Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic acute toxicity
48 h, EC50 (Daphnia magna): 16.595 mg/L (nominal concentration)
72 h, ErC50 (Pseudokirchneriella subcapitata): 0.732 mg/L (nominal concentration)
Aquatic chronic toxicity
72 h, ErC10 (Pseudokirchneriella subcapitata): 0.237 mg/L (nominal concentration)
Biodegradation: not readily biodegradable: 8.4 % after 28 days (%degradation O2 consumption, OECD 301 D)
Partition coefficient: log Kow = 2.53, 3.38 and 3.66 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 not to be readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72h-EC50 of 0.732 mg/L and the 72h-EC10 of a toxicity to alga and cyanobacteria test with the test substance was determined to be 0.237 mg/L. Based on these results, the substance is classified as short-term (acute) aquatic toxicity Category 1 (H400) and is classified as long-term (chronic) aquatic toxicity Category 1 (H410) according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
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.
