Abstract
A fluorine-containing compound exhibiting excellent surface tension-reducing ability despite the absence of perfluoroalkyl group having a chain length of 8 or more which had been the cause of the PFOS and PFOA problems and use of a fluorine material with low environmental load is provided. Also provided are a fluorine-containing surfactant and a composition thereof, an aqueous resin emulsion and a floor polish composition containing such surfactant. The fluorine-containing compound is represented by the following formula (1): Rf—CH—CH(OH)—CH—NR—CH—(O)—SOM (1) wherein Rfis a Cperfluoroalkyl group, p, q, and r are independently an integer of 1 to 6, M is a cationic atom or atomic group, n is 0 or 1, R is hydrogen atom, a Calkyl group, or a group represented by the following formula (2):Rf—CH—CH(OH)—CH—  (2)wherein Rfis a Cperfluoroalkyl group, and s and t are independently an integer of 1 to 6.
