Salt-free ion-paired catanionic amphiphiles of the C-m(+) C-n(-) type, with a high solubility mismatch (n >> m or m >> n) display a remarkable phase behavior in water. A temperature-driven vesicle-to-micelle transition in the dilute side together with a coexistence of two lamellar phases oil the concentrated side is one of the peculiar effects that have been reported for the hexadecyltrimethylammonium octylsulfonate surfactant, C16C8 or TA(16)So(8) (extensive to C14C8 and C12C8).
