二聚表面活性剂是由两个双亲体通过一个间隔链连接构成的。二聚表面活性剂表现出了与传统的单链表面活性剂不同的性质。例如，它能够更有效地降低表面张力以及更有效地形成胶束。其对应的C20值和CMC值大约分别比相应的单链离子型表面活性剂小三个数量级和两个数量级。

The dimeric surfactants are a novel class of surfactants which have two amphiphiles connected with a spacer.This linking leads to changes in the physical and chemical properties as compared with those of the conventional single-chain surfactants.For example,the ionic dimeric surfactants are about 3 orders of magnitude more efficient in reducing surface tension(C20) and somewhat more than 2 orders of magnitude more efficient in forming micelle(CMC) than conventional ionic surfactants.These properties suggest that dimeric surfactants may be candidates for the next generation of surfactants.In this article we mention the interfacial properties at the air/water interface and the characteristics of micelle and summarize the synthesis and several potential applications in industrial and household fields.
