Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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): 41.1 mg/L (nominal concentration)
72 h, ErC50 (Pseudokirchneriella subcapitata): 37.93 mg/L (nominal concentration)
Aquatic chronic toxicity
72 h, ErC10 (Pseudokirchneriella subcapitata): 7.12 mg/L (nominal concentration)
Biodegradation: readily biodegradable: 94 % after the 10-day window days (% degradation O2 consumption, OECD 301 D)
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 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 37.93 mg/L and the 72h-EC10 of a toxicity to alga and cyanobacteria test with the test substance was determined to be 7.12 mg/L. Based on these results, the substance is neither classified for short-term (acute) aquatic toxicity nor classified for long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fourteenth time in Commission Regulation (EU) 2020/217.
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.
