Compositions and methods for multipurpose disinfection and sterilization solutions

Abstract

The present disclosure discloses compositions and methods for multipurpose disinfection and sterilization solutions broadly effective against multiple microbial pathogens. The present disclosure demonstrates broad spectrum antimicrobial activity against environmental and pathogenic amoeba, bacterial spores, vegetative bacteria, fungi, rickettsia, viruses, parasites and toxic microbial products. The multipurpose disinfection solutions of the present disclosure may be used alone or in combination for a variety of purposes, including disinfection of medical devices such as contact lenses, contact lens cases, surgical instruments, and dental instruments.

1 . A medical disinfecting composition comprising:
 (a) a chlorite salt;   (b) a quaternary ammonium salt, wherein the quaternary ammonium salt is C12-C14-alkyl(ethylbenzyl)dimethylammonium chloride;   (c) ammonium chloride having a formula of NH 4 Cl; and   (d) water.   
     
     
         2 . The medical disinfecting composition of  claim 1 , wherein the chlorite salt is an alkali metal chlorite salt. 
     
     
         3 . The medical disinfecting composition of  claim 2 , wherein the alkali metal chlorite salt is sodium chlorite. 
     
     
         4 . The medical disinfecting composition of  claim 3 , wherein the sodium chlorite is present in an amount ranging from about 0.0001% to about 0.1% (w/w). 
     
     
         5 . The medical disinfecting composition of  claim 3 , wherein the sodium chlorite is provided as a stabilized chlorine dioxide solution. 
     
     
         6 . The medical disinfecting composition of  claim 5 , wherein the stabilized chlorine dioxide is present in an amount ranging from about 0.005% to about 1.0% (w/w). 
     
     
         7 . The medical disinfecting composition of  claim 5 , wherein the stabilized chlorine dioxide solution comprises chlorine dioxide.
