Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC10/EC50 (3 h): > 100 mg/L based on respiration inhibition (nominal; OECD 209)
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
One experimental study according to OECD 209 (GLP) is available investigating the toxicity of the test substance to activated sludge microorganisms (Spoo-Klöppel, 2015). The study was performed as a limit test with a concentration of 100 mg/L and activated sludge from a wastewater treatment plant treating predominantly domestic sewage. Test solutions were prepared by adding an appropriate amount of the test substance to the test vessel followed by stirring for 17 h and adjustment of pH to 7.1 - 7.4. After 3 h of incubation no inhibition of the respiration rate was recorded resulting in an EC10/EC50 (3 h) > 100 mg/L. Thus, no inhibition of the degradation process in conventional sewage treatment plants is 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.
