Additional information
Conclusion on classification
Acute aquatic toxicity
Daphnia were the most sensitive species in acute aquatic toxicity tests according to OECD guideline 202, resulting in a 48 -hour EC50 of 2.52 mg/L. Based on acute aquatic toxicity results obtained, the test substance was not classified and labeled for acute aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the seventh time in Regulation EC 605/2014 and to Directive 67/548/EC (DSD), as amended for the 31st time in Directive 2009/2/EG.
Chronic toxicity
Lemna gibba was used in a growth inhibition test, according to OECD guideline 221. Based on the frond number, the 7 -d EC50 was 66.414 mg/L, the 7 -d EC10 was 0.046 mg/L. The test substance was not readily biodegradable. The required pass level for ready biodegradability within a ten days window was not reached. Based on the EC10 value, the test substance has to be classified and labeled as environmental chronic toxic cat. 1 (M-factor 1), H410 according to Regulation (EC) No 1272/2008 (CLP), as amended for the seventh time in Regulation EC 605/2014 and with N; R51/53 according to Directive 67/548/EEC (DSD), as amended for the 31st time in Directive 2009/2/EG
