Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In an activated sludge respiration inhibition test performed according to OECD/EC test guidelines, the EC50 was determined to be >100 mg/l and the EC10 >=100 mg/l.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
In an activated sludge respiration inhibition test performed according to OECD/EC test guidelines, a loading rate of 100 mg/l substance was used. The activated sludge of a predominantly domestic sewage did not show significant inhibition of the respiration rate, at 100 mg/l 11% and 0% inhibition was measured. Hence, the EC50 of 2-amylanthraquinone exceeded a loading rate of 100 mg/l, while the EC10 was determined to be >=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.
