2095431 9208690 PCTABS00013 Ethanolamide ethoxylate of the general formula RICONHC2H4O(A)xH wherein RI is a hydrocarbon group having 1-29 carbon atoms, A is an alkyleneoxy group derived from an alkylene oxide having 2-4 carbon atoms, and x is 2-30, is produced by reacting a compound of the general formula RICONHC2H4OH wherein RI and n have the meanings stated above, with an alkylene oxide having 2-4 carbon atoms in the presence of a tertiary amine lacking protons that react with alkylene oxide, or an alkylene-oxide-quaternised derivative thereof at a temperature ranging from room temperature to 120 ·C. This gives high yields of the ethoxylate, which has low contents of undesired secondary compounds. The ethoxylate is conveniently used in detergent compositions.
