Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.

Dispersants are said to facilitate the digestion of the oil by microbes but conflicting results have been reported on this in the context of the Deepwater Horizon oil spill. [161] Mixing dispersants with oil at the wellhead would keep some oil below the surface and, in theory, allow microbes to digest the oil before it reached the surface.

Oil slicks on Lake Maracaibo Volunteers cleaning up the aftermath of the Prestige oil spill. Dispersants can be used to dissipate oil slicks. [54] A dispersant is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping.
The BP (BP) oil spill may be over, but controversy over the company's use of toxic oil dispersants in the Gulf of Mexico is still going strong. Although BP allegedly stopped using the chemicals ...
