Abstract: The present invention provides an oil-in-water emulsion composition thickened with a hydrophobically modified polyether urethane, the composition having improved high-temperature stability and giving a pudding-like unique feeling. The invention provides an elastic jelly-like composition characterized in that a hydrophobically modified polyether urethane has been incorporated into an oil-in-water emulsion including oil droplets with an average particle diameter of 150 nm or smaller. The elastic jelly-like composition is transparent or translucent, gives a pudding-like elastic feeling, has excellent viscosity stability at high temperatures, and is suitable for use as a cosmetic-preparation base. The hydrophobically modified polyether urethane is especially preferably a PEG-240/decyltetradeceth-20/HDI copolymer.

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: 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.
