Description of key information

The toxicity to micro-organisms was not assessed in a seperate test. Instead the results obtained for the toxicity control in the ready biodegradation study were used. The test item was found to have no inhibitory effects to the activated sludge at a concentration of 30.3 mg/L. The NOEC value can hence be set at 30.3 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
30.3 mg/L
