EC50 (48 h) in aquatic invertebrates (Daphnia magna) > 100 mg/l.

NOEC (7 d) in aquatic plants (lemna) for frond number and dry weight both growth rate and yield = 100 mg/l

EC50 (3h) in microorganisms > 1000 mg/l.

Additional information

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h) for fish, EC50 (48 h) for daphnia and EC50 (72 - 96 h) for algae.

In available studies, no indication of toxicity of the substance was seen.

Based on results with fish, daphnia and aquatic plants, no classification for acute aquatic toxicity was applied. 

No chronic toxicity data is available from long-term studies. In case of lack of chronic data, the potential for chronic toxicity is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification is 100 mg/l.

Based on available results, no classification for chronic or acute aquatic toxicity was applied according to the CLP Regulation (EC 1272/2008).
