Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Comparison with the Criteria of Annex XIII. An assessment of the PBT/vPvB status of the test substance has been made using all available data.
Persistence Assessment. A modified sturm test (OECD 301B; see Section 5.2.1) showed that the test substance is not readily biodegradable; the test substance is therefore identified as being potentially persistent.
Bioaccumulation Assessment: No studies to assess bioaccumulation in aquatic species have been conducted. The low log kow value (<4.5) indicates that the test material is unlikely to be bioaccumulative in aquatic systems, and is such is considered to have a low potential for bioaccumulation.
Toxicity assessment: The acute toxicity for all three trophic levels are much higher than the PBT screening criterion of < 0.1 mg/L (Daphnia magna the most sensitive species with a 48hr EC50 of 1.7 mg/L).
The overall conclusions, based on the present available data, are that the (screening) criteria for PBT/vPvB, as outlined in Annex XIII of Directive 2006/121/EC, are not met and that further testing in the scope of the final PBT assessment is not considered to be required.
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.
