Design outcomes

Primary

MeasureTime frameDescription
Erythema at the Patch Test Site is Evaluated for Each Participant3 weeksErythema Scoring Scale with 0 being no visible erythema and 5 being bullous reaction.

Secondary

MeasureTime frameDescription
Sensitization Reactions5 weeksErythema Scoring Scale with 0 being no visible erythema and 5 being bullous reaction. Allergic Dermal Sensitization Potential - Erythema will be evaluated at the patch site for only the test material (positive and negative control will not be evaluated). Sensitization reactions will be determined at the patch test site after a two week rest period for each participant (similar to a wash-out period). The patch test site will be tested on the same study subject population, but using a virgin test site.
