Additional information

Conclusion on classification

Water solubilty: 0.2g/L

Log Pow: 1.58

Acute fish: LC50 ca 37 mg/L

Acute Daphnia: 37 mg/L

Algae: LC50 2.2 mg/L;  EC10 1.2 mg/L

Chronic fish: NOEC 2.8 mg/L

Acute Daphnia: 37 mg/L

Chronic Daphnia: 11.92 mg/L

Algae: LC50 2.2 mg/L;  EC10 1.2 mg/L

Biodegradation: not readily biodegradable

Acute toxicity

LC/EC50 values are all greater than 1 mg/L therefore, according to Table 4.1.0(a) of the CLP regulation, the substance is not classified for acute (short-term) aquatic hazard.

Chronic toxicity

Adequate chronic data is available for all three tropic levels, is not readily biodegradable. Therefore classification acording to CLP Table 4.1.0(b)(i).  NOECs all greater than 1 mg/L, thus Not classified
