Abstract:
1. An oil-in-water emulsified sunscreen cosmetic that satisfies all of the following conditions (A), (B), (C), (D), (E), and (G): (A) contains the following three surfactants (A-1)-(A-3) in an amount of 1-6 wt % of the total amount of the cosmetic: (B) contains the following oil soluble ultraviolet absorbent, which is solid at room temperature, in an amount of 0.01-5 wt % of the total amount of the cosmetic: bis-ethylhexyloxyphenolmethoxyphenyltriazine and/or tert-butylmethoxybenzoylmethane; (C) contains the following oil soluble ultraviolet absorbent, which is liquid at room temperature, in an amount of 1-14 wt % of the total amount of the cosmetic: ethylhexyl methoxycinnamate and/or octocrylene; (D) contains the following water soluble ultraviolet absorbent in an amount of 0.1-5 wt % of the total amount of the cosmetic: phenylbenzimidazolesulfonic acid; (E) contains higher alcohol having 14-24 carbon atoms which is present in an amount of 30-90 wt % of the total amount of ingredients (A-1), (A-2), and (A-3), and (G) contains a random copolymer ether compound of ethylene glycol and propylene glycol represented by the following formula (2) in an amount of 0.2-9 wt % of the total amount of the cosmetic: wherein AO denotes an oxyalkylene group having 3-4 carbon atoms, EO denotes an oxyethylene group, m and n, respectively, are average addition mole numbers of said oxyalkylene group and oxyethylene group; also 1=<m=<70 and 1=<n=<70; the ratio of the oxyethylene group to the total of the oxyalkylene group having 3-4 carbon atoms and the oxyethylene group being 50-100 wt %; the oxyalkylene group having 3-4 carbon atoms and the oxyethylene group being randomly added; R denotes a hydrocarbon group having 1-4 carbon atoms or hydrogen, each different or identical, and the ratio of the number of hydrogen atoms to the number of the hydrocarbon groups is 0.15 or less.
