The present invention relates to a process for preparing esters from fatty alcohols, in which fatty alcohols and fatty acids are reacted in the presence of an enzyme at a temperature in the range of 30 to 50&#xb0; C., the water which forms is removed and the reaction is completed under reduced pressure at a temperature of 50 to 80&#xb0; C.

Ester synthesis

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 &#x2212;20&#xb0; C. and +70&#xb0; C., where the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35&#xb1;10&#xb0; C. These are obtainable for example by reacting

Guerbet alcohol mixtures and uses thereof

The disclosed invention refers to a process for obtaining fatty acid alkyl esters, rosin acids and sterols from crude tall oil (CTO), which is characterized by the following steps: (a) reacting the free fatty acids present in the CTO with lower alcohols; (b) esterifying the sterols in the CTO with boric acid or transesterifying the sterols with a catalyst; (c) separating the fatty acid lower alkyl esters and rosin acids from the remaining sterol borate esters or sterol esters of fatty acids to produce a stream of sterol esters; (d) separating the fatty acid alkyl esters from the rosin acids to produce a first stream of fatty acid alky esters and a second stream of rosin acids; and (e) converting the sterol esters into the free sterols to produce a third stream of free sterols.

Process for obtaining fatty acid alkyl esters, rosin acids and sterols from crude tall oil

Described herein are mixed ethers and cosmetic and/or pharmaceutical preparations comprising mixed ethers. Certain mixed ethers have a melting range between &#x2212;25&#xb0; C. and +70&#xb0; C., wherein the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35 &#xb1;10&#xb0; 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.

Mixed ethers and uses thereof

Described are alkoxylated glycerol acetals according to Formulas (Ia) and (Ib) wherein Rrepresents a linear or branched, saturated or unsaturated and optionally substituted hydrocarbyl residue comprising 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, a benzyl or furfuryl radical, Ris selected from hydrogen, an alkyl, alkenyl or hydroxyalkyl group having 6 to 22 carbon atoms or an acyl group having 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, AO represents an ethylene oxide, a propylene oxide, a butylene oxide unit, or their mixtures, and n is an integer of about 1 to about 100.

Alkoxylated glycerol acetals and their derivatives

The invention relates to a process for production of fatty acids directly from soapstock generated in the alkali refining process including the steps of (a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of glycerides without prior neutralization, (b) neutralizing and splitting the soaps with strong acids, and (c) separating the fatty acid phase from the aqueous phase by settling and/or centrifugation. A second embodiment is a process in which the soapstock is first neutralized and split with strong acids, followed by adding a lipase to facilitate glyceride hydrolysis, and separating the fatty acid phase. The fatty acids so obtained can be esterified with C1-C6 alcohols using a lipase that is selective for fatty acids and does not transesterify the sterolesters, and the fatty acid esters and sterolesters are separated by distillation. The sterolesters are useful as supplements for food, as pharmaceutical agents for lowering cholesterol and as biofuel and biodiesel.

Process for production of fatty acids, fatty acid esters and sterolesters from soapstock

A process for enriching and separating polyunsaturated fatty acid (PUFA) acyl groups in a fatty acid mixture, which mixture contains other non-PUFA fatty acid acyl groups, is disclosed.
