Composition containing a) at least one N-methyl-N-acylglucamine of the formula (I) wherein R 1 is a linear or branched, saturated or unsaturated hydrocarbon chain having 7 to 21 carbon atoms, b) one or more organic acids of the formula (II), or salts thereof, R 2 -COOM (II) in which R 2 is a linear or branched alkyl group or a linear or branched, mono- or polyunsaturated alkenyl group having 5 to 29 carbon atoms, and M are hydrogen or one or more cations, wherein the cations are present in charge-balancing quantities. and c) one or more alkanolamines of the formula (III) NR 1 R 2 R 3 (III) in which R 1 , R 2 and R 3 are hydrogen, a linear or branched alkyl group having 1 to 4 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms, a linear or branched hydroxyalkyl group having 2 to 5 carbon atoms and 1 or 2 hydroxy groups or a hydroxy ether group with 2 to 6 carbon atoms, with the proviso that at least one of the radicals is a hydroxyalkyl group or a hydroxy ether group. |
