WebPMMA, also known as poly (methyl methacrylate), is a type of engineering plastic. It is a synthetic, linear polymer of methyl methacrylate. Its spherical-shaped particles scatter light to provide a blurring effect to products. It is a homopolymer that functions as a film-forming agent in cosmetics and personal care products. WebPMMA is a versatile material and has been used in a wide range of fields and applications. The German chemist Fittig and Paul discovered in 1877 the polymeri …
