Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The toxicity of the test substance to microorganisms was determined as part of a toxicity control in a OECD TG 301D guideline study in compliance with GLP criteria. Secondary activated sludge (obtained from a wastewater treatment plant treating predominantly domestic wastewater) was exposed to 6.7 mg/L sodium acetate (positive control) with and without addition of 2 mg/L of the test substance. The oxygen depletion in both solutions was measured and compared. Inhibition of the degradation of sodium acetate by the addition of the test substance did not occur. Moreover, inhibition of the endogenous respiration of the inoculum by the test substance was also not detected. Based on the findings, the NOEC for microorganism toxicity was determined to be 2 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 2 mg/L
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
