A formulation of chemical surfactants, solvents and inorganic salts is effective for dispersing heavy oils in both salt and fresh water. The formulation comprises a mixture of a sorbitan ester of an aliphatic monocarboxylic acid, a polyoxyethylene adduct of a sorbitan monoester of an aliphatic monocarboxylic acid, an alkali metal salt of a dialkyl sulfosuccinate, a polyoxyethylene adduct of a sorbitan triester of a monocarboxylic acid, a solvent comprising a hydrocarbon and/or a glycol ether and an inorganic salt containing a soluble divalent cation such as calcium or magnesium.
