Fund Project: The project was supported by the National Natural science Foundation of China, Project No. 29733110.

The interesting phenopmena of two aqueous phases coexisting in dilute aqueous solutions of sodium undecenoate-dodecyltrimethylammonium bromide mixture and sodium laurate-dodecyltrimethylammonium bromide mixture were investigated. Vesicles existing in both phases were shown by TEM images. The vesicles are dispersed in lower phase and flocculated in upper phase. Multilamellar structure of vesicles was found in the upper phase of sodium laurate-dodecyltrimethylammonium bromide system.
- Vesicular aqueous two phase,
- catanionic surfactants,
- sodium carboxylates,
- alkyltrimethylarnmonium bromide
