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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Log Kow was determined using the HPLC method (OECD 117 and EU Method A.8) and found to be in the range < 1.0 to > 6.5. The substance is not expected to bioaccumulate because, in accordance with ECHA Guidance on information requirements and chemical safety assessment Chapter R11: PBT/ vPvB assessment (Version 3.0; June 2017), organiccomponents with Log Pow < 4.5 are not expected to meet the B criterion (BCF value of 2000 based on wet weight of the organism, which refers to fish in most cases) and, for components with determined Log Pow > 6.5, bioaccumulation is not expected because a decreasing relationship exists between BCF and Log Kow at high Log Kow (> 6).
Key value for chemical safety assessment
- BCF (aquatic species):
- 2 000 dimensionless
Additional information
Worst case BCF value added for purposes of risk assessment to permit calculation of predicted effect conentrations by Chesar 3.
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.
