Applicant's summary and conclusion

Interpretation of results:
other: Not skin irritating
Conclusions:
Test material was considered to be not skin irritating in a pre test for human maximization assay.

Executive summary:

 

A pre-test for human maximization was performed to assess the dermal irritation potential of test chemical. The test chemical 10% in petrolatum was applied to the back of 26 male volunteers in a closed patch for 48 hours. The volunteers were observed for signs of irritation. No signs of irritation were noted in the volunteers after 48 hours. Hence, test material was considered to be not skin irritating in a pre test for human maximization assay.
