Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Under standard test conditions no readily biodegradation was observed.
In Robama study (Riva, 2000) Direct Black 22 (DBk22) was tested to determine the biodegradation in 28 days, at 80% active material and results showed that substance is not ready biodegradable. This result can be consider reliable and appropriated.
Furthermore this conclusion has been confirmed by read across with the Similar Substance 01 that resulted not inherently biodegradable in experimental study (Haner, 2007) and that has been resulted not biodegradable in any of the further three tests conducted respectively for inherent and ready biodegradability reported in literature (Pagga et al, 1986).
Based on CSR and reported risk management measures, direct and indirect exposure of sediment and soil to DBk22 is unlikely; since no exposure of the aquatic compartment is foreseen and thus subsequent sediment and/or soil exposure can be excluded.
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.
