MES(或a—SF)是受当今国内外密切关注的最有发展潜力的廉价高效表面活性剂和钙皂分散剂，其有优良的去污性、抗硬水性、低刺激性和毒性，表面活性优于烷基苯磺酸钠（LAS），是国际上公认的用来替代烷基苯磺酸钠的第三代表面活性剂。
阴离子表面活性剂中还同时包括脂肪酸甲酯磺酸盐，其加入量为各组分重量百分比总和的1 ~ 10%。
The anionic surfactant also contains the fatty acid methyl ester sulfonate with the added amount of 1-10 percent of the total sum of the weight percentages of the components.
但是，早期研究脂肪酸甲酯磺酸盐生产的成果不理想，产品色泽深，从原料甲酯（ME）到MES的收率也低。
However, early efforts to manufacture MES resulted in products with high color and low conversion of methyl ester(ME)feedstock to MES.
