Results based on critical effectPregnancy occurred in 25, 24, 24, and 21 females in the 0 (control), 50, 150, and 500 mg/kg/day dose groups, respectively. No differences in litter averages for corpora lutea, implantations, litter size, live/dead fetuses, early/late resorptions, percent resorbed conceptuses, or percent male fetuses were noted in any dose group.

Results based on critical effectIn a developmental toxicity study, four groups of 25 female Sprague-Dawley rats were exposed via oral gavage to a vehicle control (corn oil) or the test substance at concentrations of 0, 50, 150 and 500 mg/kg/day on gestation days (GDs) 7 through 17. No maternal or fetal mortalities occurred during the study. Maternal clinical signs consisted of excess salivation, urine-stained abdominal fur, red or brown substance on the forepaws, and alopecia in 4-9 rats at 500 mg/kg/day. Reduced maternal body weight gains and food consumption for the entire study period were noted in rats in the 150 and 500 mg/kg/day groups. Pregnancy occurred in 25, 24, 24, and 21 females in the 0 (control), 50, 150, and 500 mg/kg/day dose groups, respectively. Fetal weights were reduced in the 500 mg/kg/day group. No differences in litter averages for corpora lutea, implantations, litter size, live/dead fetuses, early/late resorptions, percent resorbed conceptuses, or percent male fetuses were noted in any dose group. Malformations occurred in 1, 0, 2, and 6 fetuses from 1, 0, 2, and 5 litters in the four respective dosage groups. Only malformations in the 500 mg/kg/day group, which included skeletal variations, were considered to be related to the test substance. Based on these results, the submission sponsor finds that the maternal NOAEL for the test substance is 50 mg/kg/day and the developmental NOAEL is 150 mg/kg/day.
