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.
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).
