Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 introduced in appropriate low concentrations.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 220 mg/L
Additional information
As key study on bacterial toxicity a test similar to OECD guideline 209 using domestic activatd sludge as inoculum was identified (BASF 1989). After 30 minutes of exposure an EC20 of 220 mg/L was estimated. This value will be used for further assessment using assessment factors of an EC50 of an similar test due to product safety reasons. In a second test according to Robra on Pseudomonas putida an EC10 of 4010 mg/L after 17 hours of exposure was measured (BASF 1989).
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.
