Various embodiments provide an antimicrobial composition comprising: a safe and effective amount of benzoic acid analog or analogs; a safe and effective amount of a buffer system of weak organic acids buffer with the negative log of the acid dissociation constant, pKa, between about 3.2 and 4.9; and a dermatologically acceptable carrier for the benzoic acid analogs and weak organic acid buffers, wherein the antimicrobial composition has a pH from about 3.2 to 4.9. In some embodiments, the antimicrobial composition comprises a safe and effective amount of an antimicrobial metal ion salt, a preferred salt being copper gluconate, at a level and pH that does not precipitate with the weak acid buffers.
