Conclusion on classification

No hazardous effects were detected up to the limit of solubility in the three available acute toxicity studies.

Concerning chronic toxicity, the lowest long-term endpoint value was the 33d-NOEC value obtained in an OECD 210 study with the fathead minnow, equal to 0.25 mg/L (TWA measured concentrations). This endpoint value leads to an Aquatic Chronic 2/H411 classification, considering that the substance is not rapidly degradable.
