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 a water-free oil-based composition which is liquid at 20&#xb0; C./normal pressure and which contains

Emollient mixture for cosmetic and pharmaceutical formulations

The invention relates to hydrocarbon mixtures containing theC isotope, use thereof and cosmetic and/or pharmaceutical preparations comprising hydrocarbon mixtures containing theC isotope.

A smooth, dry-feeling, less-greasy, substantially-odorless, ecotoxicologically-safe, wax-based composition with a melting point above 25&#xb0; C., comprising one or more wax components selected from dialkyl carbonates, dialkylene carbonates, and mixtures of two or more thereof; less than 10%, by weight, of water; and (c) optionally, one or more components selected from the group consisting of one or more wax or oil components selected from the group consisting of dialkyl ethers, dialkylene ethers, dicarboxylic acids, hydroxyfatty alcohols, and mixtures of two or more thereof, as well as one or more wax-like lipid components, other than those in previously listed, one or more other oil components, liquid at 20&#xb0; C. and immiscible with water at 25&#xb0; C., other than those previously listed, one or more emulsifiers, one or more zwitterionic, amphoteric, cationic or anionic surfactants, one or more other auxiliaries and/or additives, and one or more physiologically-active components, which compositions are useful in a cosmetic, personal hygiene and/or body-care preparation.

Smooth-feeling wax-based compositions for personal care preparations

The invention relates to hydrocarbon mixtures containing linear C11 and linear C13 hydrocarbons, wherein the sum of the linear C11 and linear C13 hydrocarbons is greater than or equal to 60 wt. % with relation to the sum of the hydrocarbons, and to the use of said mixtures in cosmetic and/or pharmaceutical preparations.
