Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 to biological treatment plants in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
In A GLP guideline study according OECD 209 (BASF SE 2016) the inhibition of oxygen consumption has been measured. After 3 h of exposure up to 1000 mg/kg no effects on the respiration rate have been measured. Therefore, the EC10, EC20, EC50 and EC80 were determined to be > 1000 mg/L.
Additionally, the toxicity to microorganisms has been determined according DIN 38412 part 27 using Pseudomonas putida. After 30 min exposure the oxygen consumption has been measured. The EC10, EC50 and EC90 was determined to be above 10000 mg/L.
Therefore, the inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants 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.
