An antimicrobial hand wash comprises an active ingredient and an amphoteric surfactant that is a derivative compound of a fatty amine with a nitrogen atom bound to at least one, but not greater than two, propionic acids. These specific amphoteric surfactants hav e unexpectedly been found to be compatible with active ingredients such that the antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Othe r antimicrobial hand washes include polyethylene glycol or polypropylene glycol derivatives that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in th e formulation, and making a cold manufacturing process possible.
