Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
A GLP-guideline study was conducted according OECD guideline 209 (Huntingdon Research Centre Ltd. 1993m). Due to the low solubility of the test substance a limit test was conducted using 1 mg/L test substance (nominal) and Tween 80 as an emulsifier. 1.0 mg/L was the highest test concentration that could be prepared due to the limited solubility of the test substance in water.
After 3 h contact time the EC50 (respiration inhibition) was determined to be > 1 mg/L.
Therefore, no effects on the inhibition of the respiration could be observed within the range of solubility of the test item.
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.
