Hi gyrocopter,
Thank you for an interesting question.
Dispersants and Bioremediation
http://response.restoration.noaa.gov/faqs/dispers.html
"Q. Can you tell me where I can get some chemical dispersant to use in
my science experiments for school? I need only a small quantity.
A. To our knowledge, commercial dispersants aren't available in stores
and generally aren't available in small quantities. Your best bet
would be to contact dispersant manufacturers directly to ask about
purchasing a small amount. The EPA offers information -
NCP Product Schedule and Notebook
http://www.epa.gov/oilspill/ncp/index.htm
about some of the common dispersants authorized for use on oil
discharges in the U.S., including contact information for their
manufacturers.
A less-expensive alternative would be to use liquid dishwashing
detergent rather than a commercial dispersant in your experiments.
Bird rehabilitators use dishwashing detergent to wash live birds that
are oiled in oil spills, and we often use dishwashing detergent to
demonstrate how dispersants work on oil. Detergent is not exactly the
same as commercial dispersants, but it works in a similar way. Grease
and oil on dishes binds to the detergent, and washes away in the rinse
water. Likewise, dispersant binds to oil on the water surface, so that
the oil can mix and disperse into the water."
