Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water solution as test item showed 49.0 % respiration inhibition of activated sludge after a test period of 3 hours at the highest concentration of 1000 mg/L. Therefore an EC50 of 978.2 mg/L could be calculated for the water solution as test substance.
As the content of the active ingredient in the water solution is 36.5% the effect concentrations can be calculated for the pure and solid substance as EC50= 357.0 mg/L and EC10= 31.03 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 357 mg/L
- EC10 or NOEC for microorganisms:
- 31.03 mg/L
Additional information
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.
