Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
All calculations of PNECs were based on the standard approach as described in the REACH guidance with the water solubility as starting point for the PNECaqua. This approach is considered to represent a worst case, as an alternative approach based on the NOEC in daphnia of 0.08 mg/L (Environment Japan, 1998, Klimisch 4) with an assessment factor of 100 would lead to a PNEC of 0.8 ug/L (slightly above the value used for risk assessment).
Conclusion on classification
No classification for environmental toxicity is considered necessary
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.
