Abstract

Antimicrobial compositions providing synergistic antimicrobial effects against a variety of bacterial, viral and fungal organisms are described. Methods for using the antimicrobial compositions and products containing the antimicrobial compositions are also described herein.

         17 . A method of protecting a surface against exposure to pathogenic microorganisms, the method comprising applying a disinfectant product to a surface, the disinfectant product comprising an antimicrobial composition comprising:
 a) ethylenediamine tetraacetic acid (EDTA) or salts thereof;   b) a straight chain 1,2-alkanediol, wherein the straight chain 1,2-alkanediol is selected from the group consisting of 1,2-pentanediol or 1,2-hexanediol;   c) a surfactant;   d) a biocidal terpenoid; and   e) the balance being water; and   
       wherein the composition has an immediate effectiveness and prolonged persistence against a pathogenic microorganism such that the composition is at least 99.9999% effective against a pathogenic microorganism after 10 minutes of exposure and remains at least 99.9999% effective against the pathogenic microorganism for 5 days or longer. 
     
     
         18 . The method of  claim 17 , wherein the pathogenic microorganism is a bacteria, virus or fungi. 
     
     
         19 . The method of  claim 18 , wherein the composition exhibits antimicrobial and bactericidal efficacy against the pathogenic microorganism. 
     
     
         20 . The method of  claim 18 , wherein the pathogenic microorganism is a bacteria, wherein the bacteria is  Staphylococcus aureus.    
     
     
         21 . The method of  claim 17 , wherein the composition remains at least 99.9999% effective against the pathogenic microorganism for up to 12 days after being applied to the surface. 
     
     
         22 . The method of  claim 17 , wherein the composition comprises from about 0.2% to about 3%, by weight per volume, of EDTA. 
     
     
         23 . The method of  claim 17 , wherein the composition comprises from about 1% to about 5%, by volume per volume, of the straight chain 1,2-alkanediol. 
     
     
         24 . The method of  claim 17 , wherein the composition comprises from about 0.01% to about 2%, by weight per volume, of the surfactant. 
     
     
         25 . The method of  claim 17 , wherein surfactant is sodium dodecyl sulfate. 
     
     
         26 . The method of  claim 17 , wherein the composition from about 0.05% to about 0.5%, by weight per volume, of the biocidal terpenoid. 
     
     
         27 . The method of  claim 17 , wherein the biocidal terpenoid is selected from the group consisting of thymol, carvacrol, eugenol, and limonene.
