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 have 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. Other 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 the formulation, and making a cold manufacturing process possible.
