Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information
- Conclusions:
- Under the test conditions chosen and considering the described findings the test substance does not give indication of an irritant property to the skin.
- Executive summary:
The potential of the test substance to cause acute dermal irritation or corrosion was assessed by a single topical application of 0.5 ml to the intact skin of 3 White Vienna rabbits for 4 hours under semiocclusive dressing. The average score (24 to 72 hours) for irritation was calculated to be 0.9 for erythema and 0.0 for edema. The skin reactions were reversible within 8 days, thus the study was terminated.
