Abstract of the Disclosure The addition products of sulfites and mono- or diesters of maleic acid and long chain fatty alcohols are known to be useful surfactants. The present invention provides a novel surfactant useful in lowering the surface tension of water and as a leveling agent in wax emulsions. The surfactants of the present invention are compounds of the general formula NO-CO-CH2-CH(SO3M)-CO-O-R' in which R is a group of the general formula Rf=(CH2)m-(OCH2CH2)n- wherein Rf stands for a straight-chain or terminally methyl-branched per- fluoroalkyl group of 2 to 8 carbon atoms, m is a number from 1 to 4, n is a number from zero to 3, M is a hydrogen or alkali metal atom or an ammonium group of the formula Hx?R"4-x in which R" is an alkyl group of 1 to 4 carbon atoms which is unsubstituted or substituted by hydroxy, carboxy or sulfo, x is an integer of zero to 4, and R' is defined as R or as M.
