Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A screening study was performed resulting in almost complete inhibition at 1000 mg/l, but only 24% at 100 mg/l.
The EC50 is in the range of 100 - 1000 mg/l, but is recorded as 100 mg/l for risk assessment purposes.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
- EC10 or NOEC for microorganisms:
- 10 mg/L
Additional information
A screening study was performed resulting in almost complete inhibition at 1000 mg/l, but only 24% at 100 mg/l. The EC50 is in the range of 100 - 1000 mg/l, but is recorded as 100 mg/l for risk assessment purposes.
It was not considered scientifically useful to perform further replicates to establish a precise EC50, as inhibition at concentration likely to be found in water treatment or used for biodegradation are apparently of low toxicity.
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.
