Evaluation of dermal reactions at the application sites will be assessed clinically using a visual scale that rates the degree of erythema, edema and other signs of cutaneous irritation.\n\nFollowing induction, subjects will have a 10 to 14-day Rest Phase, after which they will enter the Challenge Phase, which consists of one 48-hour application to a naive site on the opposite side of the back. Observations at the naive site during Challenge and the patterns of reactivity during the Induction Phase will provide a basis for an interpretation of contact sensitization.\n\nA total of 10 applications will be made over a period of approximately 6-8 weeks.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
