<p>A surfactant composition which, even when a surfactant is incorporated in a relatively high concentration, exhibits a high capability of wetting, a high penetrability into, and a high detergency against an object to be washed. The composition comprises the following compound (1) RO-(EO)x-(PO)y(EO)x'-H, having an average molecular weight of not more than 1200 and water, and the amount of the compound (1) based on the total amount of water and the compound (1) is 5 to less than 50 % by weight. In said compound (1), R represents an alkyl group having 12 to 15 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 0.5 to 6, provided that (EO)x, (PO)y, and (EO)x' are bonded in a block form in that order.</p> |
