Cosmetic, pharmaceutical or dermatological formulation, containing one or more homo- and / or copolymer waxes based on the ethylene and / or propylene monomers, characterized in that the homo- and copolymer waxes have a weight average molecular weight Mw less than or equal to 25,000 g / mol, a number average molecular weight Mn less than or equal to 15,000 g / mol, a distribution of the molecular masses Mw / Mn in the range of 1.5 to 10, preferably 1.5 to 5, especially preferably 1.5 to 3, and particularly preferably 2 to 2.5, and have been obtained by catalysis with a metallocene, and containing the copolymer waxes, based on the total weight of the waxes of copolymers, from 0.1 to 30.0% by weight of structural units that come from one of the monomers and from 70.0 to 99.9% by weight of some structural units that come from the other monomer. |
