Aggregative stability of emulsions containing walnut oil

Abstract

Phase diagrams of the state of a three-component emulsion – Walnut oil / Aqua / Ethanol were developed. It is shown that walnut oil is more prone to form A/O emulsion than O/A ones, that is possibly explains by the presence of surfactants in it. The aggregate stability of emulsions is also affected by the composition of a water-ethanol phase. The most stable emulsions were those that included practically equal volume fractions of ethanol and water. This fact could be explained by an approximate densities equality of polar (aqua + ethanol) and nonpolar (oil) phases.
