    • The present invention provides nonionic surfactant systems comprising: (a) one or more polyhydroxy fatty acid amides having formula (I), wherein R is H, a C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, or mixtures thereof, R is a C5-C31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least three hydroxyl groups directly connected to the chain, or an alkoxylated derivative thereof; and (b) one or more additional nonionic surfactants; wherein the weight ratio of polyhydroxy fatty acid amide (a) to additional nonionic surfactant (b) is in the range of from about 1:5 to about 5:1. The present invention also provides laundry detergent compositions which contain the nonionic surfactant systems described above. When included in such laundry detergent compositions, these nonionic surfactant systems unexepctedly improve the stain removal performance of such compositions against greasy/oily stains across a broad range of laundry conditions. This invention further provides a method for improving the stain-removing performance of detergent compositions by incorporating into such compositions the nonionic surfactant systems described above.
    • 本发明提供了非离子表面活性剂体系,其包含:(a)一种或多种具有式(I)的多羟基脂肪酸酰胺,其中R 1是H,C 1 -C 4烃基,2-羟基乙基,2-羟基丙基或 其混合物,R 2为C 5 -C 31烃基,Z为具有至少三个直接与该链连接的羟基的直链烃基链的多羟基烃基或其烷氧基化衍生物; 和(b)一种或多种另外的非离子表面活性剂; 其中多羟基脂肪酸酰胺(a)与另外的非离子表面活性剂(b)的重量比在约1:5至约5:1的范围内。 本发明还提供了含有上述非离子表面活性剂体系的衣物洗涤剂组合物。 当包括在这种洗衣洗涤剂组合物中时,这些非离子表面活性剂体系无法改善这种组合物在宽范围的衣物条件下对油腻/油性污渍的去污性能。 本发明进一步提供一种通过将这种组合物掺入上述非离子表面活性剂体系来提高洗涤剂组合物的去污性能的方法。
