A U.S. Air Force Reserve plane sprays Corexit over the Deepwater Horizon oil spill in the Gulf of Mexico. Corexit [1] (often styled COREXIT) [2] is a product line of oil dispersants used during oil spill response operations. It is produced by Nalco Holding Company, an indirect subsidiary of Ecolab. [3]
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]
Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
The BP (BP) oil spill may be over, but controversy over the company's use of toxic oil dispersants in the Gulf of Mexico is still going strong. Although BP allegedly stopped using the chemicals ...
This had never previously been tried but due to the unprecedented nature of this spill, BP along with the USCG and the EPA, decided to use "the first subsea injection of dispersant directly into oil at the source". [40] Dispersants are said to facilitate the digestion of the oil by microbes. Mixing the dispersants with the oil at the wellhead ...
Discussing the dispersants used in the spill, Shaw said that they can be more toxic than either oil or solvent alone because dispersants contain solvents that facilitate rapid entry of oil into cells and organs, She stated that "over time, PAH metabolites can be eliminated from the body, but even brief exposure during critical life stages may ...

The first National Contingency Plan was developed and published in 1968, in response to a massive oil spill from the oil tanker Torrey Canyon, off the coast of England a year earlier. More than 37 million gallons of crude oil spilled into the water and caused massive environmental damage. To avoid the problems faced by response officials ...
