Conclusion on classification

Three acute endpoints for three different trophic levels are available. The lowest EC50 is found for Daphnia and is 51.9 mg/L. Two chronic endpoint for Daphnia, the most sensitive species, and algae are available, the 21d-NOEC on reproduction is 2.58 mg/L.

The substance is not readily biodegradable, but has a low log Kow (log kow < 3), which would lead to R53, but this can be declassified by the chronic NOEC values which are all greater than 1 mg/L.

These findings lead only to R52 for environment under Directive (67/548/EEC), which indicates that the substance is not classified.

Under Regulation (EU) No 286/2011 (2nd ATP to CLP) neither acute nor chronic (based on chronic data of the most sensitive species) environmental classification is needed.
