Additional information
The most sensitive species is Algae with an EC50 = 40 mg/L. For the other species, the toxicity was above than the limit of solubility.
Conclusion on classification
The substance is readily biodegradable.
The substance has no potential of bioaccumulation .
The acute toxic effects on fish and Daphnia Magna are conclusive but not sufficient for classification due to the fact that no EC50 can be calculated at the limit of solubility of the substance. Effect on Daphnia were observed (EC50 > 32 mg/L).
Classification according to Annex VI of Directive 67/548/EEC: Not classified for the environment
CLP classification according to reglement CE 1272/2008 including ATP2 : Not classified for the environment
GHS classification (GHS UN rev.2, 2007): Not classified for the environment
