Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 188 words
A detergent concentrate composition comprising: A. about 1.5-2.0% by weight of a non-ionic detergent which is a condensation product of about 8-16 moles of ethylene oxide with one mole of a compound selected from the group consisting of 1. an alkyl phenol having about 7-10 carbon atoms in the alkyl group; 2. an alkyl amine having about 12-16 carbon atoms in the alkyl group; and 3. an aliphatic alcohol having about 12-16 carbon atoms; B. about 0.25-0.30% by weight of an alkyl dimethyl amine oxide in which the alkyl group has about 12-16 carbon atoms; C. about 0.30-0.40% by weight of a quaternary ammonium halide having the formula ##STR2## where R 1 and R 2 are methyl; R 3 is methyl or a phenyl-substituted alkyl group having about 8-12 carbon atoms; and R 4 is an alkyl group having about 12-18 carbon atoms; D. about 5-5.8% by weight of an alkaline inorganic builder selected from the group consisting of the alkali metal carbonates, phosphates, and borates; and E. a defoaming agent in an amount effective to control foaming of the composition in use; and F. the remainder water.
Claim 2
Dependent Claim 188 words
A detergent concentrate composition comprising: A. about 1.5-2.0% by weight of a non-ionic detergent which is a condensation product of about 8-16 moles of ethylene oxide with one mole of a compound selected from the group consisting of 1. an alkyl phenol having about 7-10 carbon atoms in the alkyl group; 2. an alkyl amine having about 12-16 carbon atoms in the alkyl group; and 3. an aliphatic alcohol having about 12-16 carbon atoms; B. about 0.25-0.30% by weight of an alkyl dimethyl amine oxide in which the alkyl group has about 12-16 carbon atoms; C. about 0.30-0.40% by weight of a quaternary ammonium halide having the formula ##STR2## where R 1 and R 2 are methyl; R 3 is methyl or a phenyl-substituted alkyl group having about 8-12 carbon atoms; and R 4 is an alkyl group having about 12-18 carbon atoms; D. about 5-5.8% by weight of an alkaline inorganic builder selected from the group consisting of the alkali metal carbonates, phosphates, and borates; and E. a defoaming agent in an amount effective to control foaming of the composition in use; and F. the remainder water.
Claim 3
Dependent Claim 29 words
A composition in accordance with claim 1 in which said non-ionic detergent is the condensation product of one mole of octyl phenol with about 9-13 moles of ethylene oxide.
Claim 4
Dependent Claim 35 words
A composition in accordance with claim 1 in which said non-ionic detergent is the condensation product of one mole of an aliphatic alcohol having about 12-15 carbon atoms with about 9 moles of ethylene oxide.
Claim 5
Dependent Claim 27 words
A composition in accordance with claim 1 in which said builder is selected from the group consisting of tetrasodium pyrophosphate, sodium metasilicate, sodium carbonate, and mixtures thereof.
Claim 6
Dependent Claim 32 words
A liquid hard-surface detergent composition comprising an aqueous solution containing about 1 part by weight of the composition of claim 1 diluted with about 0.1 to 100 parts by weight of water.
Claim 7
Dependent Claim 21 words
The detergent concentrate composition of claim 1, wherein said composition comprises about 0.001 - 0.01% by weight of a defoaming agent.
