Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on Log Pow the partition coefficient of the substance te BCF is considered to be <0.36 - 274.28 L/Kg.
A partition coefficient in excess of 4.5 is considered to be of concern as potential for bioaccumulation, according to screening criteria for bioaccummulation in ECHA guidance (Chapter R.11 PBT Assessment).
The likely reliability of the log Pow is, however, considered to diminish above a value of 6, as noted in Appendix R.11-1 Annex 1 of ECHA guidance on PBT Assessment. Substances with log Pow between 4.5 and 6 are considered likely to be highly accumulating; however no substantial bioconcentration is assumed for compounds having log Pow with values less than 4.5 or greater than 6. For compounds having log Pow greater than 6, a gradual decrease of the BCF is observed and it has been hypothesised within the published literature that a high log Pow is more an effect of solubility than a tendency of the substance to be lipophilic.
This is further supported by the estimation based on the linear correlation used from ECHA technical guidance: Chapter R.7c: Endpoint specific guidance [Veith, G.D., et al. (1979)]the highest BCF is 274.28, considerably below the threshold of concern derived by the REACH criteria of 2000 (B) and 5000 (vB).
Furthermore, controls required for the use of the material are designed ensure no exposure of the substance to the aquatic environment removing any opportunity for bioaccumulation.
It is therefore considered that the substance is considered to not have the potential to bioaccumulate and it is therefore not scientifically justified to undertake a study in fish.
Additional information
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.
