Abstract:

The properties of the vesicles from triethanolamine dilaurate (ZRNC_2) which possesses the characteristics of both nonionic and ionic surfactants in the diluted solution of hydrochloric acid have been studied. It, is shown that the vesicles are not formed until the PH value of the solution is lower than 4.2, the vesicle the aqueous solution with and without NaCl has the best stability within pH=23 range These phenomena are due to the partial transformation of2RNC2 into chloride salt of triethanolamine dilaurate.

Key words: Surfactants with double chains, Vesicles, Vesicle stability
