Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge is not expected.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 230 mg/L
- EC10 or NOEC for microorganisms:
- 40 mg/L
Additional information
One activated sludge respiration inhibition test according to OECD guideline 209 (Janssen, 1989) is available for the test substance.
The 3-h EC50 is 230 mg/L and the EC10 is 40 mg/L. Additionally several biodegradation studies exhibit the readily biodegradability of the test substance.
Therefore, depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge is not anticipated.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.
