Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is no Guideline test on bioaccumulation in terrestrial or aquatic organisms available. Therefore, the bioconcentration factor of the substance was estimated according QSAR models described in the Technical Guidance Document on Risk Assessment (2003). Considering the calculated values for the BCF in earthworm (0.96 L/kg) and in fish (1.41 L/kg) no accumulation in biota is expected. In addition,the constituents of the reaction product (substance) hydrolyse in aqueous media. Thus, experimental determination of the bioconcentration in aqueous media is not possible.Furthermore, direct exposure to the soil compartment does not occur.Therefore, a test on bioconcentration of the substance or its constituents in terrestrial or aquatic organisms is scientifically not justified. The available data are sufficient
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.
