Claims7
A spray dried hollow bead detergent composition comprising, by weight, about 5-12% of an alcohol ether sulfate;
- about 5-15% of magnesium sulfate;
- and 0.25-2.5% of a buffer selected from the group consisting of the salts of citric, maleic and phosphoric acid, and mixtures thereof;
- about 8-12% of sodium chloride and about 40-60% of a sodium or potassium sulfate filler, wherein an alkyl chain in the alcohol ether sulfate has from about 10 to 18 carbon atoms and wherein the alcohol ether sulfate has from about 3 to 7 ether groups.
