1. 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 C2 -C3 alkoxylated C10 -C18 alkanol nonionic detergent;
4% to to 12% of a C2 -C3 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.

9. A method of controlling the viscosity of a liquid detergent consisting essentially of, by weight, 10% to 60% of a water-soluble C2 -C3 alkoxylated C10 -C18 alkanol nonionic detergent, 4% to 12% of C2 -C3 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.
- 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°
