Overview
Methyl methacrylate crosspolymer (CAS 25777-71-3 ) is a crosslinked acrylic polymer supplied as a fine powder for use in personal care and industrial formulations.
It functions primarily as a rheology modifier and surface-feel enhancer, controlling texture and flow without altering the active chemistry of a formulation.
In cosmetics and skincare, it is incorporated into foundations, primers, and sunscreens to deliver a soft-focus, silky skin feel while improving spreadability and reducing tackiness.
Coating formulators use it as a matting agent and texture additive in architectural and industrial coatings, where it modifies surface slip and gloss without requiring solvent-based additives.
In adhesives and sealants, the crosslinked particle structure contributes to rheological stability, preventing sagging in vertical-application products.
Plastics compounders incorporate it as a processing aid or surface modifier to improve the tactile and optical properties of finished polymer articles.
Methyl methacrylate crosspolymer is commercially available as a free-flowing white powder, typically in micronized particle grades suited to cosmetic and coating applications.
Cosmetic-grade material is the most common specification, with particle size distribution being the key parameter. Bulk and smaller packaged quantities are standard across the supply chain.
