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

Waiver. In accordance with Column 2 of REACH Annex IX, the soil simulation test (required in Section, 9.2.1) does not need to be conducted as direct or indirect exposure of soil is unlikely or if the substance is readily biodegradable. Exposure potential is expected to be unlikely as substance is readily biodegradable. In the environment, ready biodegradability means it can be assumed that FX511 will be biodegraded within the STP process and as a consequence a transfer to the aquatic compartment via STP effluent is not expected. Furthermore, for substances not passing the STP-process but being readily biodegradable, it can be assumed that they will be also biologically degraded in the surface water within a short time. Also, the substance’s low log octanol-water partition coefficient (Log Kow) of 2.98 at a neutral pH indicating low adsorptive potential. Therefore, no additional degradation testing is necessary.
