Conclusion on classification

Acute aquatic toxicity:

96 h, LC50 (Danio rerio): >100 mg/L (nominal concentration)

48 h, EC50 (Daphnia magna): >100 mg/L (nominal concentration)

72 h, ErC50 (Desmodesmus subspicatus): >100 mg/L (nominal concentration)

Aquatic chronic toxicity:

14 d / 28 d, NOEC (Cyprinus carpio): >0.02 mg/L (initial measured concentration)

72 h, ErC10 (Desmodesmus subspicatus): >100 mg/L (nominal concentration)

21 d, NOEC (Daphnia magna): > 100 mg/L (nominal concentration; structural analogue)

Biodegradation: not readily biodegradable: 0 % after 28 days (% degradation O2 consumption, OECD 301F)

Partition coefficient: log Kow > 6.5 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 biodegradable under the test conditions. In all aquatic tests the test item showed no toxic effect on the tested species. The determined L(E)C50 values in the short-term toxicity tests with fish, Daphnia magna and green algae were determined to be >100 mg/L. The long-term NOEC to common carp fish was determined to be > 0.2 mg/L and thus clearly exceeded the limit of water solubility. The ErC10 value was determined to be > 100 mg/L for green algae. 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 twelfth time in Regulation (EU) 2019/521.
