Description of key information

IC50: 100 mg/l

Key value for chemical safety assessment

EC50 for microorganisms:
100 mg/L

Additional information

A complete study and two summaries are available performed according to OECD 209, on the substance under registration resulting in LC50 > 10000 mg/l (highest tested concentration). In the key study, the respiration rate of the activated sludge was not inhibited by the test article and the IC50 was determined to be higher than 100 mg/l.

The conservative value of IC50 greater than 100 mg/l indicated in the key study has been considered as representative for Chemical Safety Assessment.
