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: An oil-in-water emulsified sunblock cosmetic has excellent feeling when used and maintains a high ultraviolet-ray protective effect even upon contact with water or sweat. The oil-in-water emulsified sunblock cosmetic contains an (A) ultraviolet-ray protective agent and a (B) fatty acid forming a solid at room temperature, the cosmetic is characterized in that 51% or less of the fatty acid is neutralized, and the formulation ratio ((A)/(B) of the (A) ultraviolet-ray protective agent to the (B) fatty acid is in the range of at least 0.1 and less than 10.0. The cosmetic exhibits the unprecedented and surprising property of contact with water causing an improvement to the ultraviolet-ray protective ability. It is preferable for the cosmetic to contain an (C) oily component having IOB of 0.5 or higher.

Abstract: The object is providing a water-in-oil emulsion sunscreen cosmetic having a property not present in the prior art, in which UV protection ability improve upon contact with water, sweat and the like in comparison with that directly after application, and also having pleasant texture and easy to wash off. The present invention provides a water-in-oil emulsion sunscreen cosmetic comprising (A) 6 to 40 mass % of a UV protective agent; (B) an organic-modified clay mineral; (C) an oil-phase-thickening agent, other than (B) and (D) a silicone-based surfactant having an HLB of less than 8, wherein the ratio, [total quantity of component (B) and component (C)]/[total quantity of (E) non-volatile liquid oils except silicone oils], is 0.04 or more and less than 0.68.

Abstract: A sunscreen cosmetic achieves high ultraviolet ray protection effect even when restricting a blended amount of the liquid ultraviolet ray absorbing agents ethylhexyl methoxycinnamate and octocrylene, that is stable and has excellent texture, and does not resulting in an unnatural whiteness on application. A sunscreen cosmetic comprises: (A) 0.5 to 10.0 mass % of t-butyl methoxydibenzoylmethane and/or diethylamino hydroxybenzoyl hexyl benzoate; (B) 0.5 to 5.0 mass % of bis-ethylhexyloxyphenol methoxyphenyl triazine; (C) 0.5 to 5.0 mass % of ethylhexyl triazone; (D) 5 to 50 mass % of an ester oil to which the ingredients (A), (B) and (C) have a solubility, at 25° C., of 10% or more; and (E) 1.5 to 12 mass % of an ultraviolet ray scattering agent; wherein the total blended amount of the ingredients (A), (B) and (C) is 1.5 to 15 mass % and the total blended amount of ethylhexyl methoxycinnamate and octocrylene is 3 mass % or less.
