Disinfectant Formulation Comprising Calcium Hydroxide and Sodium Hypochlorite

Abstract

The application relates to disinfectant formulations comprising calcium hydroxide and sodium hypochlorite and further relates to a method of manufacturing the disinfectant formulations and methods of disinfecting an object using the disinfectant formulations.

1 . A disinfectant formulation comprising calcium hydroxide (Ca(OH) 2 ) and sodium hypochlorite (NaClO). 
     
     
         2 . The disinfectant formulation of  claim 1  wherein the formulation is an aqueous formulation having about 0.12% to about 0.18% by volume calcium hydroxide and about 0.1 to about 5% by volume sodium hypochlorite. 
     
     
         3 . The disinfectant formulation according to  claim 2  wherein the sodium hypochlorite is about 0.1% to about 0.3% by volume. 
     
     
         4 . The disinfectant formulation according to  claim 3  wherein the sodium hypochlorite is about 0.125% to about 2.5% by volume. 
     
     
         5 . The disinfectant formulation according to  claim 4  wherein the sodium hypochlorite is about 0.125% by volume. 
     
     
         6 . A method of manufacturing a disinfectant formulation as defined in  claim 1  comprising:
 a) mixing calcium hydroxide dry powder with water in a percentage ratio of about 2.5 to about 97.5 by weight to form a supernatant solution of calcium hydroxide in water having a dissolved solids concentration of about 0.12% to about 0.18% and 
 b) adding sodium hypochlorite in an amount to achieve a solution concentration of from about 0.1% to 5% by volume. 
 
     
     
         7 . The method of  claim 6  wherein the solids concentration of the calcium hydroxide in the supernatant solution is controlled by adjusting the temperature. 
     
     
         8 . The method of  claim 6  wherein the dry powder Ca(OH) 2  is 97% pure and 200 mesh size and the water is deionized. 
     
     
         9 . A method of disinfecting an object comprising applying a disinfectant formulation as defined in  claim 1  to an object to be disinfected. 
     
     
         10 . The method of disinfecting an object according to  claim 9  whereby microorganisms on the object are destroyed and the micro-organisms are one or more of bacteria, fungus, mold and viruses.
