Abstract

A method and process for preventing the penetration and/or adhesion of hydrocarbons such as crude oil or mineral oil-hydrocarbons into or respectively on objects. The natural and/or constructed objects are sprayed with an aqueous solution and/or dispersion of glycolipids resulting in a thin layer covering the object. A hydrocarbon composition can contact the sprayed object and the resulting hydrocarbon; containing mass can be removed with a pressurized water jet. Various ways exist for degrading or separating the hydrocarbons from the run-off. Preferably the aqueous solution and/or dispersion is treated with ultrasonics before being applied to the surfaces of the objects.
