Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test item showed no skin irritation potential in the study according to OECD Guideline 404.
Executive summary:

To test for primary skin irritation, 0.5 g of the test material was mixed with some drops of aqua pro injectione to ensure good contact to the skin, spread onto patches, and then applied to the intact skin of three previously shaven rabbits for a 4-hour period under semiocclusive conditions.

The first examination of the treated skin sites followed 1-hour after removal of the patches. Then, examinations were performed daily for further 7 days. Under the given experimental conditions no irritations in the treated areas were observed. Therefore, the test item is not considered to be irritating to skin.
