Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based upon the referred classification criteria, the test item is considered to be "not irritating" to rabbit skin.
Executive summary:

The primary skin irritation potential of the test item was investigated according to OECD test guideline no. 404. 0.5 g of the test item moistened with purified water was applied by topical semi-occlusive application of 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 dressing.

The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed.

Thus, the test item did not induce significant or irreversible damage to the skin.
