PROBLEM TO BE SOLVED: 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.SOLUTION: 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) an alcohol and/or a polyol, and/or (E) a nonionic surfactant having an HLB of 8-18. (C) the hydrophobization powder is preferably a metal oxide powder treated with triethoxycaprylylsilane, dimethicone, hydrogen dimethicone, or a metallic soap.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】疎水変性ポリエーテルウレタンからなる会合性増粘剤で増粘した水中油型乳化組成物が元来有しているみずみずしく弾力のある滑らかな使用感を損なうことなく、疎水化処理粉末を内油相中に安定に保持し、長期保管しても離水を生じない水中油型乳化組成物の提供。【解決手段】（Ａ）ポリウレタン－５９等の特定構造の疎水変性ポリエーテルウレタン、（Ｂ）ＨＬＢ（Ｓｉ）が５～１４のポリエーテル変性シリコーン、及び（Ｃ）疎水化処理粉末を含有することを特徴とする水中油型乳化化粧料。本発明の化粧料は、（Ｄ）アルコール及び／又はポリオール、及び／又は（Ｅ）ＨＬＢ＝８～１８の非イオン性界面活性剤を更に含有するのが好ましい。前記（Ｃ）疎水性処理粉末は、トリエトキシカプリリルシラン、ジメチコン、ハイドロゲンジメチコン、又は金属石鹸で処理された金属酸化物粉末であるのが好ましい。【選択図】なし
