    Abstract: A water-in-oil emulsion is disclosed which comprises:(A) a continuous oil phase;(B) a discontinuous aqueous phase;(C) a minor emulsifying amount of at least one salt derived from (C)(I) at least one hydrocarbyl-substituted carboxylic acid or anhydride, or ester or amide derivative of said acid or anhydride, the hydrocarbyl substituent of (C)(I) having an average of from about 20 to about 500 carbon atoms, and (C)(II) at least one amine; and(D) a functional amount of at least one water-soluble, oil-insoluble functional additive dissolved in said aqueous phase; with the proviso that when component (D) is ammonium nitrate, component (C) is other than an ester/salt formed by the reaction of polyisobutenyl (Mn=950) succinic anhydride with diethylethanolamine in a ratio of one equivalent of anhydride to one equivalent of amine.
