Additional information
Conclusion on classification
Three acute endpoints for three different trophic levels are available. The lowest EC50 is found for Daphnia (31.7 mg/L). Two chronic endpoints are available for algae ( 72h-ErC10 is 81.8 mg/L) and Daphnia (21 d NOEC = 20 mg/L)
The substance is not readily or inherently biodegradable and does not hydrolyse quickly.
The substance has a low log Kow (log kow 1.6).
Based on the above data the following classifications are applicable:
Regulation (EU) No 286/2011
Category chronic 3
Directive (67/548/EEC).
