Abstract: The invention provides a cosmetic having strong resistance to contact with water, clothing, fingers, and abrasion with little decline (post-contact) in the cosmetic effects such as UV blocking protection as well as excellent feel on use. The cosmetic contains: (A) plate-shaped powder, (B) 6-40% by mass UV absorber, and (C) cationic surfactant.

Abstract: A purpose of the present invention is to provide an oil-in-water emulsion cosmetic having a fresh feeling in use like that of a skin-care cosmetic such as a milky lotion, while also allowing titanium oxide or zinc oxide, which are ultraviolet scattering agents, to be stably blended into the oil phase, and also providing excellent sunscreen effects. The present invention relates to an oil-in-water emulsion cosmetic characterized by comprising (A) an ultraviolet scattering agent having a hydrophobic surface; (B) a water-soluble alkyl-substituted polysaccharide derivative; (C) a higher alcohol; and (D) a non-ionic surfactant. The emulsion cosmetic of the present invention preferably has a viscosity, measured by a B-type viscometer at 30° C., of 12,000 mPa·s or lower.

Abstract: A water-in-oil emulsified cosmetic preparation that, even without substantially comprising a UV scattering agent: exhibits a higher UV protection effect than immediately after application, as a result of coming in contact with moisture, has excellent appearance, usability, and washability. The water-in-oil emulsified cosmetic preparation includes 6%-40% by mass of a UV absorber (A), an oil phase thickener (B), and at least one hydrophobic powder (C) selected from (i)-(iii), namely (i) hydrophobized talc, (ii) silicone powder having an average particle diameter of at least 30 μm, and (iii) crosslinked polymethyl methacrylate powder having a crosslinking density of at least 40%; and not including a UV scattering agent or containing no more than 6% by mass of same.

Abstract: An oil-in-water type emulsion cosmetic exhibits a high-level sunscreen effect and has a low viscosity and a high stability and is easy to use. The oil-in-water type emulsion cosmetic includes (A) an agar microgel, (B) one or more kinds of powders selected from (b1) a clay mineral powder and (b2) a highly oil-absorbing spherical powder, (C) a polyoxyethylene-hardened castor oil having an HLB value of 10-17; (D) an oil-soluble UV absorber, (E) 0.01-0.13 mass % of an (acrylate/alkyl acrylate (C10-30)) cross polymer, and (F) 0-0.5 mass % of a UV scattering agent, and is characterized in that the viscosity at 25° C. is not higher than 10,000 mPa·s.
