Abstract

Compositions comprising silver dihydrogen citrate in combination with a second antimicrobial compound are provided. The second antimicrobial compound may be quaternary ammonia, an oxidizer or a halogen species, such as chlorine, bromine or iodine. Methods of using the antimicrobial composition provide superior antimicrobial effects.

Claims

exact text as granted — not AI-modified
1 . A composition comprising silver dihydrogen citrate, citric acid and a second antimicrobial agent selected from the group consisting of a quaternary ammonium compound, an oxidizing agent and a halogen compound.  
     
     
         2 . The composition of  claim 1 , wherein the second antimicrobial agent is quaternary ammonia.  
     
     
         3 . The composition of  claim 1 , wherein the second antimicrobial agent is an oxidizer.  
     
     
         4 . The composition of  claim 3 , wherein the oxidizer is selected from hydrogen peroxide, potassium monopersulfate and potassium permanganate.  
     
     
         5 . The composition of  claim 1 , wherein the second antimicrobial agent is a halogen compound.  
     
     
         6 . The composition of  claim 5 , wherein the halogen is chlorine, a hypochlorite, bromine or iodine.  
     
     
         7 . The composition of  claim 1 , further comprising a dispersing agent.  
     
     
         8 . The composition of  claim 7 , wherein the dispersing agent is a detergent.  
     
     
         9 . The composition of  claim 8 , wherein the detergent is sodium dodecyl sulfate or Octoxynol.  
     
     
         10 . A method of using the composition of  claim 1 , comprising applying the composition to a substrate, whereby an antimicrobial effect is achieved.  
     
     
         11 . The method of  claim 10 , wherein the substrate is a solid surface.  
     
     
         12 . The method of  claim 10 , wherein the substrate is a fabric.  
     
     
         13 . The method of  claim 10 , wherein the substrate is an article.  
     
     
         14 . The method of  claim 10 , wherein the antimicrobial effect is a bacteriocidal effect.  
     
     
         15 . The method of  claim 10 , wherein the antimicrobial effect is bacteriostasis.  
     
     
         16 . The method of  claim 10 , wherein the antimicrobial effect is a virucidal effect.  
     
     
         17 . The method of  claim 10 , wherein the antimicrobial effect is a fungicidal effect.
