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.
