Abstract
Abstract Detergent compositions comprising surfactant, at least one soluble detergency builder, and a plurality of rinse cycle suds control prills comprising fatty acid soap, quaternary ammonium salt, and silicone fluid suds suppressor. The granular detergent compositions of this invention provide control of the level of suds on the surface of the water and reduce the turbidity of the water during the rinse cycle without interfering with the level of suds on the surface of the water during the wash cycle of laundering operations.

Total Claims: 7
Claim 1
Independent Claim
146 words
A granular detergent composition providing reduced sudsing and rinse water turbidity during rinsing following a washing operation, said composition comprising: (a) at least one surfactant; (b) at least one soluble detergency builder; and (c) a plurality of rinse cycle suds control prills comprising: (i) fatty acid soap; (ii) at least one quaternary ammonium salt having at least one aliphatic hydrocarbon substituent containing from about 12 to about 18 carbon atoms; and (iii) at least one silicone fluid suds suppressor; wherein said prills comprise from about 0.1% to about 14% by weight said silicone fluid, wherein said prills comprise from about 5% to about 55% by weight said soap, wherein the mole ratio of said soap to said quaternary ammonium salt in said prills is from about 0.1:1 to about 4:1, and wherein said composition comprises from about 1% to about 20% by weight of said prills.
Claim 2
Dependent Claim
