Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The Substance displays a low ready biodegradability in an OECD closed bottle test. Given the insolubility in water, it was not possible to assess effects of hydrolysis on the substance. Studies on direct phototransformation in water are not available but it is assumed on the basis of chemical structure and nature of use that the substance is not degraded by direct photolysis. In conclusion, the Substance is considered as vP (and P). The Substance has a measured log Pow of 4.3, indicating a potential concern for bioaccumulation. However, a bioaccumulation study performed in carp produced BCF at high exposure level (0.1 ppm) of 15 – 58 and at low level exposure (0.01 ppm) of 61 – 124 indicating that the Substance is not bio-accumulative. In conclusion, the substance is not expected to accumulate significantly in aquatic organisms. The test substance neither fulfils the B nor the vB criterion. The substance is not T. In conclusion, the substance is not PBT/vPvB.
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.
