| 摘要 |
A film-forming cosmetic composition that provides superior feel, look, and wear characteristics while also delivering UV protection to the skin. The cosmetic composition may be in the form of a water-in-oil emulsion that includes a water compatible film-forming polymer, a sunscreen active, and one or more particles. The foundation provides suitable feel and appearance during application, UV protection, and excellent wear and appearance after application, yet provides flexible, light feel. |

1. A skin cosmetic in the form of a foundation composition, comprising:
an aqueous phase that includes from 0.5% to 10% by weight based on the weight of the composition of film-forming polyvinylpyrrolidone polymer that adheres to skin when the composition is applied to the skin; 0.1%-16% by weight based on the weight of the composition of a sunscreen active selected from the group consisting of titanium dioxide, zinc oxide, 2-ethylhexyl-p-methoxycinnamate, 4-isopropyldibenzoylmethane, 4-(1,1-dimethylethyl)-4′-methoxydibenzoylmethane, 2-ethylhexyl-2-cyano-3,3-diphenylacrylate, 2-phenylbenzimidaole-5-sulfonic acid; 0.01%-40% by weight based on the weight of the composition of a multitude of particles comprising a mixture of Surface Topography Modifier particles, Locking Oil Absorber particles, and Releasing Oil Absorber particles wherein the multitude of particles are present at a ratio of Surface Topography Modifier:Locking Oil Asorber:Releasing Oil Absorber of from 25:25:1 to 15:5:1; wherein aluminum starch octenylsuccinate having a size in the range of 10 to 75 microns is the Surface Topography Modifier particle, mixture of talc and isopropyl titanium triisostearate and ethylene/methacrylate copolymer microspheres having a particle size of 15-50 microns are the Locking Oil Absorber particles and silica having a particle size of 1-20 microns is the Releasing Oil Absorber particle and said foundation composition optionally further comprising particles selected from the group consisting of hydrated silica, silicone treated silica beads, mica, talc, nylon 12, nylon 6, polyethylene, methyl silsesquioxane resin, polymethylmethacrylate, crosslinked polydimethylsiloxanes, polyamide, polystyrene, polyethylene, Styrene/DVB copolymers, and mixtures thereof from 0.5% to 30% of propylene glycol as the plasticizing solvent, wherein the ratio of propylene glycol to film-forming polyvinyl pyrrolidone is between 10:1 to 1:1 and the foundation composition comprising at least one of an emulsifier, an elastomer, a metal oxide, and a fragrance wherein the metal oxide is included in an amount of from 0.05% to 15% by weight based on the weight of the foundation composition, and the metal oxide is selected from the group consisting of pigmentary grade iron oxide particles, pigmentary grade titanium dioxide particles, and combinations thereof and the elastomer is included in the foundation composition in an amount of from 0.01% to 15% by weight based on the weight of the foundation composition, and the elastomer is a cross-linked organo polysiloxane elastomer; and an oil phase that includes from 1% to 80% by weight based on the weight of the composition of an oil. |
