- RANGE FINDING TESTS:
material was pretested on five subjects in order to determine if SLS pretreatment was needed. A patch was applied to normal site on the backs for 48 hours under occlusion. No subject had any rritation from the material and it was decided to use SLS-pretreatment in the test.

Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitizing
- Remarks:
- based on criteria outlined in CLP (1272/2008/EC)
- Conclusions:
- Under the conditions of this study, the testing material gave no instances of contact-sensitization. Based on this result, the test substance does not need to be classified for skin sensitization in accordance with the criteria outlined in CLP (1272/2008/EC).
- Executive summary:
The sensitizing potential of Copaiba oil on humans was tested in a maximization test on 25 healthy adult volunteers. The testing material was pretested to determine whether Sodium Lauryl Sulfate (SLS) pretreatment was required. No subject had any irritation from the testing material. In the maximization test all subjects were pretreated with 5% SLS (the patch sites were pretreated for 24 hours). The material was applied under occlusion on the forearms for five alternate day-48 hour periods. Following a ten-day resting period challenge patches were applied for 48 hours (the challenge sites were pretreated for 24 hours with 10% SLS). The challenge site was read on removal of the patch and after 24 hours. Under the conditions of this study, the testing material gave no instances of skin sensitization.
Based on this result, the test substance does not need to be classified for skin sensitization in accordance with the criteria outlined in CLP (1272/2008/EC).
