Description of key information
Direct Blue 094 is not expected to be readily biodegradable, but to have inherent, primary biodegradation potential.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, fulfilling specific criteria
- Type of water:
- freshwater
Additional information
Direct Blue 094 has been investigated for biodegradation in different studies evaluating Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) and inherent biodegradability.
The BOD5 and COD for FAT 11127/A were found to be 0 mg O2/g, and 332 mg O2/g respectively. Similarly, BOD5 and COD of FAT 11127/B was found to be 0 mg O2/g, and 466 mg O2/g, respectively. BOD5/COD ratios for both FAT 11127/A and 1127/B are zero, indicating that ready biodegradation cannot be expected.
FAT 11127/A was evaluated for biological elimination in a study conducted using test method FC 2.463, 1-7.1973. The bioelimination of the test substance was 10 %, hence it can considered to be not inherently biodegradable.
FAT 11127/C was found to bioeliminate 32.9 % after 28 days in a Zahn-Wellens-Test conducted according to OECD Guideline 302B and EEC-Directive, L133.
Hence, it can be concluded that under the test conditions, FAT 11127/C demonstrated inherent, primary biodegradability.
Based on the above information, Direct Blue 094 can be expected to have some inherent biodegradation potential, however, it is not expected to be readily biodegradable.
