Applicant's summary and conclusion

Conclusions:
Allyl hexanoate produced 13 cases of sensitization (out of 25) and should be considered a moderate sensitizer.
Executive summary:

10 male and 15 female volunteers completed the study. Following a 24-hour pre-treatment with 5 % aqueous sodium lauryl sulfate under occlusion, the pure test material was applied under occlusion to the volar forearms of all subjects for 48 hour periods. The challenge sites were read on removal of the patch (after 48 hour exposure) and 24 hours thereafter.
