Abstract: The present invention provides stable, quick drying aqueous compositions useful in making traffic markings having excellent low temperature flexibility which comprise (i) one or more vinyl or acrylic emulsion polymers chosen from single stage and multi-stage emulsion polymers, the polymer or at least one stage thereof having both a calculated glass transition temperature (calculated Tg) of from −25 to 0° C., and a calculated Hansch parameter of 1.4 to 2.25, and (iii) one or more fillers, extenders and/or pigments, wherein the composition has a percent pigment volume concentration (% PVC) of from 50 to 80% and, preferably, a volume solids of from 50 to 75%. The compositions may comprise one or more silanes, and one or more polyamines and a volatile base, such as ammonia.

Abstract: Provided are personal care compositions comprising a polyacrylate oil gel composition comprising (a) hydrophobic oil ester, and (b) polymer beads comprising (i) 65 to 90 weight % of a soft phase comprising polymerized units derived from first monoethylenically unsaturated monomers having a Tg of less than 25° C. after polymer formation, and (ii) 10 to 35 weight % of a hard phase comprising polymerized units derived from second monoethylenically unsaturated monomers having a Tg of more than 40° C. after polymer formation, wherein the polymer beads have an average particle size of from 2 to 30 μm.
