Publication number: 20210386652Abstract: The purpose of the present invention is to provide an oil-in-water emulsion cosmetic that is thickened using an associative thickener containing a hydrophobic modified polyether urethane, that stably holds a hydrophobization powder in an inner oil phase, and that does not release water even after long-term storage, without a reduction in usage sensations regarding moistness, resilience, and smoothness originally possessed by the oil-in-water emulsion cosmetic. The present invention is an oil-in-water emulsion cosmetic characterized by comprising (A) a hydrophobic modified polyether urethane having a specific structure such as polyurethane-59, (B) a polyether modified silicone having an HLB (Si) of 5-14, and (C) a hydrophobization powder. The cosmetic according to the present invention preferably further comprises (D) a lower alcohol and/or a polyol, and/or (E) a nonionic surfactant having an HLB of 8-18.Type: ApplicationFiled: October 10, 2019Publication date: December 16, 2021Applicant: Shiseido Company, Ltd.Inventors: Yuko NAGARE, Mayuri TASHIRO
