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.
