Abstract: An oil-in-water emulsified sunblock cosmetic has excellent feeling when used and maintains a high ultraviolet-ray protective effect even upon contact with water or sweat. The oil-in-water emulsified sunblock cosmetic contains an (A) ultraviolet-ray protective agent and a (B) fatty acid forming a solid at room temperature, the cosmetic is characterized in that 51% or less of the fatty acid is neutralized, and the formulation ratio ((A)/(B) of the (A) ultraviolet-ray protective agent to the (B) fatty acid is in the range of at least 0.1 and less than 10.0. The cosmetic exhibits the unprecedented and surprising property of contact with water causing an improvement to the ultraviolet-ray protective ability. It is preferable for the cosmetic to contain an (C) oily component having IOB of 0.5 or higher.

Abstract: A sprayable sunscreen cosmetic contains substantially no ultraviolet ray scattering agents which cause whiteness, and which is transparent immediately after being applied/sprayed, and that has excellent ultraviolet ray protection effect and a good sensation in use. The ultraviolet ray protection effect is not reduced, and the effects improve when in contact with water. A water-in-oil emulsified sunscreen cosmetic comprises: (A) 6 to 40 mass % of an ultraviolet ray absorbing agent; (B) an organically modified clay mineral; (C) an oil phase thickener other than the aforementioned (B); (D) a silicone-based surfactant having an HLB of less than 8; (E) a spherical resin powder; and (F) a volatile silicone oil; wherein a ratio defined as [total amount of ingredient (B) and ingredient (C)]/[total amount of (G) non-volatile liquid oils other than silicone oils] is at least 0.04 and less than 0.68.

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: To provide a second agent for a coating-type body corrective film formation agent that can shorten the cross-linking reaction time in film formation and improve the durability of the film to be obtained.
An oil-in-water composition of the present disclosure comprises a dispersion medium containing water, and oil droplets dispersed in this dispersion medium, wherein the oil droplets comprise an oil, and a catalyst that serves as a cross-linking ingredient, wherein the oil-in-water composition is used as a second agent for a coating-type body corrective film formation agent comprising a first agent comprising a cross-linking reactive ingredient that constitutes a body corrective film; and a second agent comprising a cross-linking ingredient for cross-linking the cross-linking reactive ingredient.
