Patent number: 9333262Abstract: 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.Type: GrantFiled: February 15, 2013Date of Patent: May 10, 2016Assignee: BASF SEInventors: Peter Kempers, Rolf Kawa, Stefan Brüning, Jadranka Milardovic, Eike Ulf Mahnke, Heinz-Josef Krüppel, Markus Dierker, Burkhard Beckedahl

Patent number: 8993811Abstract: 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.Type: GrantFiled: February 15, 2013Date of Patent: March 31, 2015Assignee: BASF SEInventors: Markus Dierker, Peter Kempers, Rolf Kawa, Stefan Brüning, Jadranka Milardovic, Burkhard Beckedahl, Eike Ulf Mahnke, Heinz-Josef Krüppel

Patent number: 5612467Abstract: Light-colored alkyl oligoglycoside pastes can be obtained by a process in whicha) glycose is reacted with fatty alcohols in the presence of acidic catalysts at elevated temperature to a residual content of glycose of less than 0.1% by weight, based on the starting quantity of glycose,b) water of reaction released is continuously removed from the equilibrium,c) the reaction products are neutralized with a base, the molar ratio of hydrogen ions in the reaction mixture to added base being from 1:1 to 1:1.5,d) unreacted fatty alcohols is separated by distillation,e) the residue is subsequently processed by addition of water to a paste having a solids content of 30 to 70% by weight, based on the paste, the paste is alkalized and, optionally, bleached by methods known per se.Type: GrantFiled: April 21, 1994Date of Patent: March 18, 1997Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Manfred Weuthen, Burkhard Beckedahl, Irmgard Hartel
