Description of key information
IC50 at 3h > 100 mg/L
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
Additional information
IC50 has been calculated as the respiration rate of each test concentration as a percentage of the mean of the two control respiration rates; for the read across substances Similar substances 01 and 03 was valued as > 100 mg/L at 3 hours. All of the three studies available results are comparable.
Therefore, toxicity to microorganisms of Direct Black 22 is unlikely, given that the abovementioned tests indicate as no toxic.
