Conclusion on classification

The substance was tested for three trophic levels in the aquatic enviroment using acute test design and the most sensitive species was Daphnia magna showing an EC10 = 10.58 mg/L. The substance is readily biodegradable. Based on the available data, the substance is not classified for environment according to Annex VI.
