Use of a mixture comprising a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground deposits of hydrocarbons for mobilizing and recovering the hydrocarbons from the underground deposits, the cosurfactant being a substance or a group of substances selected from the following list: 

Surfactant mixtures for tertiary oil recovery

The invention relates to a mixture comprising a surfactant and a cosurfactant, the cosurfactant being an amphiphilic polymer having one or more hydrophobic subunits (A) and one or more hydrophilic subunits (B), wherein one or more hydrophobic subunits (A) have been formed on the basis of a polyisobutene block whose polyisobutene macromolecules have terminal double bonds to an extent of at least 50 mol %.

Mixture comprising a detergent and a co-detergent

A mixture of surfactant and co-surfactant which is an amphiphilic polymer with the formula: 

Mixture, comprising a surfactant and a cosurfactant that is an amphiphilic polymer

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.
