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.
