COREXIT Ingredients

Several weeks ago, Nalco responded to US EPA requests by providing the agency with detailed formulation and ingredient information on our COREXIT dispersants. We further agreed that this information could be shared with any other federal agency and with third party laboratories EPA has been using for its Gulf monitoring and assessment program to allow them to monitor any potential for risks to the environment or public health.

The table below outlines the same ingredient list for our COREXIT dispersants as provided to the EPA.

CAS #	Name	Common Day-to-Day Use Examples
1338-43-8	Sorbitan, mono-(9Z)-9-octadecenoate	Skin cream, body shampoo, emulsifier in juice
9005-65-6	Sorbitan, mono-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs.	Baby bath, mouth wash, face lotion, emulsifier in food
9005-70-3	Sorbitan, tri-(9Z)-9-octadecenoate, poly(oxy-1,2-ethanediyl) derivs	Body/Face lotion, tanning lotions
577-11-7	* Butanedioic acid, 2-sulfo-, 1,4-bis(2-ethylhexyl) ester, sodium salt (1:1)	Wetting agent in cosmetic products, gelatin, beverages
29911-28-2	Propanol, 1-(2-butoxy-1-methylethoxy)	Household cleaning products
64742-47-8	Distillates (petroleum), hydrotreated light	Air freshener, cleaner
111-76-2	** Ethanol, 2-butoxy	Cleaners

* Contains 2-Propanediol

** This chemical component (Ethanol, 2-butoxy-) is NOT included in the composition of COREXIT 9500

COREXIT 9500 is the sole product we have been making for Gulf responders since the spill began. Limited quantities of COREXIT 9527 may have been drawn from existing dispersant stockpiles from around the world. COREXIT 9500 does not include the ingredient 2-butoxy ethanol, an ingredient in COREXIT 9527.

Both COREXIT dispersants have been approved by the EPA as part of the National Contingency Plan for treating oil spills.

In addition, a May 2010 report by the Centers for Disease Control concluded that “because of the strict guidelines that must be followed to utilize dispersants, it is unlikely that the general public will be exposed (directly) to (the) product.” The report further states that “ingredients are not considered to cause chemical sensitization; the dispersants contain proven, biodegradable and low toxicity surfactants.”
