Abstract: Provided are skin care compositions that are useful as SPF and UV absorption boosters in formulations containing inorganic metal oxides. The compositions comprise (a) 0.1 to 20 weight % inorganic metal oxide particles, based on the weight of the composition, (b) 0.1 to 15 weight % copolymer particles dispersed in an aqueous medium, wherein the copolymer particles comprise polymerized units derived from (i) 0.1 to 20 weight % of phosphorus acid monomers, and (ii) 80 to 99.9 weight % of comonomers, (c) 0.1 to 35 weight % silicone fluid, based on the total weight of the composition, and (d) a dermatologically acceptable carrier. Also provided are methods of protecting skin from UVA and UVB damage comprising topically administering such compositions to the skin, and methods of boosting the SPF or UV absorption of a sunscreen composition containing inorganic metal oxide particles comprising including such copolymer particles in the composition.

Abstract: A multistage colored polymer particle is provided, having a core comprising polymerized units of a monoethylenically unsaturated carboxylic acid core monomer and a non-ionic ethylenically unsaturated core monomer; an inner shell comprising polymerized units of a non-ionic ethylenically unsaturated inner shell monomer; a monoethylenically unsaturated carboxylic acid inner shell monomer; optionally, an aliphatic inner shell monomer; and, optionally, a first polymerizable dye monomer; an outer shell comprising polymerized units of a non-ionic ethylenically unsaturated outer shell monomer; a monoethylenically unsaturated non-carboxylic acid outer shell monomer; optionally, a second polymerizable dye monomer; and, optionally, an aliphatic outer shell monomer; wherein the core, when dry, contains at least one void; and wherein the multistage colored polymer particle comprises polymerized units of polymerizable dye monomer. Skin care formulations comprising multistage colored polymer particles and methods of using same are also provided.
