Abstract In the present work the dynamics of surface (at the aqueous solution/air interface) and interfacial (at the aqueous solution/n-decane interface) tensions were studied for diluted aqueous solutions of dialkyldimethylammonium bromides with alkyl chain lengths of 10 and 12 carbon atoms. These amphiphiles form different kinds of bilayer aggregates in aqueous systems, such as small unilamellar vesicles, multilamellar liposomes and random lamellar L3 phases, depending on the surfactant concentration. Dynamic tension measurements were performed by drop weight and drop volume methods. It was found that the rate and the character of surface tension equilibration is strongly dependent on surfactant concentration. The data obtained were analysed on the basis of modern theoretical conceptions and the diffusion coefficient values were estimated using the approach developed by Fainerman et al. (Colloids Surfaces A: Physicochem. Eng. Aspects, 87 (1994) 61).
