A surfactant composition having bactericidal properties and capable of mass production at low cost is realized. A surfactant composition includes an anionic surfactant excluding a higher fatty acid salt having 10 to 20 carbon atoms and an alkali metal salt different from an ionic surfactant, Used in the form of an aqueous solution. The anionic surfactant used here is, for example, at least one selected from the group consisting of carboxylate, sulfonate, sulfate ester salt and phosphate ester salt. The alkali metal salt used here is, for example, chloride salt, carbonate salt, bicarbonate salt, hydroxide salt, nitrate salt, sulfate salt, hydrogen phosphate salt, dihydrogen phosphate salt, formate salt and acetate salt. At least one selected from the group consisting of: [Selection figure] None |
