Applicant's summary and conclusion

Interpretation of results:
other: Not irritating
Conclusions:
The test chemical was considered to be not irritating to the skin of human subjects.
Executive summary:

Skin irritation study of the given test chemical was conducted on human subjects to determine the degree of skin irritancy. Each subject was treated with 4% of test chemical in petrolatum dermally for 48 hours under a closed path patch. Since no known signs of irritation were observed, the chemical was considered to be not irritating to the skin of human subjects.
