Abstract
Anti-microbial Formulations and methods of their use and production are disclosed. The Formulations of the present invention are effective as broad spectrum anti-bacterial agents with efficacy against both Gram-negative and Gram-positive bacteria, as anti-viral agents with efficacy against both enveloped and non-enveloped viruses, anti fungal agents and anti spore forming agents. The present invention includes anti-microbial Formulations that include at least one surfactant, optionally at least one acid, at least one non-cationic anti-microbial agent, and optionally water. The anti-microbial Formulations of the present invention may additionally contain an organic salt. The organic salt may be a salt of the same acid that is used in the Formulation or a salt of a different acid.
