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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
The environmental classification was as follows justified: The criteria for classification for hazards to the aquatic environment according to regulation (EC) No 1272/2008 are fulfilled.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008:
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance is not readily biodegradable under the test conditions. The EC50 values based on short-term toxicity data with fish and Daphnia and toxicity data with algae were in a similar range between 1.7 and 8.3 mg/L. The most sensitive endpoint was the short-term toxicity to fish with a 96h-LC50 of 1.73 mg/L.
The EC10 values based on long-term toxicity data with invertebrates and toxicity data with algae were 0.196 - 3.93 mg/L. The most sensitive endpoint was the long-term toxicity to Daphnia with an EC10 of 0.196 mg/L after 21 days.
Based on these results, the substance is classified as chronic category 2 according to Regulation (EC) No. 1272/2008 (H411: Toxic to aquatic life with long‐lasting effects).
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.
