Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 PBT Assessment for the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT/ vPvB assessment (ECHA, 2014).
Persistence Assessment
The substance is neither readily nor inherently biodegradable in standard tests for biodegradability. Thus, the test substance meets the screening criterion for persistency.
Bioaccumulation Assessment
Due to the very low log Kow (<0), the substance has no potential for bioaccumulation. The log Kow of the substance is very much lower than the threshold value of the screening criterion for B (log Kow>4.5). Therefore, the B-criterion is not fulfilled and the substance is neither B nor vB.
Toxicity Assessment
The substance is not toxic to mammals based on the available data. The substance is not classified for the environmental toxicity considering all available acute and chronic toxicity studies of all three trophic levels. It is not classified for carcinogenicity, mutagenicity, reproductive or developmental toxicity. In this case, the substance does not meet the criteria for toxicity and is not considered to be T.
The substance is considered as persistent, but it is not considered as PBT as it does not meet the other two criteria (B, T).
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.
