    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 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.

    Abstract: A lip cosmetic has a high transparency without giving unnatural whiteness and exerts a remarkable effect of ultraviolet ray protection over a broad wavelength range including the UVA and UVB regions. The lip cosmetic includes (A) at least 5% by mass of UV absorbers; wherein said (A) UV absorbers comprises (A1) at least one UV absorber selected from a group consisting of octocrylene, dimethicodiethylbenzalmalonate and diethylamino hydroxybenzoyl hexyl benzoate, and (A2) ethylhexyl methoxycinnamate; (B) a high-viscosity oil component in a range of 30% by mass to 70% by mass thereof; (C) a low-viscosity oil component in a range of 20% by mass to 40% by mass thereof, and (D) titanium dioxide and zinc oxide of which a total content is at most 0.5% by mass thereof; and wherein a sun-protection-factor (SPF) of the lip cosmetic is at least 20, and a critical wavelength thereof is at a shortest 370 nm.
