The ester sulfonate-containing surfactant concentrates contain (a) one or more surfactants in an amount of 50 to 70% by weight, based on the total weight of the concentrates, from the groups alkali salts of α-sulfonated fatty acid alkyl esters as anionic surfactants and linear aliphatic fatty alcohol polyglycol ethers as nonionic surfactants a ratio of anionic surfactant: nonionic surfactant in the range from 1: 0.3 to 1: 3, (b) one or more saturated and / or unsaturated linear aliphatic carboxylic acids in amounts of 10 to 30% by weight, based on the total weight of the concentrates , and (c) water in amounts of 0 to 10 wt .-%, based on the total weight of the concentrates. The invention also relates to the use of such concentrates in detergents, dishwashing detergents and cleaning agents for household and industrial purposes. |
