Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The available measured data for degradation in soil indicate that after 51 days contact time, constituents of GTL Gasoil were not detectable. It was not firmly established whether this is due to biodegradation, loss by evaporation or that the constituents were irreversibly bound to the soil matrix. Scientific judgment would suggest that it is probably a combination of all three. Similarly, studies with full-range GTL Base Oil Distillates and GTL Base Oil 3 indicated a significant degree of test substance removal, most of which can be attributed to biodegradation processes.

Since the constituents of Hydrocarbons, C18-C24, isoalkanes, <2% aromatics are within the carbon number range covered by the read across substances, it can therefore be concluded, based on the available weight of evidence, that a significant degree of removal, including biodegradation, will occur in soil.
