Description of key information

The 3-h EC50 value is>1000 mg/L in microorganisms. 

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

The toxicity towards microorganisms was determined in a respiration inhibition test performed according to OECD guideline 209 and in accordance with GLP criteria. As the test substance was sparingly soluble in water, water accommodated fractions were prepared using loading rates of 0, 1, 10, 100 and 1000 mg test substance/mL. Test concentrations were not analytically confirmed. In this 3 -h study, a maximum inhibition of 24% was observed at the highest concentration tested. Based on these findings, the EC50 is determined at >1000 mg/L.
