If you're talking about the "evil dispersant" CoRexit 9500, then you have nothing to worry about. Its ingredients are pretty innocuous.
A list of the ingredients of CoRexit 9500 and some common uses in consumer products:
Sorbitan, mono-(9Z)-9-octadecenoate....Skin cream, body shampoo, emulsifier in juice
Sorbitan, mono-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs....Baby bath, mouth wash, face lotion, emulsifier in food
Sorbitan, tri-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs.....Body/Face lotion, tanning lotions Butanedioic acid, 2-sulfo-, 1,4-bis(2-ethylhexyl) ester, sodium salt (1:1).....Wetting agent in cosmetic products, gelatin, beverages
Distillates (petroleum), hydrotreated light....Air freshener, cleaner
The main reason that the eco-freaks are bad-mouthing the dispersant is that it "is" toxic to aquatic species. The surfactants in it coat gills and gill equivalents and interferes with their ability to get oxygen from the water.
That's a big IF! Maybe I am, maybe I'm not. Who knows for sure what they injected?
What ever it was the oil brought it to the surface.
rawcat, don’t believe wonder. Do your own research. He’s getting his info from Nalco.

BP deliberately sinks oil with Corexit as cover up
BP’s massive oil spill will officially become the largest ever in the Gulf of Mexico this week. The volcanic oil that’s gushed for two and a half months will surpass the 140 million gallon mark, surpassing the record-setting Ixtoc I spill off Mexico’s coast from 1979 to 1980. Meanwhile, In a stunning interview with CNN’s Anderson Cooper on June 29th, Allegiance Capitol Corporation V.P. Fred McCallister is claiming that BP is deliberately sinking oil with the toxic chemical dispersant Corexit, to hide the extent of the oil spill. By sinking the oil before it can be collected, BP won’t have to pay fines on it.
http://www.thomhartmann.com/forum/2010/07/bp-deliberately-sinks-oil-corexit-cover
The two versions of Corexit [Corexit 9500 and Corexit(R) EC9527A] believed to be in BP’s secret formula both contain 2-butoxyethanol, a substance known to cause headaches, vomiting and reproductive problems at high doses. According to the U.S. Coast Guard, one of these substances may:
• Cause moderate irritation and be harmful if absorbed through skin.
• Be harmful if swallowed, causing liver and kidney effects and/or damage. There may be irritation to the gastro-intestinal tract.
• Cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects from excessive exposure.
• Cause injury to red blood cells (hemolysis), kidney or the liver from repeated or excessive exposure.
It is easy to recognize BP’s underwater oil fountain as an environmental catastrophe, but human health is likely to be affected as well. Because of the dangers that both crude oil and chemical dispersants may pose to the liver, people with chronic liver disease are urged to take additional precautions if visiting the Gulf Coast this summer.
http://www.liversupport.com/wordpress/2010/06/will-recent-oil-spill-impact-those-with-liver-disease/
The main ingredients of Corexit is 2-Butoxyethanol which can make up to 60% of the dispersant and is known to be toxic to blood, kidneys, liver, and the central nervous system (CNS).
2-Butoxyethanol is also known to cause cancer, birth defects and has been found to cause genetic mutations and is a delayed chronic health hazard as well as an environmental hazardous material
Corexit also contains Arsenic, Cadmium, Chromium, Mercury, and Cyanide.
How effective is Corexit in dispersing Gulf crude?
Corexit 9500 is only 54.7% effective and Corexit 9527A is 63.4% effective in dispersing the crude oil found off the shores of South Louisiana.
BP has sprayed both Corexit 9500 and Corexit 9527 into the Gulf of Mexico to disperse the oil both of which have been banned in the UK since 1998 for failure to pass the Rocky Shores Test.
By BP’s own admission Corexit has the potential for bioaccumulation meaning it has the potential to accumulate in the tissues of organism beginning with the first organism in a food chain.
Why allow the use of these toxic dispersants?
Well the EPA has ordered BP to stop using the dispersants but BP has refused
Instead BP replied with its justification for using Corexit which the EPA responded to saying BP’s response “lacked sufficient analysis and focused more defending your initial decision” .
In general, the EPA justifies the use of dispersants because they are less toxic than oil and the cause less of an environment impact that oil along the coastline calling dispersants an environmental trade off which is the lesser of two evils.
However the choice of using Corexit contradicts both of those justifications.
Corexit is lethal in as little as 2.6 parts per million where oil is lethal in 11 parts per million meaning that Corexit is over 4 times more toxic than oil.
Furthermore scientific studies show that oil dispersed with Corexit is 11 times more lethal than oil alone.
In fact the study referenced showed that crude oil was lethal at 4250 parts per million to killifish but combination of oil mixed with Corexit was lethal in as little as 317.7 ppm.
“Dispersed oils were more toxic than crude oils,” noted the report.
The other justification of lessening the environmental impact along the shoreline doesn’t hold up either as the reason Corexit was banned in the UK is because it was in fact shown to have a “significant deleterious ecological change” on the shoreline.
The fact Corexit is 4 times as toxic as oil and up to 11 times as toxic when combined with oil it literally makes no sense to allow the use of such a toxic chemical that can “delete” the ecological systems along the Gulf coast.
A report in the journal Environmental Toxicology a decade ago concluded that lethality levels in “dispersed oil combinations were significantly more toxic to these organisms than .. crude oil.” Another study, this time of snails and amphipods reached exactly the same conclusion.
What are the long term effects of Corexit?
The EPA has stated over and over that the long term effects of the use of Corexit are unknown yet there is plenty of data documenting the long term effects on humans (see below).
Further making the EPA claims questionable is EPA’s Deepwater horizon response sites site clearly states that between 1 million and 2.5 million gallons of the neurotoxin pesticide Corexit was used in the 1979 ixtoc oil spill which makes it unfathomable that the EPA doesn’t know what the long term effects are of a chemical that has been widely used, and eventually banned in certain countries, over a period of 30 years.
To the contrary of the EPA’s statement scientific studies widely state Corexit 9527 has been tested extensively in the laboratory and used on oil spills since 1978 and a considerable number of toxicity reports exist concerning a wide variety of species.
So why does the Federal Government continue to tell us the the long term effects of the dispersant usage are unknown?
Why does the Federal Government continue to pretend like they know so little about the dispersant BP is being used?
What are the chemical components of the dispersants COREXIT 9500 and COREXIT 9527?
While the main ingredient which makes up to 60% of Corexit is reason enough to cause concern.
If you dig any more dirt on these let me know.
The components of COREXIT 9500 and 9527 are:
CAS Registry Number Chemical Name
57-55-6 1,2-Propanediol

You conveniently left out one of the worst ingredients.. Propylene Glycol.
Propylene Glycol
A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage.
and we aren’t talking about trace amounts like in other products. We are talking about close to 2 MILLION gallons of Corexit !!!! MIXED with crude which IS toxic regardless of what lies you try to spread here. Mix the oil, with millions of galllons of Corexit, add the dead and decaying marine life and micro organisms, other things such as fertilizer, pesticide runoffs, etc. in a very warm GOM.... What do you get? Toxic soup. It’s a roll of the dice and it’s untested waters. You don’t have a clue.

co-freaks are bad-mouthing the dispersant is that it “is” toxic to aquatic species.

You ass, you don’t have to be an eco freak to care about “aquatic species”. By aquatic species do you mean Manatees, Dolphins, turtles, fish, shrimp, lobster, crabs, whales, etc. I effing care about them.
