Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
No skin irritation was observed throughout the study.
Executive summary:

A primary skin irritation test was conducted with rabbits to determine the potential for the test substance to produce irritation after a single topical application in accordance with OECD guideline 404. Five-tenths of a gram of the test substance was moistened with distilled water and applied to the skin of three healthy rabbits for 4 hours. The dose site was evaluated for dermal irritation by the method of Draize immediately after patch removal and at 30-60 minutes and 24, 48, and 72 hours after patch removal.

There was no dermal irritation noted for any treated site during this study.
