Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No terrestrial toxicity data are currently available for the registered substance. Soil toxicity studies are not required for Annex VII substances under the REACH Regulation. However, due to the high adsorption potential of the substance, the potential significance of this compartment has been assessed qualitatively.
The registration substance has an extremely low water solubility (5.8E-05 mg/L) and very high log Kow (9.0). These values indicate that the equilibrium between dissolved substance in soil interstitial water and adsorbed substance on soil solids will be significantly in favour of the adsorbed form and assumed to be non-bioavailable. At equilibrium, the solids : water weight ratio is such that exposure via the interstitial water would be very low in absolute terms and also as a fraction of the total applied to soil. The feasibility of studying the parent substance in a standard study is also uncertain.
In case of a tonnage upgrade in future, necessitating a quantitative exposure assessment, the approach for terrestrial ecotoxicity endpoints will be revisited.
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.
