    • 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.
    • 一种包含非离子表面活性剂作为主要表面活性剂的粉末洗涤剂组合物,其包含(a)聚氧乙烯烷基醚,其中所述烷基具有10至20个碳原子,平均加入的环氧乙烷的平均摩尔数为5至15, (b)一种脂肪分解酶,其量使得每克组分(a)的脂肪分解活性为0.1至500LU,(c)按照组合物的总重量计为12至35重量% 基于组合物的总重量为1.0-7.0重量%的阴离子表面活性剂和(d)基于组合物总重量的5-35重量%的碱性物质,其中 0.1重量%的水溶液的pH值超过9.0,对油土如土壤土的去污力优良。
