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.

Abstract: The invention pertains to a new route to prepare ?-functionalized carboxylic acid esters in a one-pot reaction, by reacting an olefinic acid ester in the presence of a catalyst system, comprising a Rh(I)-complex, together with an aryl boron or a diamine as nucleophilic compounds, and under oxygen-free conditions and elevated temperatures.

Abstract: A composition for cosmetic compositions which contains (a) at least one dicarboxylic acid diester of a C6-C13 dicarboxylic acid with a C12-22 fatty alcohol; (b) at least one oil component. The composition provides excellent antiperspirant and deodorant sticks when combined with an antiperspirant or deodorizing composition. Addition of a pigment provides cosmetic sticks such as lipsticks. The composition can be water free.

Abstract: A process for the production of hydrocarbons by dehydrating primary alcohols with a dehydration catalyst of trifluoromethansulfonic acid is disclosed.
