PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
An evaluation of the inherent properties of the test substance 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 biodegradability study according to OPPTS 835.3110 (Rivera, 2007) and regarded as a key study (Klimisch score of 1). Under the conditions of the test, the test substance was determined to be readily biodegradable within 28 days. It can therefore be concluded that based on the criteria mentioned above the substance is not persistent in the environment. The substance is concluded to be not P/vP.
The bioaccumulation assessment is based on the screening criteria in Annex XIII of the REACH Regulation.The available evidence on the bioaccumulation potential for the substance indicates that the screening criteria for bioaccumulation potential (B and vB) are not met. Based on a log Pow of -4.5 at neutral pH, a low BCF can be estimated. Since the log Pow of the substance is far below the threshold of 4.5, the screening criteria for bioaccumulation are not fulfilled and the substance is concluded not to have a bioaccumulative potential (not B / not vB).
The available evidence on the toxicity potential for the substance is sufficient for an assessment based on the Annex XIII criteria for this endpoint. Taking into account the available data and the criteria of the CLP regulation (REGULATION (EC) N° 1272/2008), the substance does not fulfill the screening criterium for being considered as T.
Taking into account the conclusions that the substance is not P/vP, not B/vB and not 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.
