Additional information
Conclusion on classification
Acute toxicity data (EC50/LC50) for all three trophic levels are >1 mg/L and the substance is readily biodegradable. The lowest chronic toxicity data is from a 21 d Daphnia reproduction study (21 d NOEC = 0.16 mg/L). Therefore, in accordance with the EU CLP regulation (EC) 1272/2008, the substance warrants a classification as Aquatic Chronic 3 - H412 (Harmful to aquatic life with long-lasting effects).
