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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not readily biodegradable
Key value for chemical safety assessment
Additional information
A study conducted on the Similar Substance 01 is available, in order to assess the biodegradation potential in water by microorganisms.
In the performed study, a reduction of the test substance was identified by DOC removal by adsorption from the bacterial sludge, quantified at ca. 90 - 100 % after 24 hours. Therefore, the present reduction does not necessarily mean a degradation of the test substance.
Biodegradation was therefore further investigated with the following approaches:
- The assessement of the chemical structure of the substance, according the work of Koichi H. et al. (2000), reported the presence of multiple functional groups linked with no readily biodegradability potential.
- The evaluation of the substance by the EPISuite-BioWin module reported a "not readily biodegradable" prediction.
- An assessment of other structurally similar chemicals (i.e. metal complex azo dyes) belonging to the same category, reported that the substance should not be neither inherently nor readily biodegradable.
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.
