Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer
What is Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer?
Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer is a synthetic polymer formed by combining acrylonitrile, methacrylonitrile, and methyl methacrylate monomers through polymerization. It appears as fine, porous particles commonly incorporated into pressed powders, loose powders, and oil-absorbing cosmetic formulations. In products, it functions by trapping excess sebum and moisture due to its highly absorbent structure, which helps maintain a lightweight texture and prevents clumping. This ingredient contributes to the dry-touch sensation in mattifying makeup, enhancing wear time on oily areas without altering color or coverage. Primarily used in facial cosmetics, it supports formulations aiming for shine control and improved blendability, distinguishing it from traditional absorbents like talc by its tailored porosity and compatibility with other powders.
