PROBLEM TO BE SOLVED: To provide a skin cleaner in the form of an aqueous solution where inorganic microballoon particles used as an abrasive do not float and also does not segregate in the aqueous solution.SOLUTION: The skin cleaner contains 5-20 mass% of a surfactant, 5-15 mass% of an oil remover, 0.1-0.5 mass% of an acrylic acid-methacrylic acid copolymer and 3-15 mass% of hydro-floatable inorganic microballoon particles for the purpose of stably dispersing the inorganic microballoon particles such as Shirasu balloons in the aqueous solution for a long period. In this skin cleanser, the copolymer exhibits excellent dispersion-stabilizing effect and does not hinder the spreadability of the cleaner.COPYRIGHT: (C)2008,JPO&INPIT【課題】研磨剤として使用する無機中空体粒子が、水溶液中で浮上分離しない皮膚用洗浄剤を提供する。【解決手段】シラスバルーン等の水浮上性無機中空体粒子が水溶液中において長期間安定に分散するため、界面活性剤が5~20質量%、油除去剤が5~15質量%、アクリル酸-メタクリル酸共重合体が0.1~0.5質量%、水浮上性無機中空体粒子が3~15質量%含有される皮膚用洗浄剤。上記共重合体は少量で優れた分散安定効果を示し、また洗浄剤の展延性を阻害しない。【選択図】なし
