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 |
