Ecotoxicological Summary

Conclusion on classification

Aquatic acute toxicity

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

48 h, EC50 (Daphnia magna): >100 mg/L (nominal concentration, exceeded the water solubility of 2.64e-6 mg/L)

Read-across: 72 h, ErC50 (Desmodesmus subspicatus): >100 mg/L (nominal concentration, exceeded the water solubility of 0.00022 mg/L)

Aquatic chronic toxicity

Read-across: 72 h, ErC10 (Desmodesmus subspicatus): >100 mg/L (nominal concentration, exceeded the water solubility of 0.00022 mg/L)

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

Partition coefficient: log Kow = >6.5 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 not be readily biodegradable under the test conditions. In all aquatic toxicity test no effects were observed up to the water solubility of saturation level (nominal concentration of 100 mg/L). Based on these results, the substance is neither classified as short-term (acute) aquatic toxicity nor classified as long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the twelfth time in Commission Regulation (EU) 2019/521.
