摘要:Described are personal care compositions comprising a polymer comprising: (a)one or more polymer comprising, as polymerized units, (i) 75% to 35% by weight, basedon the weight of said polymer, one or more (meth)acrylate monomer selected from atleast one of C1-C4 (meth) acrylate, (meth)acrylic acid, styrene, or substituted styrene, and(ii) 25% to 65% by weight, based on the weight of said polymer, one or more hydrophobicmonomer, including hydrophobically substituted (meth)acrylate monomers, with alkylchain length from C8 to C22 and, (iii) optionally crosslinker, and, (b) at least one suncareactive. Optionally, the polymer further includes a stage 2 polymer comprising, aspolymerized units, (i) 10-99% of one or more monomer which has a Tg of more than 80°C. after polymer formation, (ii) 1-10% of one or more (meth)acrylate monomer containingacid functional group, and (iii) optionally, a crosslinker.
