The submicroscopic emulsion droplets were analyzed using the method of capillary hydrodynamic fractionation after the emulsion was passed through a glass microfiber filter with a pore size of 1.5 𝜇𝑚. 50 𝜇𝐿 of the filtered sample were injected through the sample port to an eluent stream followed by the equal amount of marker solution. A standard retention time of 10 min was used for analyzing all the samples reported in this study. Solubility of Surfactants in different solvents. Known quantities of the surfactants were dissolved in the solvents individually in increasing concentration, until further dissolution is thwarted. This surfactant saturated oil was sealed and shaken vigorously in an orbital shaker for 5 min and then stored in the dry air purged environment for 15h. This solvent mixture was then filtered through a 1micron pore size, Whatman filter and then analyzed in UV-Vis spectroscopy. The calibration plot for the concentration of the surfactant as a function of absorbance value in the respective solvent are described in our previous publication . The point of intersection of the slopes of the region where there is change in the absorbance to the saturated region gives the direct measure of the equilibrium solubility of the surfactant mixture in the corresponding solvent.
