Abstract
A process for preparing alkoxylated alkyl glyceryl ether sulfonates which comprises reacting in the presence of water and the absence of ethanol a mixture of alkoxylated glycidyl ethers having as the major quantity of alkoxylated material ##STR1## with a salt of a sulfite bisulfite salt mixture at a temperature below about 110.degree. C. wherein R is an alkyl or alkenyl of 10 to 20 carbon atoms, inclusive, R' is hydrogen or methyl and n has an average value of 1 to 10 and obtaining a sulfonated alkoxylated product having as a major quantity of the alkoxylated material a salt of R(OCH.sub.2 CHR.sup.1).sub.n OCH.sub.2 CHOHCH.sub.2 SO.sub.3 --
