What’s in Corexit — from the Horse’s Mouth

Here’s a list of what is reported to be the chemical components in Corexit:

Chemical Name

  • 1,2-Propanediol
  • Ethanol, 2-butoxy- (only in Corexit 9527)
  • Butanedioic acid, 2-sulfo-, 1,4-bis(2-ethylhexyl) ester, sodium salt (1:1)
  • Sorbitan, mono-(9Z)-9-octadecenoate
  • Sorbitan, mono-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs.
  • Sorbitan, tri-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs
  • 2-Propanol, 1-(2-butoxy-1-methylethoxy)-
  • Distillates (petroleum), hydrotreated light

A Nalco spokesman claims that “Both COREXIT dispersants have been approved by the EPA as part of the National Contingency Plan for treating oil spills.” What they don’t bother to mention is the circumstances for which they are approved, and that the approved dispersal method does NOT allow for it to be used sub-surface. In fact, as we reported earlier in this ecological disaster, the EPA and BP are specifically prohibited from using it in that fashion by the Clean Water Act of 1972. (CWA) Read more

Why is BP Still Stalling?

For 40 days now, the oceans of the world have been contaminated by the disaster in the Gulf.  The resulting oil spill has spewed tens of millions of gallons of oil into the Gulf, with no end in sight.  Another million gallons of toxic Corexit dispersing solvents have been poured into the waters, both on top and below… and still we witness one hair-brained scheme after another from the “experts” at BP.  Top Hat, Top Kill, talk of stopping it up with golf balls (as if a fluid under pressure wouldn’t find its way through THAT filter?) and never much sense or likelihood of success in any of them.  At this point, one simply must wonder why BP is stalling.
