Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- not irritating according to Federal Register 38, No 187
no labelling according to EU guideline - Executive summary:
A group of six rabbits was clipped over a wide area on their backs approximately 24 hours prior to application. One side of the animals' backs was abraded at two sites with a lancet sufficiently deep to penetrate the stratum corneum but not enter the derma to produce bleeding. Two intact skin sites were also selected on the other side of the back.
A 0.5 g portion of the experimental material was applied to two abraded and two intact skin sites on the same rabbit. Gauze patches were then placed over the treated areas and an impervious material wrapped snugly around the trunks of the animals to hold the patches in place. The wrapping was removed at the end of the twenty-four hour contact period, the sites wiped but not washed, and the treated areas examined. Readings were also made after 72 hours. The Draize method of scoring was employed. All other lesions observed were recorded. No irritating effects were observed at any reading. The Mean Primary Irritation Score was: 0.3
