- clipped
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit):Each animal was treated by dermal application of 0.5 g of the test substance. - Duration of treatment / exposure:
- Four hours
- Observation period:
- 72 hours
- Number of animals:
- 3 males
- Details on study design:
- TEST SITE
- Area of exposure: The test substance was applied to the skin of one flank.
- Coverage: Approximately 2x3 cm
- Type of wrap if used: Applied to the skin on a metalline patch. This patch was mounted on micropore tape, which was wrapped around the abdomen and secured with a Coban elastic bandage.
