Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Amount / concentration applied:
- 0.5 mL
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 24, 48 and 72 hours
- Number of animals:
- 3
- Details on study design:
- Approximately twenty-four hours prior to the commencement of the test, each of a group of three rabbits was prepared by closely clipping the fur from the dorsal/flank areas using veterinary clippers. Only animals with a healthy intact epidermis by gross observation were selected for the study. On the day of the test a suitable test site was selected on the back of each rabbit. A quantity of 0.5 ml of the test material was introduced under a 2.5 cm x 2.5 cm gauze patch and. placed in position on the shorn skin. The patch was secured in position over the test material with a strip of surgical adhesive tape (BLENDERM: approximate size 2.5 cm x 4.0 cm). To prevent the animals from interfering with the patches the trunk of each rabbit was wrapped in an elasticated corset (TUBIGRIP). The animals were then returned to their cages for the duration of the exposure period. Four hours after application the corset and patches were removed from each animal and any residual test material removed by gentle swabbing with cotton wool soaked in diethyl ether.

- Irritant / corrosive response data:
- No adverse dermal reactions were noted one hour after removal of the wrappings. Very slight erythema was noted at two treatment sites at the 24, 48 and 72-hour observations. The remaining treated skin site showed no evidence of erythema or oedema during this period.
Desquamation was noted at one treatment site at the 24-hour observation and at all treatment sites at subsequent 48 and 72-hour observations. - Other effects:
- Adverse dermal reactions on day seven were confined to desquamation at two treatment sites.
