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.
Chemical dispersants are used in oil spills to mitigate the effects of the spill and promote the degradation of oil particles. The dispersants effectively isolate pools on oil sitting on the surface of the water into smaller droplets that disperse into the water, which lowers the overall concentration of oil in the water to prevent any further ...
