Abstract:
Described are personal care compositions comprising a polyacrylate oil gel, comprising: (a) at least one cosmetically acceptable hydrophobic ester oil, and (b) one or more polymers comprising: (i) a first polymerized unit, comprising: (1) 75% to 35% by weight, based on the weight of said polymerized unit, one or more (meth)acrylate monomers selected from at least one of C1-C4 (meth)acrylate, (meth)acrylic acid, styrene, or substituted styrene, and (2) 25% to 65% by weight, based on the weight of said polymerized unit, one or more hydrophobic monomers, including hydrophobically substituted (meth)acrylate monomers, with alkyl chain length from C6 to C22 and, (ii) a second polymerized unit, comprising: (1) 10-99% by weight, based on the weight of said polymerized unit, one or more monomers which has a Tg of more than 80° C. after polymer formation, (2) 1-10% of one or more (meth)acrylate monomers containing acid functional group, and (iii) optionally, a crosslinker.
