Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 toxicity to microorganisms was assessed with the test item at nominal concentrations of 100 mg/L for 30 min. The EC50 was > 100 mg/L (nominal).
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
The activity of activated sludge was determined by measuring the respiration rate under defined conditions according to EU-method C.11. The respiration rate of the activated sludge was not or only slightly inhibited (> 10 %) up to the highest tested concentration of nominal 100 mg test substance/L. Therefore, the 30-min EC 50 is clearly higher than 100 mg/L under the present test conditions and the NOEC is 100 mg/L.
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.
