Abstract: The invention comprises dermatological or cosmetic preparations comprising a triple combination of anionic polymer and two rheology modifying polymers which increase the viscosity of the preparation by at least 200% at a high shear rate and do not increase the viscosity at a low shear rate by more than 50%, thus imparting an improved sensory richness during spreading, in comparison to preparations without this combination.

Abstract: The invention relates to the use of nitrogenous aluminium organyl complexes of general formula (I) as co-catalysts in heterogeneous polymerisation reactions of propene. In said formula: R, R?, R1 and R1? independently of one another represent branched or unbranched C1-C7 alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl or alkynyl; R2 represents unsubstituted, monoalkylated or polyalkylated and/or monofluorinated or polyfluorinated aromatic hydrocarbons from group (II); R3 and R4 independently of one another represent CH2, CF2 oder C(R1)2; m stands for 0, 1 or 2; n stands for 0, 1 or 2; o stands for 0 or 1, all independently of one another.
