Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Persistence
The substance is neither readily biodegradable nor inherently biodegradable and does not undergo hydrolysis in aquatic media, hence it can not clearly be stated whether the substance might not be persistent.
Bioaccumulation
A test on bioconcentration in aquatic organisms is not needed due to the very low potential of the test substance for bioaccumulation indicated by a low logKow (logKow = -1.3, experimental result at pH 9.3). Therefore, the substance is presumably not a "B" substance.
Toxicity
Based on the results obtained from the acute aquatic toxicity studies including sediment, the substance is presumably not a “T” substance because EC/LC50 are clearly above 0.1 mg/l (according to the screening criteria laid down in the Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment).
Further, the substance is not classified as CMR according to Directive 67/548/ EEC (DSD) nor as CMR according to Regulation EC No 1272/2008 (CLP-Regulation) and the substance does not exhibit any othere evidence of chronic toxicity, as identified by the classifications T, R48 or Xn according to Directive 67/548/ EEC (DSD) or specif target organ toxicity after repeated exposure (STOT RE Cat. 1 or 2) according to Regulation EC No 1272/2008 (CLP-Regulation).
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.
