- Water: Ad libitum
- Acclimation period: A period of between 5 and 7 weeks.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 16 - 22 °C
- Humidity (%): Humidity was not actively controlled, but was expected to remain within the range of 40 to 80 % RH.
- Air changes (per hr): 10
- Photoperiod (hrs dark / hrs light): 12 h dark/12 h light.
Test system

- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount applied: 500 mg. Skin was moistened with water prior to application. - Duration of treatment / exposure:
- The sentinal was dosed for 3 min, 1 h and 4 h.
Two further rabbits were subjected to single 4 h applications. - Observation period:
- Three days
- Number of animals:
- Three
- Details on study design:
- TEST SITE
- Area of exposure: 30 x 20 mm
- Type of wrap if used: The test sites were covered iwth a dense gauze patch (30 x 20 mm) which was in turn covered by a larger gauze patch (40 x 40 mm) and an open-weave, elasticated adhesive bandage which was wrapped firmly around the torso to secure the applied dose and patch to the correct position.
REMOVAL OF TEST SUBSTANCE
