Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
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.
Claim 2
Dependent Claim
90 words
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.
Claim 3
Dependent Claim
13 words
The composition of claim 1, wherein said hydrate forming salt is magnesium sulfate.
Claim 4
Dependent Claim
26 words
The composition of claim 1, wherein said buffer comprises at least one of a citric acid salt, a maleic acid salt, and a phosphoric acid salt.
Claim 5
Dependent Claim
27 words
The composition of claim 3, wherein said buffer comprises a mixture of about 0.5% of a citric acid salt and about 1.0% of a phosphoric acid salt.
Claim 6
Dependent Claim
14 words
The composition of claim 4, wherein said buffer comprises disodium phosphate and trisodium citrate.
Claim 7
Dependent Claim
22 words
The composition of claim 1, wherein an alkyl chain in the alcohol ether sulfate has from about 12 to 15 carbon atoms.
Claim 8
Independent Claim
98 words
A method for forming a hollow bead detergent composition comprising spray drying a composition comprising by weight, about 5-12% of an alcohol ether sulfate, about 5-15% of magnesium sulfate, and about 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.
Claim 9
Independent Claim
98 words
A method for forming a hollow bead detergent composition comprising spray drying a composition comprising by weight, about 5-12% of an alcohol ether sulfate, about 5-15% of magnesium sulfate, and about 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.
