    (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.

    Abstract: The purpose of the present invention is to newly provide a method with which it is possible to appropriately evaluate the protective effect of an external preparation for skin such as a sunscreen cosmetic, particularly to evaluate how a UV-ray protective effect is affected by heat. This evaluation method is characterized by including (1) a step for forming a coating film of an external preparation for skin on a substrate, (2) a step for heat-treating the coating film of the external preparation for skin, and (3) a step for measuring the UV-ray protective effect of the heat-treated coating film of the external preparation for skin. The heat treatment is preferably carried out for at least one minute at a temperature of 30-70° C. The step for measuring the UV-ray protective effect preferably includes at least one selected from testing methods that involve comparing some kind of UV-ray protective effect with SPF measurement, UVAPF or PFA measurement, critical wavelength measurement, absorbance measurement, and transmittance measurement. This evaluation method can also be performed in vivo or in vitro.

    Abstract: The purpose of the present invention is to provide an oil-in-water emulsion composition exhibiting high UV-protective capabilities with which it is possible to uniformly and stably disperse a hydrophobized metal oxide into an inner phase (oil phase) without detracting from the inherent fresh sensation on use of an oil-in-water emulsion composition even when a high amount of the hydrophobized metal oxide is compounded therewith. In summary, the present invention is an oil-in-water emulsion composition characterized by including (A) 0.1-5 mass % of polyether-modified silicone having an HLB (Si) of 5-14, (B) one or more hydrophilic thickeners, (C) a metal oxide hydrophobized by an agent other than metal soap, and (D) nonvolatile oil other than silicone oil, the (C) hydrophobized metal oxide being present in the inner phase.
