PROBLEM TO BE SOLVED: To solve problems in the case of resins such as candelilla resins and resin acid derivatives, and polymer liquidity hydrocarbons such as heavy isoparaffin and polybutene, which are oil-soluble raw materials conventionally used to improve cosmetic effects, since they are strongly sticky, they provide bad feeling and cause restrictions on blending amounts, and since they have bad extensibility (spreading) on the skin, sufficient cosmetic sustaining effects cannot be obtained in the case of hydrocarbon waxes and vegetable and animal waxes, since they are solidified during normal temperatures, and amounts used are significantly restricted in liquid prescription, sufficient effects cannot be obtained, and since they provide greasy use feeling, sense of touch is deteriorated.SOLUTION: A cosmetic is obtained by blending copolymers obtained by polymerizing three sorts of monomers, that is, acrylic acid, methacrylate isobornyl and methacrylate isobutyl, which are oil-soluble resins.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】化粧効果を向上させるために従来使用される油溶性原料であるキャンデリラ樹脂やロジン酸誘導体の樹脂類、重質イソパラフィン、ポリブテン等の高分子流動性炭化水素類は、べたつきが強いため感触が悪く配合量に制約が生じ、皮膚上での展開性(伸び)も悪いため、十分な化粧持続性効果を得られない、また、炭化水素系ワックス類、植物性動物性ロウ類においては、常温時において固化することから液状の処方においては著しく使用量が制限され、十分な効果が得られない、また、使用感も脂っぽく、感触を悪くする原因となるなどの問題があった。【解決手段】油溶解性樹脂であるアクリル酸、メタクリル酸イソボルニル、メタクリル酸イソブチルの三種の単量体を重合して得られるコポリマーを配合することにより得られる化粧料【選択図】なし
