What is Corexit dispersant?
Information for Health Professionals. Overview. Dispersants are specially designed oil spill products that are composed of detergent-like. surfactants in low toxicity solvents.
Is Corexit still used?
COREXIT 9500 is the chemical dispersant currently being used in the Gulf in attempts to remedy the Deep Water Horizon spill. It is produced by the Nalco company and they have sold at least $40 million of the product to BP.
Is Corexit 9500 toxic?
Our results indicate that Corexit 9500A is highly toxic to microzooplankton, particularly to small ciliates, and that the combination of dispersant with crude oil significantly increases the toxicity of crude oil to microzooplankton.
Who manufactures Corexit 9500?
Nalco
The BP response team has used two different versions, Corexit 9527 and Corexit 9500. The former is an acute health hazard, according to the EPA. It’s an eye and skin irritant that could also harm the red blood cells, kidney and liver. Nalco says it’s been deploying only Corexit 9500 since late April.
How does Corexit 9500 work?
Chemical dispersants contain a mixture of chemicals designed to break up an oil slick by reducing the interfacial surface tension of the oil, causing it to form micron-sized droplets. These droplets can then be diluted in the water column preventing the formation of a surface slick.

Why are oil dispersants bad?
Dispersants and dispersed oil are particularly toxic to corals, leading scientists to call for a ban on dispersant use near coral reefs. Dispersants and dispersed oil harm the early stages of corals by increasing death rates, reducing settlement on reefs, and altering behavior.
What is dispersant used for?
A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping.
What are the disadvantages of oil dispersants?
Does Corexit 9500 have toxic effects on daphnids?
These results indicate that Corexit 9500 has toxic effects on daphnids, particularly during the neonatal developmental stage, which is consistent with marine zooplankton results, whereas juvenile hormone-like activity was not identified.
