Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
43 words
A water-soluble detergent composition capable of inhibiting overglaze attack consisting essentially of about 50-95% by weight of at least one water-soluble inorganic or organic builder salt and about 0.5-3.0% by weight of aluminum silicate, said aluminum silicate having a pH of about 5-9.
Claim 2
Dependent Claim
43 words
A water-soluble detergent composition capable of inhibiting overglaze attack consisting essentially of about 50-95% by weight of at least one water-soluble inorganic or organic builder salt and about 0.5-3.0% by weight of aluminum silicate, said aluminum silicate having a pH of about 5-9.
Claim 3
Dependent Claim
29 words
A composition in accordance with claim 1 which also includes about 0.5% to 5% by weight of a water soluble bleaching agent capable of liberating hypohalite in aqueous media.
Claim 4
Dependent Claim
33 words
A composition in accordance with claim 2, which also includes about 0.5% to 5% by weight of water soluble organic detergent selected from the group consisting of non-ionic, anionic, cationic and amphoteric detergents.
Claim 5
Dependent Claim
30 words
A composition in accordance with claim 1 wherein the inorganic builder comprises about 55-75% by weight of sodium tripolyphosphate hexahydrate and about 15-25% by weight of weight of sodium metasilicate.
Claim 6
Dependent Claim
28 words
A composition in accordance with claim 1 wherein the builder salt is selected from the group consisting of alkalimetal phosphates, silicates, carbonates, sulfates and salts of organic acids.
Claim 7
Dependent Claim
38 words
A method for treating glasses, dishes and like glazed surfaces to remove foreign bodies from the surfaces thereof without modifying the substrata comprising treating said substrata with a dilute aqueous solution of the composition defined in claim 1.
Claim 8
Dependent Claim
13 words
A method in accordance with claim 6, which also includes a rinsing step.
Claim 9
Dependent Claim
