Abstract: A process for preparing bi-modal water emulsions is disclosed comprising: I) forming a mixture comprising; A) 100 parts by weight of a hydrophobic oil, B) 1 to 1000 part by weight of a water continuous emulsion having at least one surfactant, II) admixing additional quantities of the water continuous emulsion and/or water to the mixture from step I) to form a bi-modal emulsion.

Abstract: An effective and non-toxic oil spill dispersant combines a predominately oil-soluble surfactant (eg., polyethylene glycol mono-oleate) with a predominately water-soluble surfactant (eg., cocoamide) and a co-solvent for coupling a mixture of the predominately oil-soluble surfactant and the oil spill, with the predominately water-soluble surfactant. Water is included in the combination to help advance the interaction between the predominately oil-soluble surfactant and the predominately water-soluble surfactant as well as the co-solvent. The water component also helps reduce the viscosity of the dispersant to allow it to be pumped under pressure.
