Abstract

Carbonic acid fatty alcohol ester sulfonates prepared by sulfonation of carbonic acid fatty alcohol esters corresponding to formula I EQU R.sup.1 O--(C.sub.m H.sub.2m O).sub.n --CO--(OC.sub.m H.sub.2m).sub.n --OR.sup.2 (I) in which PA0 R.sup.1 O is a residue of a fatty alcohol containing 16 to 22 carbon atoms and at least one olefinic double bond, PA0 R.sup.2 O is a residue of a saturated alkanol containing 1 to 22 carbon atoms or a residue of a fatty alcohol containing 16 to 22 carbon atoms and at least one olefinic double bond, PA0 m is a number 2 or 3 and PA0 n is a number of 0 to 20, and subsequent neutralization and hydrolysis of the sulfonation products with a base.
