Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Criteria used for interpretation of results: expert judgment
- Conclusions:
- Five and ten percent test item were mildly irritating when applied under continuous occlusion on normal skin. The latter mode of exposure is, of course, greatly exaggerated in relation to normal use.
- Executive summary:
The 10-day occlusive patch test method was used as follows: 1, 5 and 10% concentrations of the test item were applied daily to the forearms of 10 young-adult female college students. 1% of the test item produced no visible reaction in any of the subjects. By the sixth day, some of the volunteers treated with 5% of the test item began to exhibit mild erythema which gradually worsened thereafter. The results with 10% were indistinguishable from the 5% concentration. 5 and 10% test item are mildly irritating when applied under continuous occlusion. The latter mode of exposure is, of course, greatly exaggerated in relation to normal use.
