PROBLEM TO BE SOLVED: To provide a water-in-oil emulsified-type cosmetic made by emulsification using an emulsifier, particularly with a silicone-containing oil emulsified, and improved in emulsion stability.SOLUTION: The emulsified-type cosmetic emulsified with an emulsifier is provided. This cosmetic is such as to be compounded with hydrophilic-and-hydrophobic anisotropic plate-like particles comprising such plate-like acrylic polymer particles that, when the contact angles of the respective one surface A and the other surface B with water at 20°C are measured, the contact angle difference between both the surfaces is &ge15°. This type of cosmetic, which is obtained by emulsifying a silicone oil-containing oil with a silicone-based surfactant, is suitable to its emulsion stability. In this cosmetic, the hydrophilic-and-hydrophobic anisotropic plate-like particles include such plate-like particles of an acrylic copolymer where the hydrophilic groups are arranged on the one surface and hydrophobic groups arranged on the other surface, or of a mixture of such acrylic copolymers.COPYRIGHT: (C)2011,JPO&INPIT【課題】本発明は、乳化剤を用いて乳化させた乳化型化粧料、特にシリコーンを含む油剤を乳化させた油中水型乳化化粧料について、その乳化安定性を向上させた乳化型化粧料を提供することを目的とする。【解決手段】乳化剤を用いて乳化した乳化型化粧料において、一方の面Aと他方の面Bのそれぞれの面について、20℃の水との接触角を測定したとき、両者の接触角の角度差が15度以上ある板状アクリル系重合体板状粒子からなる親疎水異方性板状粒子を配合した乳化型化粧料である。シリコーン油を含む油剤をシリコーン系界面活性剤で乳化させてなる乳化型化粧料の乳化安定性向上に適する。親疎水異方性板状粒子は、一方の表面に親水性基が配列し、他方の表面に疎水性基が配列したアクリル系共重合体或いはアクリル系共重合体混合物の板状粒子などである。【選択図】図1
