Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Assessment”.
Persistence
The substance is not readily biodegradable based on screening criteria. This was shown in a study according to EU Method C.4-E (24% biodegradation after 28 d) and a BOD test (24.1% biodegradation after 28 d). Thus, the substance meets the screening criterion for persistency and is considered to be potentially persistent (P) or very persistent (vP) in the environment.
Bioaccumulation
In accordance with ECHA Guidance R.11 (ECHA, 2017) the substance is not considered to meet the screening criterion for bioaccumulation in aquatic species since the log Kow of 2.8 is below the trigger value of 4.5.
Thus, the substance does not meet the screening criterion for bioaccumulation and it is not considered to be bioaccumulative (B) or very bioaccumulative (vB) in the environment.
Toxicity
Long-term aquatic toxicity results are available for aquatic invertebrates and algae. The lowest long term effect value was identified for aquatic invertebrates with a NOEC (21 d) of 3.2 mg/L which is above the trigger value of 0.01 mg/L. The substance is furthermore not classified for carcinogenicity, mutagenicity, reproduction toxicity or specific target organ toxicity according to Regulation (EC) No 1272/2008 (CLP) and all further amendments (ATPs). Thus, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not met and the substance is not considered to meet the T criterion.
In conclusion, the substance is not considered to be PBT or 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.
