Fatty acid polyoxyalkyl ester sulfonates, obtainable by reacting Cāā-Cāā monounsaturated monocarboxylic acid polyoxyalkyl esters of the general formula I. C m H 2m-1 -CO- (OC n H 2n ) x -OR (I) in the R is an alkyl radical with 1-22 carbon atoms or an alkenyl radical with 3-22 carbon atoms, m the numbers 10, 15, 17, 19 or 21, n the numbers 2 and / or 3 and x is a number from 1 to 20, with sulfur trioxide and subsequent reaction of the sulfonated fatty acid polyoxyalkyl ester obtained with aqueous alkalis have a high surface activity and good surfactant properties. |
