Mixed micelles of binary surfactant mixtures Tween 40 - Na-3,12-dioxo-5β-cholanate and Tween 80 - Na-3,12-dioxo-5β-cholanate and their thermodynamic description and characterization

- Developed a procedure for testing the applicability of RST.
- RST approximately with the βij can suggests on stability of mixed micelle.
- Mixed micelles T80-3,12-DOC are characterized with asymmetric GijE.
- Mixed micelles T40-3,12-DOC are mainly characterized with symmetric GijE.
- Mixed micelles T40-3,12-DOC are more stable than mixed micelles T80-3,12-DOC.
