USE OF N-POLYHYDROXYALKYL FATTY ACID AMIDES AS THICKENER FOR AQUEOUS SURFACE ACTIVING LIQUID SYSTEM

摘要

1. The use of N-polyhydroxyalkyl fatty acid amides of the general formula see diagramm : EP0285768,P6,F2 in which, R1 represents a branched or unbranched alkyl radical having 1 to 17 carbon atoms, R2 represents hydrogen, a branched or unbranched alkyl radical having 1 to 18 carbon atoms or a radical see diagramm : EP0285768,P6,F3 where n=0 or 1 to 5 and R3 may be hydrogen or -CH3 and X represents a polyhydroxyalkyl radical having 4 to 7 carbon atoms which, if desired, is linked glycosidically with a mono-, di- or oligo-saccharide radical, as thickening agents for liquid aqueous surfactant systems.
