Amphiphilic water-soluble alkoxylated polyalkylenimines of the general formula I in which the variables are each defined as follows: R are identical or different, linear or branched C2-C6-alkylene radicals; B is a branch; E is an alkylenoxy unit of the formula R1 is 1,2-propylene, 1,2-butylene and/or 1,2-isobutylene; R2 is ethylene; R3 is 1,2-propylene; R4 are identical or different radicals: hydrogen; C1-C4-alkyl; x, y, z are each from 2 to 150, where the sum of x+y+z means a number of alkylenimine units which corresponds to an average molecular weight Mw of the polyalkylenimine before the alkoxylation of from 300 to 10 000; m is a rational number from 0 to 2; n is a rational number from 6 to 18; p is a rational number from 3 to 12, where 0.8≦̸n/p≦̸1.0(x+y+z)1/2; and quaternization products thereof.
