EasySperse polymers are effective dispersants of hydrophobic actives.
EasySperse polymer is based on a copolymer of the monobutyl/ethyl ester of poly (methyl vinyl ether/maleic acid) partially neutralized with sodium hydroxide. The material is supplied as a 25 percent aqueous solution and is an excellent film-former.
EasySperse P-20 polymer is a spray-dried, optimized composite polyvinyl pyrrolidone (PVP) and methyl vinyl ether/maleic acid half ester. It offers superior stability of hydrophobic actives and excellent compatibility with formulation ingredients.
