PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is considered to fulfil the P and might fulfil the vP criterion and B criterion as it was observed to be "not readily biodegradable" under the test conditions (0% biodegradation within 28 days) and has a mean log Kow of 5.3 (measured values 5.0 to 5.6). There is evidence that the substance might not be very bioaccumulative. The molecular weight of the substance is 886.17 g/mol and the branched structure is estimated to be larger than 1.7 nm. According to the Guidance on information requirements and chemical safety assessment, Version 1.1 November 2012, Chapter R.11, page 29 a molecular weight higher than 700 g/Mol and an average maximum diameter >1.7 nm are indicators that the BCF is below 5000 L/kg. Furthermore the T criterion is not fulfilled thus the substance is considered to be neither PBT nor 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.
