PROBLEM TO BE SOLVED: To provide an oil-in-water type emulsified sunscreen cosmetic that undergoes little change in viscosity even if a large quantity of an ultraviolet radiation absorber is blended in the cosmetic and even when stored for long periods at low (0°C) or high (50°C) temperatures, spreads and absorbs well when applied to the skin, does not cause stickiness following application and has a refreshing feel.SOLUTION: The oil-in-water type emulsified sunscreen cosmetic includes (a) 0.1 to 5.0 mass% of an organosiloxane derivative represented by general formula (1) (in the formula, at least one of R1 to R3 is a functional group represented by -O-Si(R4)3 (R4 is an alkyl group having 1 to 6 carbon atoms or a phenyl group), and the remaining R1 to R3 groups may be the same or different and are substituted or unsubstituted monovalent hydrocarbon groups, M is a hydrogen atom, a metal atom or an organic cation, and A is a straight chain or branched chain alkylene group represented by CqH2q, wherein q is an integer of 0 to 20), (b) 0.1 to 5.0 mass% of poly(ethylene glycol) stearate, (c) 10.0 to 25.0 mass% of an ultraviolet radiation absorber and (d) a higher alcohol.COPYRIGHT: (C)2013,JPO&INPIT【課題】紫外線吸収剤を高配合しているにも関わらず、低温(0℃)および高温(50℃)で長時間保管されても粘度変化が小さく、しかも皮膚に塗布する際に伸びやなじみが良く、塗布後にべたつかず、さっぱりとした感触を有する、水中油型乳化日焼け止め化粧料の提供。【解決手段】(a)オルガノシロキサン誘導体を0.1~5.0質量%、(b)ステアリン酸ポリエチレングリコールを0.1~5.0質量%、(c)紫外線吸収剤を10.0~25.0質量%、および(d)高級アルコールを含有し、前記(a)オルガノシロキサン誘導体は以下の一般式で示される。【選択図】なし
