ABSTRACT:
A powdered detergent composition comprising a nonionic surfactant as the main surfactant, which comprises (a) a polyoxyethylene alkyl ether, wherein the alkyl group has 10 to 20 carbon atoms on the average and the average molar number of ethylene oxide added is 5 to 15, in an amount of 12 to 35% by weight based on the total weight of the composition, (b) a lipolytic enzyme in such an amount that the lipolytic activity per gram of component (a) would be 0.1 to 500 LU, (c) an anionic surfactant in an amount of 1.0 to 7.0% by weight based on the total weight of the composition and (d) an alkaline material in an amount of 5 to 35% by weight based on the total weight of the composition, and of which a 0.1% by weight aqueous solution has a pH exceeding 9.0, is excellent in detergency on oily soils such as subum soil.
