The invention relates to the use of cross-linked polymers that can be obtained by the polymerisation of a mixture containing between 99.99 and 10 wt. % of at least one a,?-ethylenically unsaturated compound containing at least one cationogen and/or cationic group per molecule, between 0 and 90 wt. % of at least one of a) different monoethylenically unsaturated compounds containing amide groups, and between 0.01 and 5 wt. % of a cross-linking agent for modifying the rheology of aqueous, alcoholic or aqueous/alcoholic compositions. The invention also relates to cosmetic or pharmaceutical preparations based on water or alcohol, especially in the form of gels, containing said cross-linked polymers. |
