    Abstract: Mixtures of Guerbet alcohols, their use in cosmetic and/or pharmaceutical preparations, as well as cosmetic and/or pharmaceutical preparations comprising mixtures of Guerbet alcohols are described. Particularly Guerbet alcohol mixtures with a melting range, measured by dynamic differential calorimetry (DSC), between -20°C and +70°C, where the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35 ± 10°C, are suitable as Vaseline substitute. Said mixtures are obtainable for example by reacting a) 55 to 95% by weight of cetylstearyl alcohol, b) 5 to 45% by weight of fatty alcohols with a chain length of 8 to 22 carbon atoms and c) optionally an aliphatic diol with at least 3 carbon atoms.

    Abstract: The present invention relates to a method for producing compositions containing unsaturated compounds, wherein (A) one or a plurality of unsaturated monocarboxylic acids with 10 to 24 C atoms or esters of these monocarboxylic acids and (B) one or a plurality of unsaturated dicarboxylic acids with 4 to 20 C atoms or esters thereof are subjected to a tandem isomerization/metathesis reaction in the presence of a palladium catalyst and a ruthenium catalyst, with the condition that compounds which contain at least one Pd-P(R
    1 R
    2 R
    3 ) structure element are used as the palladium catalysts, wherein the R
    1 to R
    3 radicals each - independently of one another - have 2 to 10 C atoms, which can each be aliphatic, alicyclic, aromatic, or heterocyclic, with the condition that at least one of the R
    1 to R
    3 radicals contains a beta hydrogen, wherein the palladium catalyst is used as such or generated in situ, with the condition that the method is performed in the absence of substances having a pKa value of 3 or less.
