Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The toxicity to microorganisms was tested in a GLP approach according to OECD guideline 209 using domestic non-adapted activated sludge as inoculum (BASF SE 08G0642/12G231, 2013). After an incubation period of 180 minutes the EC10 was found to exceed 1000 mg/L based on the nominal concentrations. In a study according to DIN 38412, part 8, the EC10 value of the test item on Pseudomonas putida was determined to exceed the highest test concentration of 1000 mg/L (BASF AG 9/1215/88.1988). Hence, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
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.
