Abstract
A method that includes the step of applying an isothiocyanate functional surfactant containing composition to a skin where the isothiocyanate functional surfactant containing composition includes an isothiocyanate functional surfactant where the protonated form of the surfactant includes the structure of formula (IA): wherein R1 includes the structure of formula (IIA), (IIIA), or (IVA), wherein X includes an integer ranging from approximately 0 to approximately 20, wherein R2 comprises a linear or branched aliphatic group containing approximately 8 to approximately 25 carbon atoms, and wherein R3 comprises an aliphatic or aromatic group containing approximately 1 to approximately 20 carbon atoms and at least one —N═C═S group.
