Classification according to CLP

Based on the data compiled above, the substance is not readily biodegradable and has a log Kow ≥ 4.0. The lowest available acute effect concentration (EC50 (48 h)) was < 1 mg/L and was obtained for aquatic invertebrates. The single chronic effect concentration for aquatic algae (ErC10 (72 h)) was also < 0.1 mg/L. Therefore, the substance is classified and labelled as acute 1 and chronic 1 for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
