Study design
The test item was mixed with some drops of Aqua pro injectione to ensure good contact with the skin. Afterwards, the test material was spread onto patches and applied to the intact skin of previously shaven rabbits for 4 hours under semiocclusive conditions. The study was performed initially with one animal and followed by the confirmatory test with two further animals. The first examination of the treated skin was 1 hour after patch removal. Thereafter, examinations were performed daily for a further 7 days.
Results
Under the conditions of the present study, no signs of irritation were seen. Body weight development of the treated rabbits was inconspicuous.
Conclusions
No skin irritating potential could be detected.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No skin irritating potential could be detected.
- Executive summary:
This study was performed according to GLP and methods applied are fully compliant with OECD TG 404. For the test item no irritating potential could be detected.
