Abstract: A stable, homogeneous, aqueous detergent slurry is described containing polymeric acrylic stabilizers. The slurry contains about 14 weight percent to about 30 weight percent of a sodium polyphosphate, 0 to about 1 weight percent of sodium carboxymethylcellulose, 0 to about 5 weight percent of a compatible inorganic alkali metal hydroxide or salt as a viscosity modifier, a soluble nonionic surface-active agent in amounts of from about 13 weight percent to about 20 weight percent, a stabilizing amount ranging from about 0.4 to about 2 weight percent of a high molecular weight polymer of an acrylic acid, and wherein said sodium polyphosphate is present in part as insoluble particles having an average diameter of about 1 to about 10 microns.
