Additional information

Conclusion on classification

The lowest acute aquatic toxicity value determined from thre trophic levels tested (fish, daphnia, and algae) was found being an LC50 for fish of 15.0 mg/L. Thus, the substance is not subject to classification for acute aquatic toxicity according to CLP (Regulation EC No. 1272/2008). Furthermore, the organic moiety of the substance was found being readily biodegradable, and the lowest NOEC of three trophic levels tested was for fish, being 5.1 mg/L. Accordingly, the substance is also not subject to classification for chronic aquatic toxicity according to CLP.
