CompositionIt combines a predominantly oil-soluble surfactant (such as polyethylene glycol mono-oleate) with a predominantly water-soluble surfactant (such as cocoamide) and a co-solvent for coupling a mixture of the predominantly oil-soluble surfactant and the oil.[2] AlternativesAlternative dispersants which are approved by the EPA are listed on the National Contingency Plan Product Schedule[3] and rated for their toxicity and effectiveness.[4] Deployments2010 Gulf of Mexico oil spillDispersit is unique among U.S. Environmental Protection Agency-rated dispersants in being the only one rated as 100% effective against South Louisiana crude oil, and it is among the least toxic, according to EPA tests.[4] By comparison, Corexit, the oil dispersant used in the Deepwater Horizon oil spill, is rated at 54.7% effective against South Louisiana crude oil and three times as lethal to silverfish and more than twice as lethal to shrimp.[5] On May 20, US Polychemical Corporation was reported to have received an order from BP for Dispersit SPC 1000.[6] US Polychemical reportedly stated it was able to produce {{convert|20,000|USgal|l}} a day in the first few days and increasing up to {{convert|60,000|USgal|l}} a day thereafter.[7] See also
