Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 has been based on the available screening criteria. Regarding the persistency assessment, no degradation has been observed under the tested conditions of a ready biodegradation test. The major compartments for partitioning are predicted to be water phase and air. The substance is estimated to show rapid indirect photolysis. Therefore, abiotic degradation may play a significant role and indicates that the substance is not persistent per se. Based on the available information, a definitive conclusion on persistency could not be drawn.
An experimental study to determine the BCF value is not available. Based on the logKow of the test substance, the B-criterion (but not vB) has been considered as potentially fulfilled in a worst-case approach.
The test substance does not fulfil the toxicity criterion. The aquatic toxicity data (acute and chronic studies) reveal effect levels above the trigger value of 0.01 mg/L and the test substance is classified neither as carcinogenic (Cat. 1A or 1B) germ cell mutangeic (Cat. 1A or 1B) or toxic to reproduction (Cat. 1A, 1B or 2) nor with an STOT RE1 or RE2 in accordance to CLP regulation EC No. 1272/2008.
In conclusion, based on the available screening information, the substance is not considered to fulfil the criteria for 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.
