Description of key information
Not readly biodegradable
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Under standard test conditions in Dystar reports (1998) MG did not show to be readily biodegradable (0.3%, 14 days, OECD 301C). This value is confirmed by EpiSuite prediction and by the result of the analogous substance Crystal Violet 4. An indication of inherent biodegradation is given by Dystar reports (1998) where a value of 82% of degradation in Zahn-Wellens test is reported, but any detail is missing about time and testing 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.
