Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitizing
- Conclusions:
- The test material was considered to be not sensitizing to the skin of human volunteers.
- Executive summary:
A Human maximization test of test chemical was conducted on 24 volunteersto assess its skin sensitization potential.
None of the volunteers had developed any signs of skin sensitization. Hence the test chemical wasconsidered to be not sensitizing to theskin of human volunteers.
