PROBLEM TO BE SOLVED: To provide a liposome for cosmetic, providing smooth touch feeling without sticky feeling, having excellent stability and moist-keeping properties, and further having excellent properties to be formulated with alcohols and various kinds of surfactants which are often formulated with the cosmetic in general, and to provide the cosmetic.SOLUTION: The liposome for the cosmetic includes 10-50 pts.mass of component B, 0.1-5 pts.mass of component C, and 5-50 pts.mass of component D and 100 pts.mass of component A, and has an average particle diameter of 50-500 nm. Component A is a hydrogenated soybean phospholipid having &ge90 mass% of the content of phosphatidylcholine component B is cholesterol component C is N-acylamino acid salt component D is a copolymer of 2-methacryloyloxyethyl phosphorylcholine (MPC) and butyl methacrylate (BMA) in a molar ratio (MPC/BMA) of from 9/1 to 3/7. The liposome can stably be formulated even with a cosmetic having low viscosity and milky lotion.COPYRIGHT: (C)2012,JPO&INPIT【課題】べたつき感がなく、なめらかな感触が得られ、安定性、並びに保湿性に優れ、しかも、一般に化粧料に配合されることが多いアルコールや各種界面活性剤との配合性にも優れる、化粧料用リポソーム及び化粧料を提供すること。【解決手段】本発明の化粧料用リポソームは、A成分100質量部に対して、B成分10~50質量部、C成分0.1~5質量部およびD成分5~50質量部を含有し、平均粒径が50~500 nmであることを特徴とし、粘度の低い化粧料や乳液にも安定して配合できる。A.ホスファチジルコリン含量90質量%以上である水素添加大豆リン脂質、B.コレステロール、C.N-アシルアミノ酸塩、D.2-メタクリロイルオキシエチルホスホリルコリン(MPC)とブチルメタクリレート(BMA)のモル比(MPC/BMA)が9/1~3/7である共重合体。【選択図】なし
