Applicant's summary and conclusion
- Conclusions:
- The No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity is considered to be 1000 mg/Kg/day. When male and female Crl:CD (SD) were treated with Pigment yellow 13 (3520-72-7) orally.
- Executive summary:
Combined repeated dose and reproduction / developmental screening was performed to evaluate the toxic nature of Pigment Orange 13. Male and female Crl:CD (SD) were used in the study. The test compound was dissolved in water and used at dose levels of 0, 40, 200 or 1000 mg/Kg/day. The male rats were treated for 42 days and female rats were treated for 41-47 days. Recovery group of 0 and 1000 mg/Kg/day was also included in the study. The treated animals were noted for clinical signs, functional battery observations, body weight, food consumption, urinalysis, haematology, blood chemistry, organ weight changes and histopathology reproductive and developmental parameters. No adverse effects were noted in the various parameters studied. Based on the observations made,The No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity is considered to be 1000 mg/Kg/day. When male and femaleCrl:CD (SD)were treated with Pigment yellow 13(3520-72-7)orally.
