The invention meets the needs above by providing a surfactant system, mixture or blend that can be used as a part of a soaking composition. The surfactant system is capable of forming emulsions with, and thus removing, oily and greasy stains. In a preferred embodiment the surfactant compositions of the invention can remove non-trans fat and fatty acid stains. The invention involves foaming soaking compositions that have some or part of the anionic surfactant present in the same replaced with an extended chain anionic surfactant.
本发明通过提供一种可用作浸泡组合物一部分的表面活性剂体系、混合物或混合 物来满足上述需求。该表面活性剂体系能够与油性和油脂污渍形成乳液,从而去除油性和油脂污渍。在一个优选的实施方案中,本发明的表面活性剂组合物可以去除非反式脂肪和
脂肪酸污渍。本发明涉及发泡浸泡组合物,其中部分或部分阴离子表面活性剂由延链阴离子表面活性剂取代。
