Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 209 words
A non-corrosive detergent composition for cleaning automotive surfaces, comprising: 1 to 10 weight percent of a neutral sequestering agent for reacting with metal ions contained in the composition, said neutral sequestering agent comprising an alkali metal condensed phosphate; 1 to 10 weight percent of a wetting agent selected from the group consisting of alkali metal salts of fatty acid sulfates and sulphonates having from 8 to 18 carbons in the fatty acid group, lower alkylbenzene sulfonates having from 1 to 3 carbons in the lower alkyl group, and ethylhexylalcoholsulfate; 1 to 10 weight percent of a surfactant selected from the group consisting of polyoxyethylated sulfates and sulfonates and polyoxyethylated nonyl, octyl and isooctyl phenols; 0.5 to 5 weight percent of a penetrant for penetrating a dirt film on the surface to be cleaned, said penetrant being selected from the group consisting of propylene glycol, propylene glycol monomethyl ether, dipropylene glycol monomethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol monopropyl ether and mixtures thereof; 0.1 to 6 weight percent of a foam booster for providing a foaming action upon application of the composition on a surface comprising a fatty acid amide; and the balance an aqueous carrier, said composition having a pH in the neutral range.
Claim 2
Dependent Claim 209 words
A non-corrosive detergent composition for cleaning automotive surfaces, comprising: 1 to 10 weight percent of a neutral sequestering agent for reacting with metal ions contained in the composition, said neutral sequestering agent comprising an alkali metal condensed phosphate; 1 to 10 weight percent of a wetting agent selected from the group consisting of alkali metal salts of fatty acid sulfates and sulphonates having from 8 to 18 carbons in the fatty acid group, lower alkylbenzene sulfonates having from 1 to 3 carbons in the lower alkyl group, and ethylhexylalcoholsulfate; 1 to 10 weight percent of a surfactant selected from the group consisting of polyoxyethylated sulfates and sulfonates and polyoxyethylated nonyl, octyl and isooctyl phenols; 0.5 to 5 weight percent of a penetrant for penetrating a dirt film on the surface to be cleaned, said penetrant being selected from the group consisting of propylene glycol, propylene glycol monomethyl ether, dipropylene glycol monomethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol monopropyl ether and mixtures thereof; 0.1 to 6 weight percent of a foam booster for providing a foaming action upon application of the composition on a surface comprising a fatty acid amide; and the balance an aqueous carrier, said composition having a pH in the neutral range.
Claim 3
Dependent Claim 13 words
A composition according to claim 1 wherein the sequestering agent is potassium tripolyphosphate.
Claim 4
Dependent Claim 12 words
A composition according to claim 1 wherein the wetting agent is ethylhexylalcoholsulfate.
Claim 5
Dependent Claim 16 words
A composition according to claim 1 wherein the penetrant is a propylene glycol alkyl ether derivative.
Claim 6
Dependent Claim 27 words
A composition according to claim 1, wherein the penetrant is selected from the group consisting of propylene glycol monomethyl ether, dipropylene glycol monomethyl ether, and mixtures thereof.
Claim 7
Dependent Claim 17 words
A composition according to claim 1 which further contains 0.01 to 0.10 weight percent of a perfume.
Claim 8
Dependent Claim 24 words
A composition according to claim 1 wherein the composition further contains a water soluble dye in an amount from 0.001 to 0.10 weight percent.
Claim 9
Dependent Claim 15 words
A composition according to claim 7 wherein the water soluble dye is an optical brightener.
Claim 10
Dependent Claim 12 words
A composition according to claim 1 wherein the aqueous carrier is water.
Claim 11
Dependent Claim 40 words
A detergent composition according to claim 1, comprising 3-6 wt. percent of said neutral sequestering agent, 3-6 wt. percent of said wetting agent, 3-6 wt. percent of said surfactant, 1-4 wt. percent of said penetrant and 78-90 wt. percent water.
Claim 12
Dependent Claim 18 words
An article of manufacture comprising an aerosol can containing the detergent composition of claim 1 and a propellant.
Claim 13
Dependent Claim 74 words
A detergent composition comprising: deionized water; potassium tripolyphosphate; 2-ethylhexylalcoholsulfate; a polyoxyethylated surfactant selected from the group consisting of polyoxyethylated nonyl, octyl and isooctyl phenols; a penetrant selected from the group consisting of propylene glycol, dipropylene glycol monomethyl ether, propylene glycol monomethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutylether, ethylene glycol monopropyl ether and mixtures thereof; coconut fatty acid diethanolamide; perfume; and water soluble dye, said composition having a pH in the neutral range.
Claim 14
Dependent Claim 74 words
A detergent composition comprising: deionized water; potassium tripolyphosphate; 2-ethylhexylalcoholsulfate; a polyoxyethylated surfactant selected from the group consisting of polyoxyethylated nonyl, octyl and isooctyl phenols; a penetrant selected from the group consisting of propylene glycol, dipropylene glycol monomethyl ether, propylene glycol monomethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutylether, ethylene glycol monopropyl ether and mixtures thereof; coconut fatty acid diethanolamide; perfume; and water soluble dye, said composition having a pH in the neutral range.
