other: Waxy solid
Details on test material:
Lot #: 210111899. The test substance was stored at room temperature. Expiration Date: Not applicable.

Test animals

Species:
rat
Strain:
Sprague-Dawley
Sex:
female
Details on test animals or test system and environmental conditions:
Five female, nulliparous, non-pregnant rats. 9-10 weeks of age. 178-229 grams at experimental start.
Housing: The animals were singly housed in suspended stainless steel caging with mesh floors. Litter paper was placed beneath the cage and was changed at least three times per week.
Animal Room Temperature and Relative Humidity Ranges: 19-21°C and 30-69%, respectively.
Animal Room Air Changes/Hour: 13. Airflow measurements are evaluated regularly.
Photoperiod: 12-hour light/dark cycle.
Acclimation Period: 9-20 days.
Food: Harlan Teklad Global 16% Protein Rodent Diet® #2016. The diet was available ad libitum, except during fasting.
Water: Filtered tap water was supplied ad libitum by an automatic water dispensing system.
Contaminants: There were no known contaminants reasonably expected to be found in the food or water at levels which would have interfered with the results of this study. Analyses of the food and water are conducted regularly.



Administration / exposure

Route of administration:
oral: gavage
Vehicle:
CMC (carboxymethyl cellulose)
Details on oral exposure:
The test substance was administered as a 40% w/w mixture in 0.5% w/v solution of CMC in distilled water to the stomach using a stainless steel ball-tipped gavage needle attached to an appropriate syringe. Following administration, each animal was returned to its designated cage. Feed was replaced approximately 3-4 hours after dosing.
Doses:
The rats were each dosed at 2,000 mg/kg of body weight.
No. of animals per sex per dose:
1
Control animals:
no
