Applicant's summary and conclusion
- Conclusions:
- The end point for the dermal repeated dose toxicity study was found to be No Observed Adverse effect level (NOAEL) at 1428.5 mg/kg of FD&C Red No. 4 (4548-53-2) when treated to mice.
- Executive summary:
Repeated dermal dose toxicity test was performed on Swiss Webster mice for 19.5 months. 50 animals per sex were used and the distilled water was the vehicle.100 female and 100 male mice were used in each control group.
First the hair was removed and to the depilated area dosage was applied. Each mouse was observed daily for behavior, survival and visible or palable growth.
No abnormalities were observed in treated group as compare with control group and no significant change was observed in gross or histopathology.
Therefore, from the study it was found that the end point for the dermal repeated dose toxicity study was found to be No Observed Adverse effect level (NOAEL) at 1428.5 mg/kg of FD&C Red No. 4 (4548-53-2) when treated to mice.
