PHASE REVERSAL IN EMULSIONS
Abstract
Phase reversal with the aid of univalent cations has been studied in emulsions stabilized by alkali oleates. It was established that the critical concentration of salts, which precedes phase reversal, is a practically constant value, which does not depend on the properties and the concentration of soap, or on the nature of the electrolyte added, with a cation common with the soap. It was proved that conversion of o/w to w/o emulsions takes place when the solvation of the hydrocarbon chains of the stabilizer molecules exceeds the hydration of the polar groups. When hydration of polar groups predominates, conversion of w/o to o/w emulsions takes place.
