Abstract:

The phase transition and microenvironment properties of the vesicles from tri-ethanolamine dilaurate(2RNC_2) in the diluted solution of chloride acid have been studied by means of DSC and fluorescence method. It is shown that the micropolarity of the vesicles increased with the decrease of the pH value of the solution, but the phase transition temperature, microviscosity of the vesicles approached the maximum values within pH 23 range. The foaming ability of the solution also reached the best effect within the same pH range.

Key words: Vesicles, Phase transition temperature, Micropolarity, Microviscosity, Foaming ability
