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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the low solubility and complex nature of the test item, media for investigations of short-term aquatic toxicity were prepared as saturated solutions.
Conclusion on classification
Long-term toxicity data are available for three trophic levels (fish, Daphnia and algae) and have been used to calculate appropriate PNECs. However, the species of fish selected together with the method used by the Chinese testing house, plus expert assessment of overall substance-specific aquatic toxicity results leads to the opinion that classification for long-term aquatic toxicity is unnecessary in the EU.
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.
