A mixture comprising a component I comprising 80-20% by weight of a first surfactant component I1, which is an alkylpolyglucoside containing 1-2 glucoside moieties and a hydrocarbon moiety, especially an alkyl residue of 6-16 carbon atoms, 20-80% by weight of a component I2, which is a second surfactant containing alcohol groups other than an alkylpolyglucoside, the weight proportions being based on component I only; and a polymeric additive as component II, wherein the polymeric additive, as component III, contains at least one water-soluble moiety and at least one hydrophobic moiety, the ratio of the number average molecular weights of all water-soluble moieties to the number average molecular weights of all hydrophobic moieties being from 2:1 to 1000:1 or from 3.1 to 1000:1, especially from 5:1 to 200:1, in particular from 10:1 to 50:1, wherein each of said at least one hydrophobic moieties has a number average molecular weight of at most 1000 g/mol; or the polymeric additive, as component II2, contains at least one water-soluble moiety and at least one hydrophobic moiety and is an amphiphilic comb polymer including a backbone with two or more side chains attached to said backbone, wherein the side chains are distinguished from one another and/or from the backbone in terms of their amphiphilic character; or the polymeric additive, as component II3, contains at least one water-soluble moiety and at least one hydrophobic moiety wherein said polymeric additive as component II3 is an AB diblock copolymer or an ABA or BAB triblock copolymer with water-soluble A blocks and hydrophobic B blocks. |
