Abstract: A method of preparing an ester by reacting a carboxylic acid with a (C1-C36)alcohol in the presence of a catalyst that is suitable for preparing carboxylic acid esters of monomeric carboxylic acids in high yield. The method reduces by-products of the reaction, in particular esters of dimeric, trimeric and/or oligomeric carboxylic acids. The method requires a minimal excess of alcohol and does not require removal of water and/or carboxylic acid ester from the reaction mixture. The method is particularly suitable for the reaction of hydroxyalkylcarboxylic acids and fatty alcohols.

Abstract: Mixtures of Guerbet alcohols, their use in cosmetic and/or pharmaceutical preparations, and also cosmetic and/or pharmaceutical preparations comprising mixtures of Guerbet alcohols are described. Of suitability as petroleum jelly substitute are in particular Guerbet alcohol mixtures with a melting range, measured by differential scanning 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. These 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 from 8 to 22 carbon atoms and c) optionally an aliphatic diol having at least 3 carbon atoms.

Abstract: Described herein are mixed ethers and cosmetic and/or pharmaceutical preparations comprising mixed ethers. Certain mixed ethers have a melting range between −25° C. and +70° C., wherein the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35 ±10° C. These mixed ethers are obtainable for example by condensation reaction of a) 25 to 90% by weight of unbranched fatty alcohols with a chain length of 12 to 19 carbon atoms; b) 5 to 50 by weight of isostearyl alcohol; c) 0 to 35% by weight of a fatty alcohol with a chain length of 20 and/or 22 carbon atoms; and d) 0 to 25% by weight of a fatty alcohol having 8 and/or 10 carbon atoms.
