Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
An evaluation of the inherent properties of T001333 is performed against the ANNEX XIII criteria. If insufficient data were available, the screening criteria as laid down in ECHA Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment (2014) were applied. The persistency assessment is based on the screening criteria in Annex XIII of the REACH Regulation. The biodegradation potential of the test substance has been assessed in a OECD 301F study ( Grutzner, 2003). The results reveal that the test substance does not degrade (ca. 0% observed under the conditions of the test) and the substance is hence considered to be not readily biodegradable. It can therefore be concluded that based on the criteria mentioned above the substance is persistent in the environment. The substance is concluded to be P/vP.
The bioaccumulation assessment is based on the screening criteria in Annex XIII of the REACH Regulation. A measured Log Kow of 1.7 have been determined in an OECD 107 study ( Tognucci, 2003). Since the measured log Kow of the parent compound is below the criterium of log Kow < 4.5 no further assessment on bioaccumulation is needed. The test substance is concluded to be not B/vB.
The toxicity assessment is based on the screening criteria in Annex XIII of the REACH Regulation. The test substance is classified as toxic for reproduction category 2 and toxic for STOT RE category 2. The test substance hence is considered to be Toxic.
In conclusion, taking into account that the substance is P/vP, not B/vB and T, the substance should not be considered as a PBT/vPvB substance.
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.
