A mixture of sodium salts of fatty acids in the form of a 20% solution was synthesized via alkaline hydrolysis of the triglyceride components of hemp oil. IR spectroscopy confirmed complete hydrolysis of the ester groups and the presence of carboxylate groups characteristic of sodium fatty acid salts. The physicochemical properties of the resulting composition and its micelle-forming characteristics were studied using the Wilhelmy plate method at the air/water interface, as well as conductometric and spectrophotometric methods in aqueous solutions. It was shown that the synthesized composition exhibits high surface activity, forming mixed layers of its components both at the air/water interface and in surfactant micelles. Three stages of aggregation of the synthesized product in aqueous solutions were identified: premicellar association, micelle formation, and micelle structural transformation. The solubilizing capacity of micellar systems based on the synthesized product was evaluated using the dye Sudan III as a model.
