Description of key information
Two GLP guideline studies were performed, one following EU Method C.4-B (Determination of the "Ready" Biodegradability - Modified OECD Screening Test), and the other following OECD guideline 301C (Ready Biodegradability: Modified MITI Test(I)). No biodegradation was observed.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- freshwater
Additional information
A study was performed to assess the ready biodegradability of test substance Reactive Navy FC63805 according to EU Method C.4-B (Determination of the "Ready" Biodegradability - Modified OECD Screening Test) in compliance with GLP. The test substance was dissolved in a mineral medium and inoculated with a mixed population of aquatic organisms and subsequently incubated for 28 d under aerobic conditions. During this period biodegradation was determined by reduction of DOC. The results (0 % DOC removal after 28 days) indicate that Reactive Navy FC63805 is not readily biodegradable.
An additional study was performed following the OECD guideline 301C (Ready Biodegradability: Modified MITI Test(I)), also under GLP. The test substance was exposed to activated sludge for 28 days and degradation was measured by the biochemical oxygen demand and dissolved organic carbon content. The results (0 % degradation based on BOD, 2 % degradation based on DOC) indicate that Reactive Navy FC63805 is not readily biodegradable.
