    Abstract: Demulsifiers containing an anionic surfactant selected from alkylsulfosuccinates, alkylphosphonic acids, and their salts; a nonionic surfactant selected from ethylene oxide/propylene oxide copolymers, ethoxylated fatty acids of polyethylene glycol, terpene alkoxylates, and modified alkanolamides; and solvent bases comprising blends of dibasic esters. Methods for breaking emulsions using such demulsifiers and solvent bases are also disclosed.
