Abstract: A process for the production of hydrocarbons by dehydrating primary alcohols with a dehydration catalyst of trifluoromethansulfonic acid is disclosed. The hydrocarbons so produced have fewer undesired secondary reactions. Accordingly, cosmetic and cleaning compositions incorporating the hydrocarbons produced by way of the process are also disclosed.

Abstract: A process is provided for the production of linear saturated alkanes from one or more primary alcohols, wherein the carbon chain of the one or more primary alcohols has one carbon atom more than the alkane, including conducting reductive dehydroxymethylation of one or more primary fatty alcohols containing 8 to 24 carbon atoms, at a temperature ranging from 100 to 300° C. and pressures from 1 to 250 bar in the presence of hydrogen and a catalyst, and removing water formed during the reaction.

Abstract: A cosmetic or pharmaceutical composition is provided. The composition contains a mixture of oils prepared by Kolbe electrolysis of branched chain fatty acids and mixtures of branched chain fatty acids with straight chain fatty acids. The fatty acids containing from 3 to 26 carbon atoms. The oils are a mixture of oils with different spreading rates (spreading cascade).

Abstract: Process for producing poly-?-olefins are described wherein the processes comprise: (a) providing a primary alcohol; and (b) polymerizing the primary alcohol in the presence of an acidic alumino layer silicate to form a poly-?-olefin. Water formed during the polymerization can be removed, optionally during the polymerization, and subsequent hydrogenation may be performed.

Abstract: The disclosed invention relates to a cosmetic composition containing at least one branched oligo-?-olefin, characterized in that the side chains at one branch point at least are ethyl, propyl or longer branched alkyl chains, the branched oligo-?-olefin being obtainable by oligomerization of a) at least one branched ?-olefin containing 5 to 18 carbon atoms, b) at least one linear ?-olefin containing 4 to 10 carbon atoms, c) a mixture of a branched ?-olefin containing 4 to 18 carbon atoms and a linear ?-olefin containing 3 to 18 carbon atoms or d) a mixture of various branched ?-olefins containing 4 to 18 carbon atoms and linear ?-olefins containing 3 to 18 carbon atoms in the presence of a catalyst selected from the group consisting of organic acids, cationic ion exchangers, silica gels, layer silicates, inorganic acids or Lewis-acid-based catalysts.

Abstract: The invention is directed to a cosmetic composition which contains at least one poly-?-olefin produced by subjecting at least one primary alcohol to dehydrating polymerization at a temperature of 60° C. to 340° C. in the presence of acidic alumino layer silicates. The primary alcohol is an alcohol from the group of unsaturated monofunctional alcohols, branched monofunctional alcohols and difunctional alcohols. The poly-?-olefin is a high-spreading oil component which imparts an almost instantaneous and relatively long-lasting feeling of smoothness to the skin and has good dermatological compatibility.
