摘要
The kinetics of formation of vesicles by dilution with water from a hydrotrope solution of the vesicle forming surfactants and the reverse formation of them to hydrotrope stabilized micelles were investigated using the stopped how technique. The relaxation time for the formation of vesicles varied from 0.09 s to several seconds depending on the concentration of the vesicle forming surfactant, while the corresponding time for the formation of hydrotrope stabilized micelles from the vesicular solution was found to be 0.24 s irrespective of the concentrations involved.
