Estimating the term…
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.
A hard surface cleaner containing
A soil cleaning composition containing
A laundry detergent containing an alkylpolyglycoside surfactant composition having an HLB in the range of about 10 to about 16, in which the alkyl group contains from about 6 to about 20 carbon atoms, said alkyl polyglycoside surfactant composition comprising a mixture of:
A method of preparing a cleaning composition comprising adding to said cleaning composition a surfactant effective amount of an alkylpolyglycoside surfactant having an HLB in the range of about 10 to about 16, in which the alkyl group contains from about 6 to about 20 carbon atoms, said alkyl polyglycoside surfactant composition comprising a mixture of:
An alkyl polyglycoside composition having an HLB in the range of about 10 to about 16, in which the alkyl group contains from about 6 to about 20 carbon atoms, said alkyl polyglycoside surfactant composition comprising a mixture of:
A method of preparing an improved alkylpolyglycoside surfactant composition in which the alkyl groups contain from about 6 to about 20 carbon atoms comprising selecting a predetermined average carbon chain length of the alkyl moiety for the composition and mixing two or more of at least binary components of alkylpolyglycosides, each binary component having an average alkyl chain length such that when mixed, the amounts of the binary components mixed are effective to provide the predetermined selected average alkyl moiety and the surfactant properties and wherein at least one, or both binary components, comprise a non-Flory distribution of polyglycosides derived from an acid-catalyzed reaction of an alcohol containing 6-20 carbon atoms and a suitable saccharide from which excess alcohol has been separated.
