Additional information
Conclusion on classification
The classification of the substance was evaluated based on available experimental data on the three trophic levels:
Fish: LC50 (96h) > 100 mg/l
Daphnia: EC50 (48 h) > 100 mg/l
Algae: ErC50 (72 h) > 100 mg/l
The substance is readily biodegradable, is very water soluble, has a LogPow < 4 and is not expected to bioaccumulate. Based on the acute toxicity results and the ready-biodegradability, the substance is not classified for aquatic toxicity as per the CLP Regulation EC No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
