Irritation

The Skin Technology Center performs studies of the irritancy potential of topical antimicrobial products by means of multiple applications (15 or more) of a product beyond those necessary to demonstrate the antimicrobial efficacy of a healthcare personnel hand cleanser per the FDA Tentative Final Monograph [FR 43:4, 06 Jan 78, p. 1244].  The additional applications are not preceded by applications of the challenge bacterial suspension.  The evaluations are performed visually and, in some studies, by means of the instrumentation described in our Skin Moisturization capabilities.
