Abstract:
A method for dispersing a petrochemical spill on a body of water, comprising:providing a dispersant which contains about 35 to about 85 percent by weight of an oil-soluble surfactant combination of a type and in a quantity to form a mixture with petrochemical for the spill, the oil-soluble surfactant combination comprising a plurality of oil-soluble surfactants which are each non-ionic and have a different hydrophilic and lipophilic balance, the oil-soluble surfactant combination including poly ethylene glycol mono-oleate, about 8 to about 32 percent by weight of at least one water-soluble surfactant of a type and in a quantity to emulsify the mixture with water from the body of water, said at least one water-soluble surfactant comprising cocoamide, about 4 to about 16 percent by weight of a co-solvent for coupling the mixture with the water-soluble surfactant to help emulsify the petrochemical into the body of water, and about zero to about 50 percent by weight water; and supplying an effective amount of the dispersant onto the body of water at the spill, for dispersing the spill by emulsifying at least some of the petrochemical into the body of water.
