Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicity to microorganisms
Administrative data
Link to relevant study record(s)
Description of key information
The NOEC after 3 hours exposure was 180 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 590 mg/L
- EC10 or NOEC for microorganisms:
- 180 mg/L
Additional information
A reliable toxicity study with microorganisms is available for FX511 and is included in this dossier.
Clark (2012) conducted a reliable (Klimisch 1) GLP compliant study according to OECD 209 methods. Activated sludge was exposed to FX511 at nominal concentrations of 100, 180, 320, 560 and 1000 mg/L for 3 hours. The effect of the test item on the respiration of activated sewage sludge resulted in a 3-hour EC50 value of 590 mg/L. The NOEC after 3 hours exposure was 180 mg/L. Consequently, this value will be taken for the toxicity of FX511 to microorganisms endpoint.
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.
