Description of key information
A toxicity study of FAT 21036/B to activated sludge was determined in a 3-hours growth inhibition test according to OECD Guideline 209. The test substance concentrations tested were 40, 128 and 400 mg/l. No inhibition was seen at any of the test concentrations. Hence, the IC50 (3 h) of the test substance FAT 21036/B was found to be >400 mg/L. The findings of the supporting study where the IC50 was found to be >300 mg/L, also support the conclusion that Acid Blue 225 has low toxicity potential for microbial population.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 400 mg/L
