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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Neither readily nor inherently biodegradable
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
There are no information about the biodegradablity potential of Acid Red 336, thus the available data on structural analogous Similar Substance 01 have been taken into account (details and explanations are included in the report attached to the IUCLID section 13).
The inherently biodegradability potential of similar substance 1 was assayed in Modified Zahn-Wellens Test, according to the OECD guideline 302B. Under test conditions, test item attained 7 % degradation after 28 days and therefore cannot be considered as inherently biodegradable. The standard material, Digol, attained 100 % degradation after 28 days, thereby confirming the suitability of the inoculum and culture conditions.
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.
