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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One GLP study report is available, which reports bioaccumulation factors (BCF) as 1470, 1736 and 2427 (C14, C16 and C18 congeners respectively) for fish exposed to food containing test material. The corresponding bioaccumulation factor for fish exposed to feed containing the control substance, hexachlorobenzene, was a factor of 10 higher at 23442.
Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment states that a value > 2000 is indicative of a PBT substance. One of the three chain lengths is slightly greater than this value, however, it is considered unlikely that the C18 fraction responsible for the experimentally derived BCF value would ever be present in sufficient concentration to cause this effect in normal environmental conditions: this congener is one of the lower concentrations present in the material, and also is normally present as part of a complex mixture which is unlikely to separate and exhibit these different BCF potentials. The material as Registered is therefore not considered to demonstrate bioaccumulation potential.
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.
