Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 750 mg/kg bw/day when dogs were treated with disodium 5-amino-4-hydroxy-3-(phenyldiazenyl)naphthalene-2,7-disulfonate.
- Executive summary:
In a chronic repeated dose toxicity study, dogs were treated with Disodium salt of 8-amino-2-phenylazo-1-naphtoL-3, 6-disulphonic acid in the concentration of 750 mg/kg bw/day orally in diet. Histopathological changes in the Liver, kidneys and thyroid were observed in 750 mg/kg/day treated dogs. As there in no other effect were observed .Therefore, NOAEL was considered to be 750 mg/kg bw/day when dogs were treated with Disodium salt of 8-amino-2-phenylazo-1-naphtol-3, 6-disulphonic acid orally for 90 days.
