Thermodynamic and kinetic stability. Properties of micelles and vesicles formed by the decanoic acid/decanoate system

The dialysis of micellar and vesicular systems, through a cellulose acetate membrane permeable only to monomer surfactant, has been investigated for the system sodium decanoate/decanoic acid as a function of pH, in pH regions where micelles (pH 9) or vesicles (pH 7.5) are present. The results provid...
