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).

R52/53

UN GHS

Category Acute 3; Category Chronic 3
