Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence Assessment
The substance is considered as potentially P and vP. Aerobic and anaerobic simulation tests in water/sediment systems and natural soils were performed. The substance was not readily degraded under anaerobic and aerobic conditions. The major pathway of dissipation was adsorption to the sediment and soil by forming non-extractable residues. The calculated DT50 range for entire water/sediment systems was 127 - 1928 days in the aerobic tests and 178 days under anaerobic conditions (recalculated to 12°C). A mineralisation rate of less than 1% was determined in the aerobic test. The DT50 in soil was 6.5 days at 12°C with a mineralisation rate of 22.6% after 119 days at aerobic conditions.
Bioaccumulation Assessment
The substance has a log Pow of -1.362 at pH7 and 23 °C which is below the trigger of 4.5. Thus, the substance does not meet the screening criterion and is not B/vB.
Toxicity Assessment
The substance is classified as STOT Rep. Exp. 2 (H373) according to Regulation (EC) No 1272/2008. Thus, it meets the criteria in Annex XIII of Regulation (EC) No 1907/2006 and is considered to be toxic (T).
In conclusion, the substance is not PBT/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.
