Abstract
Abstract A liquid detergent having a viscosity in the range of 40 to 100 centipoises at 24° C and which is fluid at 7° C which consists essentially of, by weight, from 10% to 60% of a water soluble C 2 -C 3 alkoxylated C 10 -C 18 alkanol nonionic detergent, 4 to 12% of C 2 -C 3 alkanol, 1 to 6% of a water soluble salt of a dibasic acid of the formula (CH 2 ) n (COOH) 2 , wherein n is 3 to 5 as a viscosity control and gel prevention agent, and the balance water.

Claim 2
Dependent Claim
98 words
A liquid detergent having a viscosity in the range of 40 to 100 centipoises at 24° C. and which is fluid at 7° C. which consists essentially of, by weight, from 10 to 60% of a water-soluble C 2 -C 3 alkoxylated C 10 -C 18 alkanol nonionic detergent, 4 to 12% of a C 2 -C 3 alkanol, 1 to 6% of water-soluble salts of dibasic acids of the formula (CH 2 ) n (COOH) 2 , wherein n is 3 to 5 as a viscosity control and gel prevention agent, and 22 to 84.5% of water.
Claim 3
Dependent Claim
100 words
A liquid detergent according to claim 1 in which the nonionic detergent is a polyethoxylated alkanol, said lower alkanol is selected from the group consisting of ethanol, isopropanol and mixtures thereof, and which contains from 20 to 40% of the polyethoxylated alkanol and 4 to 12% of a water-soluble synthetic organic anionic detergent salt having a carboxylate, sulfate or sulfonate group in its molecular structure and selected from the group consisting of sodium, potassium, ammonium and triethanolamine salts, 6 to 10% lower alkanol or mixture thereof, 1.5 to 5% of said dibasic acid salt and 29 to 69.5% of water.
Claim 4
Dependent Claim
69 words
A liquid detergent according to claim 2 wherein the nonionic detergent is a polyethoxylated C 10 -C 18 alkanol having from 3 to 12 ethylene oxide groups per mol and the anionic detergent is selected from the group consisting of water-soluble salts of polyethoxylated C 10 -C 18 alkanol ether sulfates having from 2 to 8 ethylene oxide groups per mol and C 10 -C 15 alkyl benzene sulfonates.
Claim 5
Dependent Claim
54 words
A liquid detergent according to claim 1 wherein the nonionic detergent is a polyethoxylated higher alkanol wherein the higher alkanol is of 11 to 15 carbon atoms and which contains from 5 to 9 ethoxy groups per mol, the anionic detergent is a sodium salt, and said dibasic acid salt is a sodium salt.
Claim 6
Dependent Claim
89 words
A liquid detergent according to claim 4, which consists essentially of 30 to 40% of said polyethoxylated alkanol, 4 to 12% of the anionic detergent, which is a sodium polyethoxy linear higher alkanol sulfate wherein the alkanol is of 12 to 15 carbon atoms and which contains from 2 to 5 ethylene oxide groups per mol, 1.5 to 5% of sodium adipate, 6 to 8% of ethanol or a mixture of ethanol and isopropanol in which ethanol is present in a major proportion, and 34 to 57.5% of water.
