  • Publication number: 20010044550
    Abstract: A process for the branching of saturated and/or unsaturated fatty acids and/or alkyl esters thereof comprises subjecting the fatty acids and/or alkyl esters to a skeletal isomerization reaction using a catalyst comprising a crystalline porous structure having incorporated therein a metal to form metal sites on said catalyst and isolating branched fatty acids, alkyl esters thereof, or mixtures thereof, from a reaction mixture obtained by said skeletal isomerization reaction. The catalyst used in the isomerization reaction is preferably a zeolite catalyst containing metal sites of a Group VIII metal. The process produces a mixture of fatty acids and/or alkyl esters that contain significant quantities of branched molecules.

  • Patent number: 6281181
    Abstract: Light-duty liquid or gel dishwashing detergent compositions that are especially useful for manual washing of heavily soiled dishware under conditions of low temperature and high hardness. Such compositions contain a surfactant system comprising a mid-hain branched surfactant. Preferably, the compositions also comprise a polyhydroxy fatty acid amide-based nonionic surfactant component, a detersive amount of magnesium or calcium, a suds booster which is preferably an amine oxide and an aqueous liquid carrier. The detergent compositions exhibit excellent phase stability at low temperatures and excellent mixing rates with water, even at low temperature and/or high water hardness.
