Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): 60 mg/L (nominal)

72 h, ErC50 (Raphidocelis subcapitata): 56 mg/L (nominal)

Aquatic chronic toxicity

72 h, EC10 (Raphidocelis subcapitata): 30.9 mg/L (nominal)

Biodegradation: The substance is not readily biodegradable but inherently biodegradable (33.8 % after 28 days based on its ThODNH4; OECD 301 D).

Partition coefficient: log Pow 1.59 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 but inherently biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72h EC10 (growth rate) of 30.9 mg/L. The 72h EC50 (growth rate) for algae was determined to be 56 mg/L and the 48-h EC50 for aquatic invertebrates was determined to be 60 mg/L. Based on these results, the substance is not classified for short term (acute) aquatic toxicity, but classified for long term (chronic) aquatic toxicity Category 3 according to Regulation (EC) No 1272/2008 (CLP) as amended for the tenth time in Commission Regulation (EU) 2017/776.
