Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 mL, i.e. 500 mg moistened with water - Duration of treatment / exposure:
- First rabbit: 3 minutes (left side), 1 hour and 4 hours (right side)
Based on the results of first rabbit (product not very irritating) 2 other animals were tested: 4 hours exposure. - Observation period:
- 1, 24, 48 and 72 hours after removal of the test substance
- Number of animals:
