Conclusion on classification
As the substance poses no hazard to aquatic organisms, and consequently not to the various environmental compartments (freshwater, marine water, STP, sediment (fresh and marine water), soil, air, predators), no classification is warranted.
Aquatic acute toxicity
96 h LC50 value (Brachydanio rerio): > 108 mg/L (nominal concentration)
48 h, EC50 (Daphnia magna): > 108 mg/L (nominal concentration)
72 h, ErC50 (Raphidocelis subcapitata): > 108 mg/L (nominal concentration)
Aquatic chronic toxicity
72 h NOEC (Raphidocelis subcapitata): 108 mg/L (nominal concentration)
Biodegradation: not readily biodegradable: 1 % based on CO2-evolution after 28 days (% degradation O2 consumption, OECD 301 B)
Partition coefficient: log Kow = -2.2 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 to be not readily biodegradable under the test conditions. In all aquatic tests the test item showed no toxic effect on the tested species. The determined EC50 and NOEC for Daphnia magna and green algae were > 108 mg/L. The LC50 to zebrafish was determined to be > 108 mg/L. Based on these results, the substance is neither to be 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 fifteenth time in 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.
