PROBLEM TO BE SOLVED: To provide a formulation for improving silicone elastomer dispersibility (stability), which can be applied to a broad range of oil-in-water emulsion bases.SOLUTION: The oil-in-water emulsion skin preparation for external use is characterized by including the following components (a) to (d): (a) water-soluble thickener having a hydrophobic group, (b) a non-ionic surfactant having an HLB of 14 or higher, (c) a polyether modified silicone having an HLB of 3-5, and (d) a non-emulsifying crosslinked silicone. The non-emulsifying crosslinked silicone (d) is preferably formulated in the form of a swollen product swollen in an oil that is liquid at ordinary temperature, and the viscosity of the composition as a whole is preferably 30,000 mPa s or lower.COPYRIGHT: (C)2013,JPO&INPIT【課題】広範な水中油型エマルション基剤に適用することができる、シリコーンエラストマー分散性(安定性)を向上させる処方の提供。【解決手段】以下の成分(a)~(d):(a)疎水基を持つ水溶性増粘剤、(b)14以上のHLBを持つ非イオン性界面活性剤、(c)3~5のHLBを持つポリエーテル変性シリコーン、及び(d)非乳化性の架橋型シリコーンを含有することを特徴とする水中油型乳化皮膚外用剤。(d)非乳化性架橋型シリコーンは、常温で液状の油分で膨潤した膨潤物の形態で配合するのが好ましく、組成物全体の粘度を30000mPa・s以下とするのが好ましい。【選択図】なし
