Abstract

The present invention generally relates to anti-microbial formulations and methods of their use and production. 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, and as anti-fungal agents with efficacy against both vegetative and spore forms of microorganisms and against biofilms. The present invention includes anti-microbial compositions that have at least one surfactant, at least one acid, at least one peroxide (preferably hydrogen peroxide), peracetic acid, and 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. Methods for production and use of the inventive compositions are disclosed.
