Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Disperse Brown 19 was assessed in an OECD 302C test and not found to be inherently biodegradable (0% based on O2 consumption after 14 d). The structural analogue substance SA02 was used as key study. As almost all disperse dyes, the substance was not found to be readily biodegradable in an OECD 301B test (4% based on CO2 evolution after 28 d). Summarising, Disperse Brown 19 is neither considered readily nor inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
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.
