Low phosphate content detergent composition

Claim 1

A spray dried granular detergent composition consisting essentially of: a. from 10% to 18% water-soluble phosphate builder salt selected from the group consisting of alkali metal pyrophosphate and alkali metal tripolyphosphate; b. at least about 3% of a condensation product of an alcohol having from about 8 to about 18 carbon atoms with from about 3 to about 15 moles of ethylene oxide per mole of alcohol; c. from about 1% to about 2% ethylene oxide condensation product wherein said condensation product has an average molecular weight of from about 2,500 to about 20,000; d. from about 1% to about 2% water-soluble maleic anhydride - vinyl methyl ether copolymer having a molecular weight of from about 10,000 to about 350,000 and water-soluble salts thereof; e. water-soluble salt of linear alkyl benzene sulfonate wherein the alkyl radical contains from 10 to 15 carbon atoms, the total level of linear alkyl benzene sulfonate and said condensation product of alcohol and ethylene oxide being less than about 30% and the weight ratio of linear alkyl benzene sulfonate to said condensation product of alcohol and ethylene oxide being from about 3:1 to about 1:1; f. from 1% to 15% sodium silicate having a SiO 2 : Na 2 O ratio of from 3:1 to 1.5:1; g. from 5% to 40% sodium sulfate; and h. from 5% to 35% peroxy bleach.
