Conclusion on classification

The results of the available valid acute aquatic toxicity studies with three species from three trophic levels show that the substance does not need to be classified for acute aquatic toxicity in accordance with CLP Regulation (EC) 1272/2008 and its second amendment Commission Regulation (EU) 286/2011 or with DSD Commission Directive 2001/54/EC adapting for the 28th time Council Directive 67/548/EEC. The EC50 values of the algal and invertebrate acute toxicity tests are in the range from 1 to 10 mg/L. As the substance is rapidly degradable, but has a log Kow of 4.0, the substance needs to be classified for long-term aquatic hazards with Category Chronic 2 (H411) according to CLP and with R51/R53 according to DSD.
