Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): 0.294 mg/L (geometric mean measured concentration)
72 h, ErC50 (Pseudokirchneriella subcapitata): > 1.41 mg/L (geometric mean measured concentration)
Aquatic chronic toxicity
72 h, EC10 (Pseudokirchneriella subcapitata): 0.785 mg/L (geometric mean measured concentration)
Biodegradation: not readily biodegradable: 9 % after 28 days (% degradation O2 consumption, EU Guideline C.4-E)
Partition coefficient: log Kow = 6.44 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 not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the acute toxicity test to daphnia which revealed a 48h-EC50 of 0.294 mg/L. The test on toxicity to algae and cyanobacteria revealed a 72-hour EC10 of 0.785 mg/L. Based on these results, the substance is to be classified as short-term (acute) aquatic toxicity category 1 with an M-factor = 1 and has to be classified as long-term (chronic) aquatic toxicity category 1 with an M-factor = 1 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.
