摘要： 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.

摘要： The present invention relates to a cosmetic having the innovative, unprecedented property in which the ultraviolet protection effects do not decrease, but conversely increase, due to coming into contact with moisture such as water or perspiration, and due to heat applied in the usage environment. The cosmetic of the present invention contains (A) an ultraviolet protectant; (B) at least one compound that is water-soluble and that has an IOB of 5.0 or lower, selected from among (i) alkylene oxide derivatives and (ii) polyhydric alcohols; and (C) an oil phase thickener; wherein the mass ratio of component (A)/component (B) is 20 or lower; and the (B) (i) alkylene oxide derivatives are polyoxyalkylene/polyoxyethylene copolymer dialkyl ethers represented by the following formula (I): R1O-[(AO)m(EO)n]-R2 (I) wherein R1 and R2, each independently, denote a hydrogen atom or a hydrocarbon group having one to four carbon atoms, AO denotes an oxyalkylene group having three or four carbon atoms, EO denotes an oxyethylene group, 1≤m≤70, 1≤n≤70 and m+n≤40.
