Fatty acid esters of hydroxyalkylsulfonates and fatty acid amides of aminoalkylsulfonates are prepared by heating an excess of the fatty acids with the sulfonate until the water of condensation is removed. The excess fatty acid is removed by distillation and the isolated fatty acid ester or amide product is directly and rapidly cooled to minimize decomposition and color degradation.
