Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- water
- Controls:
- not required
- Amount / concentration applied:
- 0.5 g test material, moistened with 0.5 ml distilled water
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 72 hours
- Number of animals:
- 3
- Details on study design:
- 0.5 g of test material moistened with 0.5 ml of distilled wwater was introduced under a 2.5cm x 2.5cm cotton gauze patch and placed in position on the shorn dorsal/flank skin. The patch was secured in place with a strip of surgical tape. To prevent animals interfering with the patches, the trunk of each rabbit was wrapped in an elasticated corset.
After four hours of exposure, the corset and patches were removed and any residual test material removed by gentle swabbing with cotton wool soaked in distilled water.
Test sites were examined and scored for for evidence of primary irritation using the Draize scale, 1, 24, 48 and 72 hours after patch removal.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- The test material was not irritating to the skin of rabbits in this test.
- Executive summary:
The test material was evaluated for dermal irritation potential in three male New Zealand white rabbits, in accordance with OECD Test Guideline 404. The test material was applied to each animal at a dose of 0.5g, moistened with 0.5ml distilled water, and held in place using a semi-occlusive dressing. After four hours the patches and residual test material were removed. Test sites were observed for evidence of erythema and oedema 1, 24, 48 and 72 hours after patch removal.
There was no evidence of irritation, measured either as erythema or oedema, in any animal at any time point.
