  • Preparation of alkylpolyglycosides and cleaning compositions comprising same
    Patent number: 5962399
    Abstract: A process for preparing high detergency or surfactant alkyl polyglycoside compositions and a purified alkyl monoglycoside and to compositions employing the polyglycosides for various end use applications. The process involves removal of a substantial portion of the monoglycoside present in a reaction product mixture containing alkyl polyglycosides resulting from the reaction of an alcohol and saccharide at elevated temperatures in the presence of an acid catalyst. Separation of the monoglycoside from the reaction product mixture may be carried out by molecular distillation.
    Type: Grant
