Applicant's summary and conclusion

Conclusions:
No Observed Adverse Effect Level (NOAEL) for reproductive toxicity was considered to be 75 mg/kg/day, and the dose-level of 75 mg/kg/day was considered to be the LOAEL for embryo-foetal toxicity. When female wistar rats were treated with Salicylic acid (69-72-7) orally.
Executive summary:

Reproductive toxicity study of Salicylic acid(69-72-7)was performed on female wistar rats.80 rats were divided as 20 rats /dose group.Test material mixed with0.5% solution of sodium carboxymethyl cellulosewere administered in dose concentration 0,75, 150, or 300 mg/kgfrom day 8 through day 14 by oral gavage route.The control group was given 5 ml/kg of vehicle. On day 20 of gestation, 15 of the animals of each group were killed; the remaining 5 were allowed to deliver. The offspring, which were weaned on day 21, were observed daily and weighed every 3 days. Offspring were killed and autopsied on the 56thday for examinations of visceral and skeletal abnormalities

 

Maternal body weight gain was inhibited for animals of the 300-mg/kg group. Salivation and/or piloerection were observed in this group. Feed and water consumption decreased during the administration of 300 mg/kg Salicylic Acid. Three animals of this group died within a few days of the initiation of dosing. Decreased uterine weight was observed in animals of the 150- and 300-mg/kg dose groups as compared to controls; these groups had 25.7% and 100% fetal mortality, respectively. Litter size and neonatal body weight, body length, and tail length were significantly decreased in the 150-mg/kg dose group. The incidences of external, internal, and skeletal anomalies in offspring autopsied at the 56th day were 1.8%, 0%, and 2.5%, respectively, for the 75-mg/kg group and 27.8%, 12.7%, and 65.7%, respectively, for the 150-mg/kg group.The offspring from animals of 150-mg/kg Salicylic Acid group had decreased body length and tail length compared to controls. The thyroid weight of male offspring from the 75-mg/kg group was significantly increased and the adrenal gland weight of male offspring from the 150-mg/kg group was significantly decreased compared to controls. The incidences of external organ, internal organ, and skeletal anomalies in offspring were 0%, 5.0%, and 0%, respectively, for the 75-mg/kg group and 13.7%, 17.2%, and 79.2%, respectively, for the 150- mg/kg group. Hence No Observed Adverse Effect Level (NOAEL) for reproductive toxicity was considered to be 75 mg/kg/day, and the dose-level of 75 mg/kg/day was considered to be the LOAEL for embryo-foetal toxicity.When femalewistar rats were treated withSalicylic acid(69-72-7)orally.
