Abstract

Abstract A liquid hard surface cleaner is disclosed that is impalpable, self-opacifying, enjoys low temperature stability and has satisfactory viscosity and detergency, these being achieved by a particular combination of ingredients and proportions; namely, the composition comprising, by weight, a water-soluble, synthetic, anionic, sulphated or sulphonated detergent salt containing an alkyl radical of 8 to 22 carbon atoms in the molecule, a water-soluble alkylene oxylated nonionic detergent, a water-soluble detergent builder salt and the balance water, the weight ratio of anionic detergent to nonionic detergent being from 0:5 to 6:1 and the weight ratio of builder salt to total detergent being in the range of 1:5 to 5:1.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 195 words
A self-opacified, impalpable, homogeneous, liquid, hard surface cleaner consisting essentially of, by weight, from 2% to 6% of a water-soluble, synthetic, anionic, sulfated or sulfonated detergent salt containing an alkyl radical of 8 to 22 carbon atoms in the molecule, said salt being selected from the group consisting of ammonium, mono-, di- and triethanolammonium and alkali metal salts; from 1% to 4% of a water-soluble alkyleneoxylated nonionic detergent selected from the group consisting of condensates of C 8 -C 18 alkanol with 2-15 moles of ethylene oxide, condensates of C 6 -C 12 alkylphenol with 5 to 30 moles of ethylene oxide and condensates of C 10 -C 16 alkanol with a heteric mixture of ethylene oxide and propylene oxide in a weight ratio of 2.5:1 to 4:1 with the total alkylene oxide content being 60% to 85% by weight, the weight ratio of anionic detergent to nonionic detergent being from 0.5:1 to 6:1; 2% to 15% of a water-soluble detergent builder salt, the weight ratio of builder salt to total detergent being in the range of 1:5 to 5:1; 0-2% of C 8 -C 18 fatty acid, 0-8% of urea; and the balance water.
Claim 2
Dependent Claim 195 words
A self-opacified, impalpable, homogeneous, liquid, hard surface cleaner consisting essentially of, by weight, from 2% to 6% of a water-soluble, synthetic, anionic, sulfated or sulfonated detergent salt containing an alkyl radical of 8 to 22 carbon atoms in the molecule, said salt being selected from the group consisting of ammonium, mono-, di- and triethanolammonium and alkali metal salts; from 1% to 4% of a water-soluble alkyleneoxylated nonionic detergent selected from the group consisting of condensates of C 8 -C 18 alkanol with 2-15 moles of ethylene oxide, condensates of C 6 -C 12 alkylphenol with 5 to 30 moles of ethylene oxide and condensates of C 10 -C 16 alkanol with a heteric mixture of ethylene oxide and propylene oxide in a weight ratio of 2.5:1 to 4:1 with the total alkylene oxide content being 60% to 85% by weight, the weight ratio of anionic detergent to nonionic detergent being from 0.5:1 to 6:1; 2% to 15% of a water-soluble detergent builder salt, the weight ratio of builder salt to total detergent being in the range of 1:5 to 5:1; 0-2% of C 8 -C 18 fatty acid, 0-8% of urea; and the balance water.
Claim 3
Dependent Claim 17 words

Claim 6
Dependent Claim 23 words
A cleaner as claimed in claim 1 wherein said fatty acid is present and is a C 8 -C 18 saturated fatty acid.
Claim 7
Dependent Claim 26 words
A cleaner as claimed in claim 1 wherein the builder is a 10:1 to 1:10 mixture by weight, of two different non-phosphate alkali metal builder salts.
Claim 8
Dependent Claim 26 words
A cleaner as claimed in claim 1 wherein the ratio by weight of anionic detergent to nonionic detergent is in the range from 3:2 to 4:2.
Claim 9
Dependent Claim 25 words
A cleaner as claimed in claim 1 wherein the ratio by weight of builder to total detergents is in the range from 1:2 to 2:1.
Claim 10
Dependent Claim 29 words
A cleaner as claimed in claim 1 wherein said urea is present and the weight ratio of urea to the sum of detergents and builder is up to 8:5.
Claim 11
Dependent Claim 71 words
