Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: Draize classification criteria, 1959
- Conclusions:
- Mild irritant
- Executive summary:
A single 4-hour, semi-occluded application of the test material to the intact skin of three rabbits produced very slight erythema. Two treated skin sites appeared normal at the 72-hour observation and the remaining treated skin site appeared normal at the 7-day observation. The test material produced a primary irritation index of 0.7 and was classified as mild irritant to rabbit skin according to Draize classification scheme. No corrosive effects were noted.
