PROBLEM TO BE SOLVED: To obtain an oil-in-water emulsified cosmetic giving refreshing and comfortable feeling, and excellent in waterproofness, etc., by including a fluorine- based oil agent, powder treated with a fluorine compound and a specific water- soluble polysaccharide derivative so as to stably disperse both the oil agent aid powder in water. SOLUTION: This oil-in-water emulsified cosmetic is obtained by including (A) 1 to 50 wt.% of a fluorine-based oil agent, (B) 1 to 50 wt.% of powder treated with a fluorine compound and (C) 0.01 to 10 wt.% of a water-soluble polysaccharide derivative having both hydrophobic group and hydrophilic group; wherein the component C is preferably such one as to have >=8C hydrocarbon group, e.g. a derivative wherein at least part of the hydrogen atoms in the OH groups of a polysaccharide (derivative) is substituted with (i) substituent(s) having a hydraphobic group selected from a 8-40C alkyl group, alkenyl group, arylalkyl group and alkylaryl group and (ii) a substitent(s) having (OH substituted) (non)ionic hydrophilic parts, and the substitution degree ratio of the substituent i to the substituent ii is (1:100) to (100:1).
