Abstract:
A process for the production of branched, substantially unsaturated fatty alcohol ether sulfates comprising the steps of: (a) dimerizing an unsaturated C16-22 fatty acid to form a dimer fraction and a monomer fraction comprised of branched, substantially unsaturated fatty acids and straight chain saturated fatty acids, (b) separating the monomer fraction from the dimer fraction, (c) converting the branched, substantially unsaturated fatty acids in the monomer fraction into the corresponding fatty acid methyl esters, (d) hydrogenating the branched, substantially unsaturated fatty acid methyl esters with the double bonds intact to form the corresponding branched, substantially unsaturated fatty alcohols and (e) sulfating and neutralizing the branched, substantially unsaturated fatty alcohols.
