There are described cosmetic, pharmaceutical or dermatological preparations containing one or more homo- and / or copolymer waxes of the monomers ethylene and / or propylene. The homo- and copolymer waxes have a weight-average molecular weight Mw of less than or equal to 25,000 g / mol, a number-average molecular weight Mn of less than or equal to 15,000 g / mol, a molecular weight distribution Mw / Mn in the range of from 1.5 to 10, and were obtained by metallocene catalysis , The copolymer waxes contained, based on the total weight of the copolymer waxes, 0.1 to 30.0 wt .-% of structural units resulting from the one monomer and 70.0 to 99.9 wt .-% of structural units resulting from the other monomer. |
