Test animals

Species:
rabbit

Test system

Type of coverage:
occlusive
Preparation of test site:
clipped
Vehicle:
unchanged (no vehicle)
Amount / concentration applied:
0.5 ml
Duration of treatment / exposure:
24 hrs
Observation period:
48 hrs
Number of animals:
6
Details on study design:
Six male albino rabbits were clipped free of hair on the trunk and lateral area and placed in FDA-type stocks. Doses of 0.5 ml of undiluted test material were applied to intact skin under 1 ½ inch x 1 ½ inch 12-ply gauze squares. Rubber sheeting was then loosely wrapped around the trunk and secured with adhesive tape. After 24 hours, the rabbits were removed from the stocks, the patches taken off and the reactions observed. Observations were also made at 48 hours.
