Applicant's summary and conclusion

Interpretation of results:
other: not sensitizing
Conclusions:
The test chemical 4% in petrolatum did not induce any sensitization reactions on the skin of 23 human volunteers.
Hence, the test chemical was considered to be not sensitizing to skin.
Executive summary:

A human maximization test was carried out to assess the dermal sensitization potential of the test chemical. The test chemical 4% in petrolatum was applied to the skin of 23 human volunteers and observed for signs of dermal sensitization (duration of exposure, observation period not specified).

The test chemical 4% in petrolatum did not induce any sensitization reactions on the skin of 23 human volunteers.

Hence, the test chemical was considered to be not sensitizing to skin.
