Abstract

We investigated the kinetics of solubilization of triglycerides (triolein and soybean oil) by observing the diminishing of individual oil drops (radius ≤ 50 μm) in a micellar surfactant solution. We used two solubilization cells. Cell no. 1 is a centimeter-sized thermostated vessel, containing the investigated micellar solution and a few oil drops. Cell no. 2 represents a set of horizontal glass capillaries filled with the solution; in each of them an oil drop was injected by a syringe. Cell no. 1 is more easy to operate, whereas cell no. 2 allows a quantitative interpretation of the results. We carried out experiments with solutions of two nonionic surfactants and investigated the effect of various additives on the solubilization rate. The addition of an anionic surfactant is found to suppress the solubilization due to an enhanced electrostatic repulsion between the micelles and the oil−water interface. This inhibitory action can be partially removed by addition of an amphoteric surfactant. Highest solub...
