Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute aquatic toxicity:
96 h, LC50 (Oryzias latipes): 19.4 mg/L (time-weighted average concentration)
48 h, EC50 (Daphnia magna): 3.11 mg/L (time-weighted average concentration)
72 h, ErC50 (Pseudokirchneriella subcapitata): 5.4 mg/L (time-weighted average concentration)
Aquatic chronic toxicity:
72 h, NOEC (Pseudokirchneriella subcapitata): 1.49 mg/L (time-weighted average concentration)
21 d, NOEC (Daphnia magna): 0.59 mg/L (time-weighted concentration)
Biodegradation: not readily biodegradable: 0 % after 28 days (% degradation O2 consumption, OECD 301D)
Partition coefficient: log Kow = 3.01 at 20 °C
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. In all aquatic tests the test item showed toxic effect on the tested species. The determined EC50 for Daphnia magna was 3.11 mg/L and for unicellular green algae was 5.4 mg/L. The NOEC in the algal inhibition study was determined to be 1.49 mg/L. Based on these results, the substance is no classified as short-term (acute) aquatic toxic but is classified as long-term (chronic) aquatic toxic in category 2 (H411) according to Regulation (EC) No 1272/2008 (CLP), as amended for the twelfth time in Commission Regulation (EU) 2019/521.
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.
