<p>A surfactant composition which contains an anionic surfactant, has a good handleability even in the case of a high surfactant content, is easy to handle at room temperature, and has a low viscosity. The composition comprises (a) a nonionic surfactant represented by the general formula (1) and (b) an anionic surfactant in a weight ratio of (99:1) to (10:90): RO-(EO)x-(PO)y-(EO)x'-H, wherein R represents an alkyl group having 8 to 20 carbon atoms; EO represents an oxyethylene group; PO represents an oxypropylene group; x and x' are each a number of 1 or more; and y is a number of more than 0 and less than the sum of x and x', provided that (EO)x, (PO)y, and (EO)x' are bonded in a block form in that order.</p> |
