Abstract
The present disclosure relates to an oil dispersant composition for dispersing a crude oil or a petrochemical spill comprising at least 20% (w/w) of a gum comprising a mannosylerythritol lipids mixture; at least 10% (w/w) polyethylene glycol sorbitan ester; and at least 20% (w/w) of a hydrophobic organic solvent, wherein said organic solvent has a flash point superior to the crude oil or the petrochemical spill flash point, preferably superior to 60° C. The disclosure also relates to a method for obtaining said composition as well as a method for dispersing an oil spill, comprising the step of applying the disclosed oil dispersant composition with an oil present in a body of water.
