Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): 706 µg/L (time weighted average test concentration)
72 h, ErC50 (Pseudokirchneriella subcapitata): > 249 µg/L (geometric mean measured test concentration)
Aquatic chronic toxicity
72 h, ErC10 (Pseudokirchneriella subcapitata): > 249 µg/L (geometric mean measured test concentration)
72 h, NOEC (Pseudokirchneriella subcapitata): 18.6 µg/L (geometric mean measured test concentration)
Biodegradation: not readily biodegradable: 29 % after 28-days (Manometric Respirometry Test, OECD 301 F)
Classification according to CLP
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the acute toxicity test to Daphnia magna which revealed a 48 h EC50 of 706 µg/L. The algal growth inhibition test with Pseudokirchneriella subcapitata revealed a 72 h NOEC of 18.6 µg/L. Based on these results, the substance is to be classified for short-term (acute) aquatic toxicity (Aquatic Acute 1, M-Factor: 1) and for long-term (chronic) aquatic toxicity (Aquatic Chronic 1, M-Factor: 1) according to Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849.
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.
