ABSTRACT:
A high concentration aqueous solution of the salt of an alpha-sulfo fatty acid ester is produced by (a) neutralizing the sulfonated product of a fatty acid ester with an aqueous caustic alkali solution having a concentration of 15 through 50% by weight, in the presence of an alcohol having 1 to 4 carbon atoms in an amount of 5 through 20% by weight based on the weight of the sulfonated product, to form an acidic neutralized product having a pH of 2.5 through 4 and; then, (b) adding an aqueous caustic alkali solution having a concentration of 1 through 5% by weight to the acidic neutralized product to adjust the pH of the acidic neutralized product to 6 through 7. The aqueous solution of the salt of the alpha-sulfo fatty acid ester thus obtained includes only small amounts of the undesired alpha-sulfo fatty acid salt.
