Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): > 0.69 mg/L

72 h, ErC50 (Algae): > 0.76 mg/L (measured)

96 h, LC50 (Fish): > 1 mg/L (nominal)

Aquatic chronic toxicity

21 d, EC10 (Daphnia magna): 0.027 mg/L (calculated)

72 h, NOErC (Algae): 0.76 mg/L (measured)

21 d, NOEC (Fish): > 0.94 mg/L (measured)

Biodegradation: not readily biodegradable: 5 % after 28 days (OECD 301)

Classification according to CLP

Based on the data above, the substance does not have to be classified for acute and chronic toxicity. The above values were obtained by using auxiliary solvents. Thus, the water solubility was extended tremendously. Since all values are in excess of the water solubility no classification is needed according to Regulation (EC) No 1272/2008 (CLP).
