Abstract: The invention relates to a surfactant composition comprising an ionic liquid prepared from an unsubsituted or substituted primary, secondary or tertiary amine, or from an unsubstituted or substituted pyridine, amidine or guanidine with at least one fatty acid and/or resin acid. The invention also relates to a method for treating bitumen froth from a separation process, where bitumen is separated from mineral solids. The method comprises addition of said surfactant composition to the diluent and/or to the froth before phase separation.
