- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Age at study initiation: adult
- Weight at study initiation: females 2.8-3.5 kg
- Housing: individually
- Diet ad libitum
- Water ad libitum
- Acclimation period: 14 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20
- Humidity (%): 50
- Air changes (per hr): 10
- Photoperiod (hrs dark / hrs light): 12 /12
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: the opposite side of the flank served as control
- Amount / concentration applied:
- 500 mg moistened with water
- Duration of treatment / exposure:
- 4 h
- Observation period:
- planed up to 14 days but terminated after 7 d because up to then no effects were observed
- Number of animals:
- 3
- Details on study design:
- Approximately 24 hours before the test, the fur was removed by shaving from the dorsal area of the trunk of the animal . Only animals with health intact skin were used. A dose of 500 mg was applied to the test site moistened sufficiently with water to ensure good contact with the skin. The test site was then covered with a gauze patch. The patch was held in contact with the skin by means of semi-occlusive dressing for the duration of the exposure period. The opposite untreated skin served as a control. Exposure time was 4 hours. After termination the exposure period the coverage was removed and . the skin sites were evaluated for erythema and edema. Scores according to Draize were taken 24. 48, and 72 hours after patch removal for erythema and edema formation

- not irritating
- Remarks:
- Migrated information
- Executive summary:
According to OECD TG 404 and GLP 3 female Himalayan rabbits received dermal application on the shaved back for 4 hours held in place by semi-occlusive dressing, 60 min, 24, 28, and 72 hiours after removal of the dressing the treated area was examined and the effects scored according to Draize. None of the animals showed erythema or edema. Therefore theMacrolex Gelb G was evaluated to be non-irritating to the skin of rabbits.
