Abstract

Self-division of a mineral oil-fatty acid droplet placed in an alkaline solution was investigated. The initially homogeneous mineral oil droplet containing various amounts of 2-hexyldecanoic fatty acid underwent a division process resulting in the formation of two droplets. One formed ('daughter') droplet contains middle-phase microemulsion (surfactant-rich phase), while the other contains mineral oil with 2-hexyldecanoic acid (surfactant-low organic phase). We found that the pH of the water phase has negligible effect on the ratio of the sizes of the 'daughter' droplets. However, the contact angle between two droplets highly depends on the pH of the alkaline solution.
