Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
There are no reliable toxicity data for terrestrial organisms relating to FX511. A waiver is applied for this endpoint as the substance has low potential for adsorption to soil and low exposure potential as the substance is readily biodegradable.
In accordance with REACH Regulation 1907/2006, Annex X, Column 2, studies of the effects on soil organisms need not be conducted if exposure assessment indicates no concern for exposure to environmental compartments. Testing is waived as potential for exposure is low as the 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 terrestrial 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. Additionally, the partition coefficient of FX511 was determined in a reliable study (Walker 2012) where the measured log Kow is 2.98. Therefore, FX511 is considered to have low potential for absorption to soil and sediment. Based on the readily biodegradability of and low absorption potential of the test substance, exposure to terrestrial organisms is unlikely. Also, direct and indirect exposure is unlikely as the substance is not directly applied to soil. No significant exposure of the terrestrial compartment is therefore expected and additional information on the effects of the substance and its degradation products on terrestrial organisms are therefore not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
