Abstract: A water-in-oil emulsified cosmetic preparation that, even without substantially comprising a UV scattering agent, exhibits a high UV protection effect. This water-in-oil emulsified cosmetic preparation includes: 6%-40% by mass of a UV absorber (A); at least 15% by mass of a non-volatile polar oil component (B) containing an ester bond (and not including the UV absorber (A)); and 0.5%-15% by mass of an oil phase thickener (C). It is particularly preferable that the present invention also includes a powder (D) having an average particle diameter of no more than 15 μm.

Abstract: An oil-in-water-type emulsion cosmetic contains an ultraviolet ray scattering agent and which has preparation stability in a system where a water-soluble alkyl-substituted polysaccharide derivative and another emulsifying agent coexist is further improved. The oil-in-water-type emulsion cosmetic containing (A) a water-soluble alkyl-substituted polysaccharide derivative, (B) a nonionic surfactant and (C) an ultraviolet ray scattering agent, wherein the blend ratio [(A)/(B)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the nonionic surfactant (B) is 1.54 or less, and the blend ratio [(A)/(C)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the ultraviolet ray scattering agent (C) is 0.02 or less.

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.
