Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 1000mg/kg bw. When Multi-generation reproduction studies with D & C Red no. 27 (13473-26-2) was performed in rats orally.
- Executive summary:
Multi-generation reproduction studies withD & C Red no. 27 (13473-26-2) were performed in rats. Test material in dose concentration not excess 1000mg/kg was given in diet. Dose was calculated on the bases of previous long term feeding study in rats and dog.Data through the parental generation and F2b Litter give no indication of adverse effects on reproductive performance. Hence NOAEL was considered to be 1000mg/kg bw. When Multi-generation reproduction studies withD & C Red no. 27 were performed in rats orally.
