Description of key information
IC50, 3h > 100 mg/l
Key value for chemical safety assessment
Additional information
The analogue substance was tested for toxicity to microorganisms following EC 87/302 (NONS dossier, 1991). Under the experimental conditions the IC50, 3h is > 100 mg/l.
Based on the read across consideration same results apply to Direct Blue 267:1.
