Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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): 42.7 mg/L (based on nominal concentrations)
72 h, ErC50 (biomass) (Desmodesmus subspicatus): 20.4 mg/L (based on nominal concentrations; recalculated)
Aquatic chronic toxicity
72 h, ErC10 (biomass) (Desmodesmus subspicatus): 6.04 mg/L (based on nominal concentrations; recalculated)
Biodegradation:
The test substance was not readily biodegradable by OECD criteria (0 % biodegradation after 28 days).
Partition coefficient:
Log Pow = 2.8
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
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 toxicity test to algae (Pseudokirchneriella subcapitata). The 72h ErC10 and the ErC50 (biomass) of the test substance was determined to be 6.04 and 20.4 mg/L, respectively (the biomass is considered to be relevant for classification, see IUCLID section 6.1.5). The test substance was found to be not readily biodegradable. The substance has a log Pow of 2.8. Based on these results, the substance is not classified as short term (acute) aquatic toxicity, but classified as long term (chronic) aquatic toxicity Category 3 (H412: Harmful to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP) as amended for the 12th time in Commission Regulation (EU) 2019/521. The substance is labeled with H412: Harmful to aquatic life with long lasting effects.
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.
