Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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): 676 mg/L (measured concentration)
72 h, ErC50 (Raphidocelis subcapitata): >100 mg/L (geometric mean measured concentration)
Aquatic chronic toxicity
72 h, ErC10 (Raphidocelis subcapitata): 12.0 mg/L (geometric mean measured concentration)
Biodegradation: readily biodegradable: 81.9 % after 28 days (% degradation ThOD, OECD 301 D)
Partition coefficient: log Kow <0.3 at 25 °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 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 >100 mg/L and the 72h-EC10 of a toxicity to alga and cyanobacteria test with the test substance was determined to be 12.0 mg/L. Based on these results, the substance is neither classified as aquatic acute toxicity nor classified as aquatic chronic according to Regulation (EC) No 1272/2008 (CLP) as amended for the tenth time in Commission Regulation (EU) 2017/776.
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.
