Additional information
Conclusion on classification
The available environmental data (the substance is readily biodegradable, adequate chronic study for three trophic levels and the 21 d NOEC in Daphnia being 0.07 mg/L) suggest that the test substance is hazardous to the aquatic environment, warranting classification as Aquatic Chronic 2 - H411 (Toxic to aquatic life with long lasting effects) according to CLP criteria (EC 1272/2008).
