Constituent 1
Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Acclimatization period: At least 5 days before the beginning of the study.
ldentification of the animals: Ear tattoo
Age at the beginning of the study: About 8 months
Body weight range at the beginning of the study: 3.55 - 3.82 kg
The animals were housed in fully air-conditioned rooms, in which a central air-conditioning system ensured a temperature in the range of 20 - 24°C and a relative humidity in the range of 30 - 70%. The day/night rhythm was 12 h light and 12 h darkness.
Single housing in stainless steel wire mesh cages with grating, floor area: 3000 cm2.
Type of diet: Kliba-Labordiaet, Provimi Kliba SA, Kaiseraugst, Switzerland (about 130 9/animal per day)
Watering: Tap water ad libitum
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: untreated skin of the same animal
- Amount / concentration applied:
- 0.5 ml
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 7 days
- Number of animals:
- 3
- Details on study design:
- Clipping of the fur: At least 24 hours before the beginning of the study clipping of the dorsolateral part of the trunk of the animals.
Application area: 2.5 x 2.5 cm
Application site: Upper third of the back or flanks
Readings: About 1 h, 24 h, 48 h and 72 h and 7 days after removal of the test patch.
