The Spontaneous Emulsification of Mixtures of Oleic Acid and Paraffin Oil in Alkaline Solutions

Abstract

Interfacial tension values occurring during the transfer of oleic acid from paraffin oil to aqueous alkali have been determined by the sessile-drop method. It is postulated that the ease of emulsification observed with these systems arises from the nature of the changes In interfacial tension associated with the transfer.
