Conclusion on classification

Three acute endpoints for three different trophic levels are available. The lowest LC50 is found for fish and is 50.2 mg/L. Three chronic endpoint are available as well, the most sensitive species is Daphnia, with an EC10 of 1.03 mg/L.

The substance is not readily or inherently biodegradable and does not hydrolyse quickly.

The substance has a low log Kow (log kow < 3).

These findings do not lead to classification under Directive (67/548/EEC).

Under Regulation (EU) No 286/2011 (2nd ATP to CLP) based on chronic data, no environmental classification is needed.
