Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 920 mg/kg/day for F0 and F1 generation when Wistar female rats treated with 3,4,5,6-tetrachloro-2- (1,4,5,8-tetra bromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid (Food dye Red No.104 / phloxine) (CAS No.18472-87-2).
- Executive summary:
In a developmental toxicity study, wistar female rats treated with 3,4,5,6-tetrachloro-2 -(1,4,5,8-tetra bromo-6-hydroxy-3-oxoxanthen-9 -yl)benzoic acid (Food dye Red No.104 / phloxine) (CAS No.18472-87-2) in the concentrations of 0, 280, 920, 2870 mg/kg/day (0, 0.3, 1.0 and 3.0 %) during gestation orally by feed. No toxic symptoms were observed in treated rats. No effect on food consumption and water consumptions were observed in treated rats. Slight decrease in body weight gain and decrease in food efficiency and decrase in body lenght was observed in 2870 mg/kg/day treated offsprings as compared to control. No significant effects were observed in number of corpora lutea or implantations and the rate of nidation, organ weights and gross pathology in treated female rats as compared to control. No effect were observed on litter size and fetal mortality. Significantly decrease in body weight was observed in female offspring at 2870 mg/kg/day. Significant effect were observed in lung weight of male rats at 920 mg/kgbw/day as compared to control.The observed change in lung weight were not remarkalbe. No effect on tail lenght and gross pathology were observed in offspring. During prenatal development , slight increase in nucleus with deformed shapes and low stainability in sternebrae and decreases in the number of metacarpus and coccygeal vertebrae were observed. These findings may suggest a retardation of ossification in fetal stage, but such changes were not observed in rats examined after weaning.
Therefore, NOAEL was considered to be 920 mg/kg/day for F0 and F1 generation when Wistar female rat treated with 3,4,5,6-tetrachloro-2- (1,4,5,8-tetra bromo-6-hydroxy-3 -oxoxanthen-9-yl)benzoic acid (Food dye Red No.104 / phloxine) (CAS No.18472-87-2) orally by feed.
