The very specific active ingredients of FINASOL® OSR offer a high dispersion potential, as indicated by successful tests on a variety of crude oils.

In case of an oil spill at sea, the appropriate response is always decided by the local authorities. It is up to them to select the best method to limit the impact while taking into account the NEBA (Net Environmental Benefit Analysis), including geographic area, time, environmental conditions.

Possible responses include mechanical recovery, in-situ burning, and the use of marine dispersants. The latter help protect the habitats of vulnerable bird species and wildlife located on the coast by preventing oil from reaching the shoreline. The mode of action is the decomposition of oil into microscopic droplets, allowing for a more rapid biodegradation process in the marine environment.

Environmental impact assessment is part of the registration process of national authorities and includes biodegradability and ecotoxicity tests on marine ecosystems. These criteria, together with TotalEnergies Fluids' sustainable development policy, were key factors in the selection of solvents and surfactants for the development of the OSR range.
