Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): >120 mg/L (measured concentration)

72 h, ErC50 (Desmodesmus subspicatus): 58 mg/L (geometric mean measured concentration)

Aquatic chronic toxicity

72 h, ErC10 (Desmodesmus subspicatus): 23.1 mg/L (geometric mean measured concentration)

Biodegradation: readily biodegradable: 95 - 98 % after 28 days (% degradation CO2 Evolution, OECD 301 B)

Partition coefficient: log Kow <0.3 at 23 °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 readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72h-EC50 of 58 mg/L and the 72h-EC10 of 23.1 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 tenth time in Commission Regulation (EU) 2017/776.
