Chloroxylenol is bactericidal against most gram positive bacteria. Triclosan blocks the active site of an enzyme called enoyl-acyl carrier-protein reductase (ENR), preventing the bacteria from manufacturing fatty acids it needs for building cell membranes and other vital functions. Humans don't have this enzyme, so triclosan is harmless to them. One molecule of triclosan permanently disables an ENR molecule, which explains why triclosan has powerful antibiotic action even at very low concentrations. Triclocarban (TCC), or 3,4,4'-trichlorocarbanilide, is a substance with anti-bacterial and anti-fungal properties. The mechanism of action involves disruption of cellular membranes, and the chemical may also involve inhibition of the enzyme enoyl-acyl carrier protein reductase (ENR). This enzyme is absent in humans but is essential in building cell membranes of many bacteria and fungi.

Rarely, sensitivity to one of the ingredients may cause irritation of the skin. If this happens you should wash with lukewarm water and stop using the product.
