Examinations
- Maternal examinations:
- On day 20 of pregnancy all animals were sacrificed, dissected and observed for macroscopic pathological changes in maternal organs.
- Fetal examinations:
- On day 20 of pregnancy all animals were sacrificed. Live young were examined externally. The pups in each litter were then examined for visceral and skeletal malformations.
- Indices:
- In the controls, 500 and 1000 mg/kg groups, 1/20 mated animals. All the females from the high dose group were pregnant.
Results and discussion
Results: maternal animals
Maternal developmental toxicity
- Details on maternal toxic effects:
- Test item treatment in rats caused maternal toxicity (5/20 pregnant dams died, retarded body weight gain) at the highest dose tested (4000 mg/kg bw/day), when administered orally by gavage from day 6 to day 15 of pregnancy inclusively.

Applicant's summary and conclusion
- Conclusions:
- NOEL (maternal toxicity) = 1000 mg/kg bw/day
NOEL (development) = 1000 mg/kg bw/day - Executive summary:
The developmental toxicity of the substance was evaluated in an experimental study whereby groups of 20 gravid female CFY rats were administered 2.0 mL/100 g test item in sterile distilled water from day 6 to day 15 of pregnancy inclusively via oral gavage at concentrations of 500, 1000 and 4000 mg/kg bw/day for 20 days, alongside a vehicle control group tested in parallel.
As a result of maternal toxicity at highest dose level, litter weight and mean foetal weight were reduced, total resorptions were increased and delayed ossification of fetuses were observed. At 1000 mg/kg bw/day, it can be said that developmental effects occurred together with maternal toxicity effects, but not as a secondary non-specific consequence of maternal toxicity effects. At 500 and 1000 mg/kg bw/day there were no conclusive effects on either maternal or foetal parameters.
Based on the early resorptions, reduced body weight gain and mortality observed at the highest dose administered of 4000 mg/kg bw/day, the NOEL for maternal toxicity was set at 1000 mg/kg bw/day. Based on the delayed ossification, poor body weight and body weight gains and increased total resorptions of offspring at the highest dose, the NOAEL for developmental toxicity was expressed as 1000 mg/kg bw/day, however, it should be ruled out that it cannot be ruled out that these observations were effects of maternal toxicity.
