Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 inhibition of the degradation activity of activated sludge is not anticipated when the substance introduced in appropriate low concentrations. The EC10 and EC50 values above 1000 mg/L were determined after 180 minutes of incubation.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
In a test with domestic activated sludge the inhibition of oxygen consumption was examined according to OECD guideline 209. Bacteria were exposed for three hours to the test substance at concentrations of 62.5, 125, 250, 50, 1000 mg/L. No inhibition of respirometric activity in any of the tested concentrations was detected. Thus the determined EC50 and EC10 values were > 1000 mg/L.
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.
