Hazardous Substance(s) CAS NO % (w/w)
Corexit was reformulated again as the new and improved Corexit 9527, now with up to *38%* super-strength neurotoxin 2-butoxyethanol. But hey - why stop there?
Currently used in the Gulf of Mexico: COREXIT(R) EC9527A with a whopping 30 - 60% by weight of your favorite mutagen and hepatotoxic insecticide 2-butoxyethanol. Exxon was pretty much able to weasel out of any health and environmental testing so it's just never *been* tested at any strength, even back in the whimpy 13% Inopol days.
2-Butoxyethanol 111-76-2 30.0 - 60.0
Organic sulfonic acid salt Proprietary 10.0 - 30.0
Propylene Glycol 57-55-6 1.0 - 5.0
3. HAZARDS IDENTIFICATION
http://www.cleancaribbean.org/docs/COREXIT_EC9527A_UsCuEg.PDFBut both oil and oil spill dispersants are known to cause a variety of health effects in animals, she added, "including death and a variety of sublethal impacts including reduced growth, reproduction, cardiac dysfunction, immune system suppression, carcinogenic, mutagenic and teratogenic effects and alterations in behavior."
Lisa Jackson, EPA, said that Corexit is at most one-tenth "as toxic as oil."
