Description of key information

The test was performed according to EU Method C.3 (Algal Inhibition Test).
The study was performed without the analytical determination of the test substance concentrations. Because the test substance is multi-component poorly soluble substance the water-accommodated fractions (WAFs) were prepared for preliminary and full test.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
100 mg/L

Additional information

As the test substance was tested by using the water-accommodated fractions (WAFs) and nominal concentrations (loading rates) were used, EL (resp. NOELR) parameters were used instead of EC (resp. NOEC) values.

EL50 (72 h) > 100 mg/l.

NOELR (72 h) = 100 mg/l.
