Abstract

A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
