<p>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.</p> |
