PURPOSE:To stably disperse a zeolite to improve the storage stability by dissolving a specific polymeric material in an aqueous dispersion containing a surface active agent and the zeolite. CONSTITUTION:0.3-10wt.% polymeric material (e.g. an acrylate/methacrylate copolymer) which can dissolve homogeneously in an aqueous solution of a surface active agent containing a mixture (A) of an anionic surface active agent and a nonionic surface active agent in an amount of 20wt.% and has a thickening effect on an aqueous dispersion containing 20wt.% component (A) and 15wt.% zeolite (B) having a mean particle diameter of 5mum or below of the formula (wherein M is an alkali metal atom; M' is an alkaline earth metal atom replaceable with Ca; and x, y and w are respectively the numbers of moles of the components, x being 0.7-1.5, y being 1-3 and w being an arbitrary number) is homogeneously dissolved in an aqueous dispersion which contains 5-30wt.% component (A) and 5-25wt.% component (B). |
