TotalEnergies FINASOL - Marine dispersants

FINASOL OSR is a range of «third-generation» concentrate marine dispersants. They are considered to be among the best on the market, offering very good eco-toxicological performance.

They can be used pure or diluted at 10% in seawater (references of the profession: MMO type II and III).

FINASOL OSR 52: Offering outstanding performance, Finasol OSR52 provides a rapid and effective response. It is also the benchmark product in the market as being the first product to comply with all three major international regulations – EPA* (USA), MMO** (UK), and CEDRE*** (France). Moreover, Finasol OSR 52 is registered in a great many countries around the world.

FINASOL OSR 51: Finasol OSR 51 is compliant with the MMO (UK) and CEDRE (France) international regulations.

The very specific active ingredients of Finasol® OSR offer high dispersion potential, as shown by the successful registration tests on a variety of crude oils.

In case of oil spill at sea, the appropriate response is always decided by local authorities. They must select the best method to limit the impact while taking into account the NEBA (Net Environmental Benefit Analysis), including geographical area, weather and environmental conditions. Possible responses include mechanical recovery, in-situ burning, or the use of marine dispersants. The later help drive off the oil slick, protecting vulnerable bird habitats and wildlife species on the coast line. They break down hydrocarbon pollutants into microscopic droplets, thus allowing a faster biodegradation process.

Environmental impact evaluation is part of national authorities’ registration processes and includes biodegradability and eco-toxicity tests on marine eco-systems. These criteria, along with TotalEnergies' sustainable development policy, have been key drivers in the selection of solvents and surfactants for the development of Finasol® OSR.
