Opponents say the dispersants
themselves were toxic, that they may have exacerbated environmental damage, and that they were ineffective at breaking up the already dispersed oil erupting from the wellhead.
are a blend of chemical compounds used to break down oil slicks into smaller drops of oil, making them easily degraded by natural processes or diluted by large volumes of water.
were applied to the surface either through aerial spraying or by vessels within 3 nautical miles (5.
They studied the effect of chemical structure of dispersants
and concluded that the hydrophilic part should have sufficient length to negate the van der Waals forces.
In the meantime, chemical dispersants
, including Corexit 9500A, were used both underwater and on surface to dissipate oil slicks (Kujawinski et al.
ZetaSperse 3800 dispersant
is a clear liquid broad utility dispersant
applicable across all pigment and particle types in resin-free and resin-minimal systems.
(including Specialty Dispersants

Clarke developed an ink using a pigment and a reactive polymer so that the pigment and polymer remain soluble without additional dispersants
are the second largest additive in volume with one-fifth of the tons.
Ionic Polymers: The majority of dispersants
in aqueous dispersions are based on inexpensive anionic polymers.
Baby" corals of at least some species are vulnerable to Deepwater Horizon oil and are especially likely to die when exposed to dispersants
used during a spill, according to a lab-based study by Mote scientists published in the journal PLOS ONE earlier this year.
Pedigo has aggressively challenged the EPA for, as he alleges, "not adhering to the spirit of the very Clean Water Act that the EPA is there to enforce by pre approving toxic Corexit dispersants
