Abstract
Abstract A liquid detergent having a viscosity in the range of 40 to 120 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, the proportion of alcohol being such that the physical properties of the liquid detergent would be unsatisfactory in the absence of a viscosity control and gel prevention agent 1% to 6% of sodium or potassium formate as a viscosity control and gel prevention agent and 22 to 84.5% of water.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A liquid detergent having a viscosity in the range of 40 to 120 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 to 12% of a C 2 -C 3 alkanol, the proportion of alcohol being such that the physical properties of the liquid detergent would be unsatisfactory in the absence of a viscosity control and gel prevention agent; 1% to 6% of sodium or potassium formate as a viscosity control and gel prevention agent and 22 to 84.5% of water.
Claim 2
Dependent Claim
110 words
A liquid detergent having a viscosity in the range of 40 to 120 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 to 12% of a C 2 -C 3 alkanol, the proportion of alcohol being such that the physical properties of the liquid detergent would be unsatisfactory in the absence of a viscosity control and gel prevention agent; 1% to 6% of sodium or potassium formate as a viscosity control and gel prevention agent and 22 to 84.5% of water.
Claim 3
Dependent Claim
92 words
A liquid detergent according to claim 1 in which the nonionic detergent is a polyethoxylated alkanol which is present in an amount of 20% to 40% by weight, said lower alkanol is selected from the group consisting of ethanol, isopropanol and mixtures thereof, and which contains, in addition, 4 to 12% by weight of a water-soluble synthetic organic anionic detergent salt having carboxylate, sulfate or sulfonate group in its molecular structure and selected from the group consisting of sodium, potassium, ammonium and triethanolamine salts, and 29 to 69.5% by weight 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 polyethoxy 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
32 words
A liquid detergent according to claim 3 wherein said alkanol is ethanol which is present in an amount of 4% to 8% by weight and said viscosity control agent is sodium formate.
Claim 6
Dependent Claim
36 words
A liquid detergent according to claim 3 wherein the nonionic detergent is a polyethoxylated C 11 -C 15 alkanol having from 5 to 9 ethoxy groups per mol and the anionic detergent is a sodium salt.
Claim 7
Dependent Claim
59 words
A liquid detergent according to claim 4 wherein said nonionic detergent is present in an amount of 30% to 40% by weight and said anionic detergent is a sodium polyethoxy linear C 12 -C 15 alkanol sulfate having from 2 to 5 ethylene oxide groups per mol which is present in an amount of 4% to 12% by weight.
Claim 8
Dependent Claim
47 words
A liquid detergent according to claim 4 wherein said nonionic detergent is present in an amount of 30% to 40% by weight and said anionic detergent is a sodium C 10 -C 14 alkylbenzene sulfonate which is present in an amount of 4% to 12% by weight.
Claim 9
Dependent Claim
38 words
A method of washing laundry which consists essentially of washing laundry in water containing 0.05% to 0.03% by weight of the liquid detergent of claim 1, said water being at a temperature of 10° C. to 80° C.
Claim 10
Independent Claim
121 words
A method of controlling the viscosity of a liquid detergent consisting essentially of, by weight, 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, the proportion of said alcohol being insufficient to obtain the desired viscosity range and to maintain fluidity at 7° C., and water which comprises incorporating from 1% to 6% by weight of a water-soluble sodium or potassium formate in said liquid detergent, the mixture of said alcohol and said formate being effective to provide a composition which is fluid at 7° C. and which has a reduced viscosity as compared with the same composition not containing the formate salt.
Claim 11
Independent Claim
121 words
A method of controlling the viscosity of a liquid detergent consisting essentially of, by weight, 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, the proportion of said alcohol being insufficient to obtain the desired viscosity range and to maintain fluidity at 7° C., and water which comprises incorporating from 1% to 6% by weight of a water-soluble sodium or potassium formate in said liquid detergent, the mixture of said alcohol and said formate being effective to provide a composition which is fluid at 7° C. and which has a reduced viscosity as compared with the same composition not containing the formate salt.
