Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- water
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount applied: 0.5 g, based on the dry weight - Duration of treatment / exposure:
- 4 hours
- Observation period:
- 72 hours after patch removal
- Number of animals:
- 6 rabbits (1 male, 5 females)
- Details on study design:
- TEST SITE
- 24 h before: Dorsal area of the trunk of each animal was clipped free of hair
- Area of exposure: approximately 10 x 15 cm
- Test item was placed under a 2.5 x 2.5 cm surgical gauze patch moistened with distilled water
- Gentle pressure was applied to the gauze to aid in the distribution of the test item
- Patch was secured with non-irritating tape
- Type of wrap: Torso was wrapped with plastic in a semi-occlusive manner and secured with non-irritating tape which completely covered the plastic.
REMOVAL OF TEST SUBSTANCE
- Washing: Residual test item was gently washed with distilled water from the dose site prior to dermal observations.
OBSERVATIONS
- Duration of observation period following administration: 72 hours
- Test sites were scored for dermal irritation at 30 to 60 minutes post patch removal and again at 24, 48 and 72 hours post patch removal using the numerical Draize scoring code. The skin was also evaluated for ulceration and necrosis or any evidence of tissue destruction. Additional signs were described.
- The general health status of the animals was monitored at each observation time.
- Frequency of weighing: recorded pretest
