- Details on study design:
- An area of at least 6 cm2 was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (20 cm2) bearing 0.5 g of the test substance was applied to the flank. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water containing 0.5% carboxymethylcellulose and 0.1% polysorbate 80. The patches were loosely covered with aluminum foil held in place for by an adhesive tape. The animals were checked daily for systemic symptoms and mortality.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- The test item is considered to be "not irritating" to rabbit skin.
- Executive summary:
The primary skin irritation potential of the test substance was investigated according to OECD test guideline no. 404. The test item was applied by topical application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the patches. The test item induced slight erythema reactions when applied to albino rabbit skin. The reactions were observed only one hour after removing the
bandages. Because the mean values of the recordings 24 to 72 hours after application are scored zero, the test substance can be classified as non-irritant.
