Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 54 words
DETERGENT COMPOSITION IN SUBSTANTIALLY DRY FORM CONSISTING ESSENTIALLY OF AN ORGANIC DETERGENT SELECTED FROM THE GROUP CONSISTING OF ANIONIC, CATIONIC, NONIONIC AND AMPHOTERIC SURFACE ACTIVE COMPOUNDS, A FILLER SELECTED FROM THE GROUP CONSISTING OF SODIUM SULFATE AND SODIUM CARBONATE AND, IN COMBINATION THEREWITH AS A BUILDER, A COMPOUND SELECTED FROM THE GROUP CONSISTING OF
Claim 2
Dependent Claim 54 words
DETERGENT COMPOSITION IN SUBSTANTIALLY DRY FORM CONSISTING ESSENTIALLY OF AN ORGANIC DETERGENT SELECTED FROM THE GROUP CONSISTING OF ANIONIC, CATIONIC, NONIONIC AND AMPHOTERIC SURFACE ACTIVE COMPOUNDS, A FILLER SELECTED FROM THE GROUP CONSISTING OF SODIUM SULFATE AND SODIUM CARBONATE AND, IN COMBINATION THEREWITH AS A BUILDER, A COMPOUND SELECTED FROM THE GROUP CONSISTING OF
Claim 3
Dependent Claim 25 words
The detergent composition of claim 1, wherein the proportion of builder ranges from 20 to 60% based on the weight of total detergent composition solids.
Claim 4
Dependent Claim 46 words
The detergent composition of claim 1 wherein there is also present, in a proportion up to 55% based on the weight of total detergent composition solids, a supplemental builder selected from the group consisting of alkali metal polyphosphates and aminopolycarboxylic acids and salts, and mixtures thereof.
Claim 5
Dependent Claim 16 words
The detergent composition of claim 1, wherein said builder is the sodium salt of 7-oxabicyclo(2.2.1)hept-5-ene-2,3-dicarboxylic acid.
Claim 6
Dependent Claim 48 words
A detergent composition in a substantially dry form consisting essentially of an organic detergent selected from the group consisting of anionic, cationic, non-ionic and amphoteric surface active compounds, a water-soluble alkali metal silicate and, in combination therewith as a builder, a compound selected from the group consisting of
Claim 7
Dependent Claim 48 words
A detergent composition in a substantially dry form consisting essentially of an organic detergent selected from the group consisting of anionic, cationic, non-ionic and amphoteric surface active compounds, a water-soluble alkali metal silicate and, in combination therewith as a builder, a compound selected from the group consisting of
Claim 8
Dependent Claim 78 words
A process for removing soil from a fabric which comprises washing said fabric in an aqueous medium having a pH of about 8 to 13 containing from about 0.05 to 0.25%, based on the weight of wash water, of a detergent composition consisting essentially of a synthetic organic detergent selected from the group consisting of anionic, cationic, non-ionic and amphoteric surface active compounds and, in solution therewith as a builder, a compound selected from the group consisting of
Claim 9
Dependent Claim 78 words
A process for removing soil from a fabric which comprises washing said fabric in an aqueous medium having a pH of about 8 to 13 containing from about 0.05 to 0.25%, based on the weight of wash water, of a detergent composition consisting essentially of a synthetic organic detergent selected from the group consisting of anionic, cationic, non-ionic and amphoteric surface active compounds and, in solution therewith as a builder, a compound selected from the group consisting of
Claim 10
Dependent Claim 24 words
The process of claim 6, wherein the proportion of builder ranges from 20 to 60% based on the weight of total detergent composition solids.
Claim 11
Dependent Claim 44 words
The process of claim 7, wherein there is present, in a proportion up to 55% based on the weight of total detergent composition solids, a supplemental builder selected from the group consisting of alkali metal polyphosphates and aminopolycarboxylic acids and salts, and mixtures thereof.
Claim 12
Dependent Claim 52 words
The prOcess of claim 7, wherein there is also present, in a proportion of from 2 to 12%, a water-soluble alkali metal silicate and, in a proportion up to about 45%, a filler selected from sodium sulfate and sodium carbonate, each proportion being based on the weight of total detergent composition solids.
