Description of key information

Paraffin oils, sulfochlorinated, saponified was tested for toxicity towards microorganisms according to OECD-Test Guideline 209: "Activated Slugde, Respiration Inhibition Test". From the data obtained the respiration rate of activated sludge was inhibited beginning at concentrations of 100 mg/L (4.4 % inhibition). EC50 was calculated to be 810 mg/L within 3 hours (Leuna AG, 1991).

Key value for chemical safety assessment

EC50 for microorganisms:
810 mg/L
