(57) [Summary] (Modified) [Problem] Does not contain a phenyl ether group such as a nonylphenyl group, which is considered to have a large impact on the environment, and has the same performance as a reactive surfactant containing a phenyl ether group. To provide a surfactant having. SOLUTION: The following general formula (1) or (2) [R 1 is a branched aliphatic hydrocarbon group or a secondary aliphatic hydrocarbon group, R 2 is an alkylene group, R 3 is H or a methyl group, A O and AO 'are C2-C4 oxyalkylene groups, M is H, an alkali metal, an alkaline earth metal or ammonium (alkaline earth metal is 1/2), and m and n are 0 to 0. Number of 100, a and b are numbers of 0 or 1. ] The reactive surfactant represented by these. |
