PROBLEM TO BE SOLVED: To obtain an O/W type emulsion which has high moisture retention though stickiness is suppressed, and is stable, has good sense of use and has low viscosity even if a water-soluble ascorbic acid derivative and its salt are blended therein.SOLUTION: The O/W type emulsion is obtained by blending an oil phase, an aqueous phase including one or more substances selected from a water-soluble ascorbic acid derivative and its salt, and one or more phospholipids selected from a lysophospholipid and a hydroxylated phospholipid, wherein a particle diameter is ≤500 nm.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明の目的は、べたつきを抑えたにも関わらず、保湿性が高く、水溶性アスコルビン酸誘導体およびその塩を配合しても安定で使用感のよい低粘度のO/W型エマルジョンを得ること【解決手段】油相と、水溶性アスコルビン酸誘導体およびその塩から選ばれる1種以上の物質を含む水相と、リゾリン脂質、水酸化リン脂質から選択される1種以上のリン脂質とを配合した、粒子径が500nm以下のO/W型エマルジョン【選択図】なし
