Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Under the conditions of the test, the EC50 of the test material was determined to be > 1000 mg/l and the NOEL was shown to be 1000 mg/l.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
In a GLP compliant study performed according to the standardised guideline OECD 209, the toxicity of the test material was determined in an activated sludge respiration inhibition test. Activated sludge was exposed to the test material for 3 hours at the following concentrations; 10, 100 and 1000 mg/l, after which the rate of respiration was calculated from the oxygen consumption.
The study was performed to a good standard and was assigned a reliability score of 1 using the principles for assessing data quality as set out in Klimisch (1997).
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.
