Description of key information

Key value for chemical safety assessment

EC50 for microorganisms:
2.37 mg/L

Additional information

As no data is available on the reaction mass of m-Cresol and p-Cresol, the assessment is based on data available on individual constituents. The most severe toxicity value was obtained with microorganisms exposed for 30 minutes to p-Cresol: 30min-EC50 = 2.37 mg/L. As a worst-case, this value is assigned to the reaction mass for the assessment.
