Ester-sulfonate-containing liquid surfactant concentrates containing one or more surfactants in a quantity of 50 to 70% by weight, based on the total weight of the concentrates, selected from the group consisting of alkali metal of .alpha.-sulfonated fatty acid alkyl esters such as anionic surfactants and linear aliphatic fatty alcohol polyglycol ethers as nonionic surfactants in a ratio of anionic surfactant to nonionic surfactant of from 1:0.3 to 1:3, one or more saturated and/or unsaturated linear aliphatic carboxylic acids in a quantity of from 10 to 30% by weight, based on the total weight of the concentrates, and water in a quantity of from 0 to 10% by weight, based on the total weight of the concentrates. The invention also relates to the use of these concentrates in fabric detergents, dishwashing detergents and cleaning preparations for domestic and industrial purposes.
