Additional information

The values derived as PNECs above are fully in line with observed results for aquatic toxicity as this substance shows only effects, if at all, to aquatic organisms way above all thresholds for classification & labelling (100 mg/l) for some species even orders of magnitudes above. In addition the substance is readily biodegradable as shown in the data sections and a hazard to aquatic organisms is not expected.

Conclusion on classification

Based on available data substance is neither classifiable for acute nor chronic aquatic toxicity according to CLP (EC No 1272/2008)
