Details on maternal toxic effects:
Maternal uteri examined for fetal resorption showed no significant increase compared with dams who received no saccharin.
Results (fetuses)

- Embryotoxic / teratogenic effects:no effects
Details on embryotoxic / teratogenic effects:
None of the fetuses from dams treated with saccharin showed significant increases in either external or internal malformations when compared to controls.
Effect levels (fetuses)

- Based on:
- test mat.

Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 2000 mg/kg bw in female ICR albino mice and their offspring when they the pregnant females were exposed to saccharin
- Executive summary:
In a teratogenicity study, the toxic effects of saccharin was evaluated in pregnant female ICR albino mice. The dams received saccharin in drinking water at a dosage of 0, 500, 1000 or 2000 mg/kg bw from day 0 to day 17 of gestation. The results showed no significant increase for fetal resorption in the maternal uteri as compared with dams who received no saccharin. None of the fetuses from dams treated with saccharin in drinking water showed significant increases in either external or internal malformations when compared to control. Therefore, NOAEL was considered to be 2000 mg/kg bw in the maternal F0 generation and in the F1 generation after administration of saccharin in drinking water from day 0 to day 17 of gestation.
