Applicant's summary and conclusion
- Conclusions:
- The substance 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid (Acid Red 92) (CAS Number: 18472-87-2) is non mutagenic in the In vivo Mammalian Erythrocyte Micronucleus Test performed.
- Executive summary:
Genetic toxicity in vivo study was performed for the test chemical3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid (Acid Red 92) (CAS Number: 18472-87-2) on male and female NMRI mice. Acid red 92 was injected intraperitoneally in mice and the number of micronucleus formed in the polychromatic erythrocytes was noted.
The positive control (CPA) induced 2.030 % of MN in PCEs (0.08 % in the control animals: significance p 0.0040).
In the treated animals with 100 mg/kg a percentage of MN 0.150 (24h) and 0.110 (48h) was observed: these values, although higher than the control, had a p > 0.34. A reduction of PCE was observed, thus indicating a cytotoxic effect of the test item in the bone marrow cells.
Acid Red 92 is non mutagenicintheIn vivo Mammalian Erythrocyte Micronucleus Test performed.
In accordance with the CLP classification, 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid (Acid Red 92) (CAS Number: 18472-87-2)is non mutagenic.
