Abstract

The invention relates to a process for the production of concentrated mono- and/or disalt dispersions of .alpha.-sulfofatty acids by sulfonation of saturated fatty acids and/or fatty acid mixtures with sulfur trioxide, surfactants being added during the neutralization stage to improve the flowability of the dispersions.
