"U.S. EPA has quietly released a full list of ingredients in the two controversial dispersants BP PLC is using to combat the Gulf of Mexico oil spill, following weeks of complaints from members of Congress and public health advocates that the dispersant manufacturer had kept its complete formula a secret from the public.
The mysterious appearance on EPA's website of the specific chemical components in Corexit 9500 and 9527 -- more than 1.1 million gallons of which have been sprayed in Gulf since the disaster began -- came as a surprise to environmental groups as well as to Nalco Holding Co., the producer of the dispersants. Nalco spokesman Charlie Pajor said the company was first informed about the full release of Corexit ingredients by Greenwire, not EPA."
