The invention relates to a hydrocarbon mixture that contains at least two hydrocarbons that are different from each other, the number of carbons thereof differing by more than one, wherein said two hydrocarbons that differ from each other make up at least 60% by weight, preferably at least 70% by weight of the total of the hydrocarbons. The invention also relates to the use of said hydrocarbon mixtures and to cosmetic and/or pharmaceutical preparations containing said hydrocarbon mixtures.

Hydrocarbon mixtures and use thereof

The invention relates to esters of general formula (I) R&#x2014;C(&#x2550;O)&#x2014;O&#x2014;R, wherein (1) Rrepresents a linear alkyl radical having 7 to 9 carbon atoms and Rrepresents a linear alkyl radical having 9 to 10 carbon atoms or (2) Ris a linear alk radical having 8 to 9 carbon atoms and Ris a linear alkyl radical having 8 carbon atoms, or (3) Ris a linear alkyl radical having 7 to 9 carbon atoms and Ris a linear alkyl radical having 7 carbon atoms, or (4) Ris an alkyl radical having 7 or 8 carbon atoms and Ris an alkyl radical having 9 carbon atoms where, if Ris a linear alkyl radical, Ris a branched alkyl radical, or, if Ris a branched alkyl radical, Ris a linear alkyl radical or (5) Rrepresents an alkyl radical having 8 carbon atoms and Ris an alkyl radical having 8 carbon atoms, where, if Ris a linear alkyl radical, Ris a branched alkyl radical, or, if Ris a branched alkyl radical, Ris a linear alkyl radical, or n-octyl isooctanoate, n-decyl isooctanoate, n-decyl isononanoate, isononyl n-decanoate, n-heptyl n-dodecanoate or isononyl isooctanoate.

Linear alkyl esters and their use in cosmetic and/or pharmaceutical compositions
