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 sprayable sunscreen cosmetic contains substantially no ultraviolet ray scattering agents which cause whiteness, and which is transparent immediately after being applied/sprayed, and that has excellent ultraviolet ray protection effect and a good sensation in use. The ultraviolet ray protection effect is not reduced, and the effects improve when in contact with water. A water-in-oil emulsified sunscreen cosmetic comprises: (A) 6 to 40 mass % of an ultraviolet ray absorbing agent; (B) an organically modified clay mineral; (C) an oil phase thickener other than the aforementioned (B); (D) a silicone-based surfactant having an HLB of less than 8; (E) a spherical resin powder; and (F) a volatile silicone oil; wherein a ratio defined as [total amount of ingredient (B) and ingredient (C)]/[total amount of (G) non-volatile liquid oils other than silicone oils] is at least 0.04 and less than 0.68.
