发明名称 Water resistant personal care polymers
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, based on the weight of said polymer, one or more (meth)acrylate monomer selected from at least 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 hydrophobic monomer, including hydrophobically substituted (meth)acrylate monomers, with alkyl chain length from C8 to C22 and, (iii) optionally crosslinker, and, (b) at least one suncare active. Optionally, the polymer further includes a stage 2 polymer comprising, as polymerized 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 containing acid functional group, and (iii) optionally, a crosslinker.

主权项 1. A personal care composition comprising: (a) a polymer, wherein the polymer comprises, as polymerized units, based on the weight of the polymer: 20 parts by weight butyl acrylate/40 parts by weight ethylhexyl acrylate/38.5 parts by weight methyl methacrylate/1.5 parts by weight methacrylic acid/0.075 parts by weight allyl methacrylate; and (b) at least one suncare active;wherein the polymer is formed in a single stage.
