"Isopropyl ester of PVM/MA copolymer" is a copolymer of (poly)methyl vinyl ether (PVM) and maleic anhydride (MA) the anhydride of maleic acid (= unsaturated dicarboxylic acid ; see below poly(methyl vinyl ether-alt-maleic anhydride).

The substance is used in cosmetic formulations. The copolymer acts as an antistatic agent (reduces static charges by neutralizing the electrical charge on the surface of e.g. hair), binder (binds cosmetic preparations containing powder) and emulsion stabilizer (supports the formation of emulsions and improves the resistance and durability of emulsions).
