Details on study design:

Viability / Mortality: Daily during the acclimatization period, during the first 30 minutes and at approximately 1, 2, 3 and 5 hours after administration on test day 1 (in common with the clinical signs) and twice daily during days 2-15.

Clinical Signs: Daily during the acclimatization period, during the first 30 minutes and at approximately 1, 2, 3 and 5 hours after administration on test day 1, depending on the occurrence of clinical signs of toxicity. Once daily during days 2-15.

Body Weights: On test days 1 (prior to administration), 8 and 15.

All animals were killed at the end of the observation period by carbon dioxide asphyxiation and discarded after macroscopic examinations were performed. No organs or tissues were retained

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The median lethal dose of Sorbitanmonocaprylat after single oral administration to female rats, observed over a period of 14 days, is:
LD50 (female rat): greater than 2000 mg/kg body weight.

Executive summary:

Two groups, each of three female HanRcc:WIST (SPF) rats, were treated with sorbitan caprylate by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was formulated in PEG 300 at a concentration of 0.2 g/mL and administered at a dosing volume of 10 mL/kg.

The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2-15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15.

All animals were necropsied and examined macroscopically.

All animals survived until the end of the study period.

No clinical signs were observed during the course of the study.

The body weight of the animals was within the range commonly recorded for this strain and age.

No macroscopic findings were recorded at necropsy.

The median lethal dose of sorbtian caprylate after single oral administration to female rats, observed over a period of 14 days, is: LD50 (female rat): greater than 2000 mg/kg body weight.
