Abstract
The invention relates to new anionic detergent mixtures obtained by reacting mixtures containing (a) fatty acid-N-alkyl polyhydroxyalkylamides and (b) fatty alcohols or fatty alcohol alkoxylates with gaseous sulfur trioxide or chlorosulfonic acid in the absence of inert solvents and then neutralizing the reaction product with bases. The mixtures show excellent surface-active properties and are suitable for a number of applications.
