Hydrophobic powder that has the noticeable effects of low oil absorption and a low apparent specific volume is stably blended into a sunscreen cosmetic as a UV radiation dispersing agent to produce a sunscreen cosmetic that has remarkably improved ease of washability after use.

Abstract: The present invention provides an oil-in-water external skin preparation that has an excellent stability, excellent rough-surface correction effect, and excellent texture. The oil-in-water external skin preparation of the present invention is characterized by comprising (a) an aqueous phase containing resin particles obtained from 100 parts by weight of a vinyl-type monomer and 0.1 to 20 parts by weight of a monomer represented by the below general formula (I), (b) an oil phase, and (c) a surfactant comprising one or more selected from polyoxyethylene hydrogenated castor oil, silicone-type surfactants, and sulfonic acid-type surfactants, in the amount of 0.01 to 5% by mass of the total amount of the external skin preparation and 30% by mass or more of the total amount of surfactants. (In the above formula, R represents a hydrogen atom or a methyl group, 1 represents 1 to 50, and m represents 1 to 50.

Abstract: The present invention provides a modified powder that is obtainable by coating the surface of a base powder with a hydrophobizing agent and a cationic surfactant. In the modified powder described above, it is preferable that the amount of coated hydrophobizing agent and the amount of coated cationic surfactant are 3 to 90% by mass and 0.5 to 10% by mass, respectively, relative to the self weight of the base powder. In the modified powder described above, it is preferable that the mass ratio of the coated hydrophobizing agent and the coated cationic surfactant is from 1:1 to 9:1. In addition, the present invention provides a cosmetic composition comprising the above modified powder wherein the modified powder and the base powder have an ultraviolet scattering effect. In the cosmetic composition described above, it is preferable that the blended amount of the modified powder is from 0.5 to 100% by mass.

Abstract: The present invention provides a self tanning cosmetic containing 0.2-20.0 mass % of dihydroxyacetone and 0.1-10.0 mass % of an inorganic pigment powder whose surface is treated with silica coating followed by a hydrophobing treatment. The present invention provides a cosmetic that has superior storage stability, is free of discoloration and odor generation, and achieves both the decorative effect of the pigment immediately following application and the long term dyeing effect of dihydroxyacetone.

Abstract: An object of the present invention is to provide a composite powder, cosmetics containing the same, and the production method of the same. When blended into cosmetics, the above-described composite powder corrects skin surface unevenness and imperfections in skin color, renders a natural finish, and have durability in finished makeup. In order to achieve the above-mentioned object, the composite powder of the present invention comprises flaky substrate powder and barium sulfate particles or zinc oxide particles that adhere to the surface, in protrusions, of the substrate powder.
