The polymerization stability and the chemical stability and the water resistance of resin films are improved. A surfactant composition according to an embodiment contains a surfactant (A) represented by general formula (1) and an anionic surfactant (B) having a hydrophobic group different from that of the surfactant (A). In the formula, Rrepresents one or two groups selected from groups below, Drepresents a polymerizable unsaturated group represented by chemical formula D-1 or D-2 below, Rrepresents a hydrogen atom or a methyl group, m1 and m2 represent 1 to 2, Arepresents an alkylene group with 2 to 4 carbon atoms, and m3 represents 1 to 100. 

Surfactant composition

The polymerization stability and the chemical stability and the water resistance of resin films are improved. A surfactant composition according to an embodiment contains a surfactant (A) represented by general formula (1) and an anionic surfactant (B) having a hydrophobic group different from that of the surfactant (A). Rrepresents an alkyl group with 8 to 14 carbon atoms, A represents an alkylene group with 2 to 4 carbon atoms, and n representing an average number of moles of an oxyalkylene group added represents 1 to 100.
