Abstract

A mixture of sodium salts of fatty acids is synthesized in the form of a 20% solution via the alkaline hydrolysis of triglyceride components of hemp oil. IR spectroscopy data confirm the complete hydrolysis of ester groups and the presence of carboxylate groups characteristic of sodium salts of fatty acids. The physicochemical properties of the obtained composition and their micelle-forming characteristics are studied using a Wilhelm plate at the air–water interface, in combination with conductometry and spectrophotometry in aqueous solutions. It is shown that the synthesized composition has strong surface activity which form mixed layers from its components at the air/water interface and in surfactant micelles. Three stages of aggregation of the synthesized product in aqueous solutions are discovered: premicellar association, the formation of micelles, and changes in the structure of micelles. The solubilizing capability of micellar systems based on the synthesized product is assessed the using the example of Sudan III dye.
