The present invention provides nonionic surfactants, compositions incorporating these surfactants, and related methods of making and using such surfactants and compositions. The nonionic surfactants demonstrate excellent equilibrium and dynamic surface tension properties as well as excellent wetting properties. Further, representative embodiments of the surfactants have shown low foaming characteristics, indicating that the surfactants would be suitable in applications where resistance to foaming is desired. The surfactants can be used singly or in combination with other nonionic and/or ionic surfactants as desired. As an overview, the nonionic surfactants of the present invention have a structure in which the surfactant backbone includes one or more amine moieties. At least one, preferably two or more branched, cyclic, fused cyclic, and/or spyro hydrophobic moieties are pendant from at least one of the amine moieties. Additionally, at least one, preferably two or more hydrophilic moieties, preferably alkylene oxide (i.e., polyether) chains also are pendant from at least one of the amine moieties.
本发明提供了非离子表面活性剂,包括这些表面活性剂的组合物,以及制备和使用这些表面活性剂和组合物的相关方法。这些非离子表面活性剂表现出优异的平衡和动态表面张力性能,以及优异的润湿性能。此外,表面活性剂的代表性实施例表现出低起泡特性,表明这些表面活性剂适用于需要抗起泡性能的应用中。这些表面活性剂可以单独使用,也可以根据需要与其他非离子和/或离子表面活性剂组合使用。总体而言,本发明的非离子表面活性剂具有一种结构,其中表面活性剂骨架包括一个或多个胺基团。至少一个,最好是两个或更多的分支、环状、融合环状和/或螺环疏水基团悬挂在至少一个胺基团中。此外,至少一个,最好是两个或更多的亲水基团,最好是烷氧基(即聚醚)链也悬挂在至少一个胺基团中。
