Abstract: A transparent composition having UV protection effect is provided, wherein the UV protection effect is improved after the composition is contacted with moisture, such as water or sweat, more than that immediately after the composition is applied, while maintaining high transparency. The transparent composition contains (a) a UV absorbent, (b) an oil component having a refractive index in the range from 1.5 to 1.7, (c) an oil component having a refractive index of not less than 1.3 and less than 1.5, and (d) a powder having a refractive index in the range from 1.45 to 1.55, wherein a mixed oil component obtained by mixing the (b) oil component having a refractive index in the range from 1.5 to 1.7 and the (C) oil component having a refractive index of not less than 1.3 and less than 1.5 has a refractive index in the range from 1.44 to 1.56.

Abstract: Provided is an oil-in-water type emulsified sunscreen cosmetic which contains (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. The oil-in-water type emulsified sunscreen cosmetic 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 or high temperatures, spreads and absorbs well when applied to the skin, does not cause stickiness following application and has a refreshing feel.
