Abstract
Abstract Granular detergent compositions having an effective suds controlling agent comprising a suds-controlling silicone material which is substantially removed from contact with the surfactant component or alkaline component of the composition by incorporation in, e.g., a polyethylene glycol carrier, with preferably a small amount of fatty acid, in an irregularly shaped particle having a minimum dimension of at least about 0.05 cm. and being substantially free of water soluble inorganic salts.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
A granular detergent composition comprising: (a) a suds suppressing amount of a stable suds controlling component especially adapted for use in a detergent composition, comprising a silicone suds controlling agent having an average droplet diameter of from about 1 to about 50 microns releasably incorporated in a water-soluble or water dispersible, substantially non-surface active, detergent-impermeable, and non-hygroscopic carrier, said component being substantially free of water-soluble relatively hygroscopic inorganic salts and in the form of an irregularly shaped particle having a minimum dimension of not less than about 0.05 cm and the maximum dimension being at least about 20% greater than the minimum dimension; and (b) a sudsing detergent component selected from the group consisting of anionic, nonionic, zwitterionic, ampholytic, and cationic detergents and mixtures thereof.
Claim 2
Dependent Claim
125 words
A granular detergent composition comprising: (a) a suds suppressing amount of a stable suds controlling component especially adapted for use in a detergent composition, comprising a silicone suds controlling agent having an average droplet diameter of from about 1 to about 50 microns releasably incorporated in a water-soluble or water dispersible, substantially non-surface active, detergent-impermeable, and non-hygroscopic carrier, said component being substantially free of water-soluble relatively hygroscopic inorganic salts and in the form of an irregularly shaped particle having a minimum dimension of not less than about 0.05 cm and the maximum dimension being at least about 20% greater than the minimum dimension; and (b) a sudsing detergent component selected from the group consisting of anionic, nonionic, zwitterionic, ampholytic, and cationic detergents and mixtures thereof.
Claim 3
Dependent Claim
45 words
The composition of claim 1 in which there is from about 10% to about 50% of said detergent component and from 0.005% to about 10% of the silicone suds controlling agent in a carrier at a greater than about 2:1 ratio of carrier to silicone.
Claim 4
Dependent Claim
58 words
The composition of claim 2 in which said droplet diameter is from about 5 to about 30 microns; there is from about 10% to about 30% detergent component; and from about 0.01% to about 0.5% silicone suds controlling agent in a polyethylene glycol carrier at a ratio of carrier to silicone of from about 5:1 to about 100:1.
Claim 5
Dependent Claim
46 words
A composition according to claim 3 wherein the detergent compound comprises a water-soluble salt of an organic sulfuric reaction product having in its molecular structure an alkyl group containing from about 8 to about 22 carbon atoms and a sulfonic acid or sulfuric acid ester group.
Claim 6
Dependent Claim
102 words
A composition according to claim 3 wherein the detergent compound is selected from the group consisting of sodium linear C 10 -C 13 alkylbenzene sulfonate; sodium C 10 -C 18 alkyl sulfate; the sodium salt of a sulfated condensation product of a C 10 -C 18 alcohol with from about 1 to about 3 moles of ethylene oxide; the condensation product of a C 10 -C 18 fatty alcohol with from about 4 to about 10 moles of ethylene oxide; the water-soluble sodium and potassium salts of higher fatty acids containing from about 10 to about 18 carbon atoms; and mixtures thereof.
Claim 7
Dependent Claim
24 words
A composition according to claim 5 containing, as an additional component, from about 5% to about 95% by weight of a water-soluble detergency builder.
Claim 8
Dependent Claim
33 words
A composition according to claim 6 wherein there is from about 10% to about 50% of said detergency auxiliary builder which is selected from the group consisting of sodium tripolyphosphate and potassium tripolyphosphate.
Claim 9
Dependent Claim
30 words
A composition according to claim 6 wherein the detergency builder is selected from the group consisting of sodium carbonate, sodium bicarbonate, sodium silicate, sodium citrate, sodium nitrilotriacetate, and mixtures thereof.
Claim 10
Dependent Claim
83 words
The composition of claim 1 in which said droplet diameter is from about 1 to about 50 microns; there is from about 10% to about 50% detergent component; and from about 0.01% to about 0.5% silicone suds controlling agent in a polyethylene glycol carrier at a ratio of carrier to silicone of from about 5:1 to about 100:1, and in which the carrier also comprises from about 0.2% to about 15% of fatty acids containing from about 12 to about 30 carbon atoms.
Claim 11
Dependent Claim
28 words
The composition of claim 9 in which the carrier comprises from about 0.25% to about 2% of fatty acids containing from about 14 to about 20 carbon atoms.
Claim 12
Dependent Claim
46 words
A composition according to claim 9 wherein the detergent compound comprises a water-soluble salt of an organic sulfuric reaction product having in its molecular structure an alkyl group containing from about 8 to about 22 carbon atoms and a sulfonic acid or sulfuric acid ester group.
Claim 13
Dependent Claim
