacrylate/Glycol Dimethacrylate Crosspolymer is a synthetic polymer created through the copolymerization of methyl methacrylate and glycol dimethacrylate monomers. This results in a highly cross-linked, porous microsphere structure commonly used in color cosmetics, sunscreens, and hair styling products. In formulations, it functions by depositing a continuous, breathable film on the skin or hair surface. This film enhances product adherence, providing resistance to water, sweat, and rubbing while allowing the underlying skin to breathe. Its porous nature also helps absorb excess sebum, contributing to a matte finish and smoother texture without clogging pores. Derived from petrochemical sources, it is valued for stability across a wide pH range and compatibility with other cosmetic ingredients.
