1. A dual phase composition for treating a hydrocarbon stream, said dual phase composition comprising an oil phase and an aqueous phase, said oil phase comprising a primary emulsion breaker, said primary emulsion breaker comprising: 1) a C4-C12 alkyl phenol-formaldehyde resin alkoxylate and 2) an oil-soluble surfactant, wherein said oil-soluble surfactant is a polyalkylene oxide triblock polyol that is less than about 50% ethylene oxide by weight and has an average molecular weight, Mw, less than about 6,000 g/mol, wherein 1) is present in an amount of about 90-50% by weight based upon a combined weight of 1) and 2) and said oil-soluble surfactant 2) is present in an amount of about 10-50% by weight based upon a combined weight of 1) and 2), said oil soluble surfactant 2) also present in an amount of 5-40% by weight based upon the weight of said oil phase and wherein the weight percentage of said oil phase in said dual phase composition ranges from about 70 wt % to about 99 wt %, wherein said oil phase and said aqueous phase form a colloidal inverse micellar solution.
