Abstract
The invention provides antimicrobial compositions comprising one or more acid and one or more organic diol. In one embodiment, the invention'"'"'s compositions have an acidic pH. The compositions may optionally further contain one or more oxidizing agent (including stabilized oxidizing agent and/or unstabilized oxidizing agent), and/or one or more surfactant. In particular embodiments, the acid lacks one or both of —NH group and —NH2 group. The invention'"'"'s compositions are useful in all stages of handling agricultural products, in hospitals, and in commercial and household applications.
