где R1 представляет Н, углеводород, 2-гидроксиэтил, 2-гидроксипропил или их смеси, R2 представляет С5-С3 1 углеводород, а Z является полигидроксиуглеводородом, содержащим линейную углеводородную цепочку, содержащую по крайней мере три гидроксильные группы, непосредственно присоединенные к цепи, или их алкоксилированные производные; одно или более дополнительных неионных поверхностноактивных соединений, причем весовое отношение полигидроксиамида жирной кислоты к дополнительным неионным поверхностно - активным соединениям находится в интервале от около 1 : 5 до около 5 : 1. Настоящее изобретение обеспечивает также стиральные детергентные композиции, которые содержат описанные ранее неионные поверхностно - активные системы. Если их включают в такие стиральные детергентные композиции, то неионные поверхностно - активные системы неожиданно повышают эффективность удаления жировых (масляных) пятен в широком интервале условий стирки. Кроме того, настоящее изобретение обеспечивает повышение эффективности удаления пятен детергентными композициями за счет введения в такие композиции описанных выше неионных поверхностно - активных систем.The present invention provides a non-ionic system of surface-active compounds, which includes: one or more polyhydroxy fatty acid amides of the formula:
where R 1 is H, hydrocarbon, 2-hydroxyethyl, 2-hydroxypropyl or mixtures thereof, R 2 is a C 5 -C 3 1 hydrocarbon, and Z is a polyhydroxy hydrocarbon containing a linear hydrocarbon chain containing at least three hydroxyl groups directly attached chain, or their alkoxylated derivatives; one or more additional non-ionic surface-active compounds, the weight ratio of the polyhydroxy fatty acid amide to the additional non-ionic surface-active compounds being in the range of from about 1: 5 to about 5: 1. The present invention also provides washing detergent compositions which contain active systems. If they are included in such washing detergent compositions, non-ionic surface-active systems unexpectedly increase the efficiency of removing fatty (oil) stains in a wide range of washing conditions. In addition, the present invention provides improved stain removal with detergent compositions by introducing the nonionic surface - active systems described above into such compositions.
