ABSTRACT:
Aqueous solutions of surface-active hydroxysulfonates are obtained by reaction of unsaturated fatty alkenyl or fatty alkenyl polyalkoxyl esters, for example of oleyl acetate or oleyl polyethoxyl acetate, with sulfur trioxide, introduction of the reaction product into aqueous alkali metal, alkaline-earth or ammonium hydroxide and heating of the solutions until the ester and sultone groups present have been hydrolyzed.
