Hypochlorous acid-based hand sanitizer

Abstract

A sanitizing formulation is disclosed for use as a hand sanitizer. The formulation may include hypochlorous acid, a silicone polymer or blend thereof, sodium phosphate, hydrochloric acid, and sodium magnesium silicate. Methods of using and making the sanitizing formulation are also disclosed.

What is claimed is: 
     
         1 . A method of disinfecting a surface, comprising:
 applying to the surface a sanitizing formulation comprising hypochlorite.   
     
     
         2 . The method of  claim 1 , wherein the surface is skin. 
     
     
         3 . The method of  claim 1 , wherein the sanitizing formulation further comprises at least one of sodium phosphate or hydrochloric acid, sodium magnesium silicate, and a silicone polymer or blend thereof. 
     
     
         4 . The method of  claim 3 , wherein hypochlorite is in an amount of about 75 ppm, wherein the sodium phosphate is in an amount of about 0.2% w/v, wherein the hydrochloric acid is in an amount of about 0.08% w/v, wherein the sodium magnesium silicate is in an amount of about 3% w/v, and wherein the silicone polymer or blend thereof is in an amount of about 3% w/v. 
     
     
         5 . The method of  claim 1 , wherein the sanitizing formulation further comprises water, buffer, or combinations thereof. 
     
     
         6 . The method of  claim 1 , wherein the applying comprises killing at least one superbug. 
     
     
         7 . The method of  claim 6 , wherein the at least one superbug is selected from the group consisting of  Staphylococcus aureus  (including methicillin-resistant  S. aureus  (MRSA) and vancomycin-resistant  S. aureus  (VRSA)), extended spectrum beta-lactamase (ESBL),  Pseudomonas aeruginosa, Clostridium difficile, Salmonella, Mycobacterium tuberculosis, Escherichia coli  (including Carbapenem resistant  E. coli ), multidrug-resistant  Acinetobacter baumannii  (MRAB), vancomycin-resistant  Enterococcus  (VRE), Carbapenem resistant  Klebsiella pneumoniae,  HIV, hepatitis, and influenza. 
     
     
         8 . A sanitizing formulation, comprising:
 hypochlorous acid;   sodium phosphate or hydrochloric acid;   sodium magnesium silicate; and   a silicone polymer or blend thereof.   
     
     
         9 . The formulation of  claim 8 , wherein the hypochlorous acid is present in an amount of about 50 to about 200 ppm. 
     
     
         10 . The formulation of  claim 8 , wherein the sodium phosphate is present in an amount of about 0.1 to about 0.5% w/v. 
     
     
         11 . The formulation of  claim 8 , wherein the hydrochloric acid is present in an amount of about 0.01% to about 15% w/v. 
     
     
         12 . The formulation of  claim 8 , wherein the sodium magnesium silicate is present in an amount of 0 to about 5% w/v. 
     
     
         13 . The formulation of  claim 8 , wherein the silicone polymer or blend thereof comprises a blend of dimethicone and cyclomethicone. 
     
     
         14 . The formulation of  claim 8 , wherein the silicone polymer or blend thereof is present in an amount of about 1 to about 20% w/v. 
     
     
         15 . The formulation of  claim 8 , wherein the hypochlorous acid is in an amount of about 75 ppm, wherein the sodium phosphate is in an amount of about 0.2% w/v, wherein the sodium magnesium silicate is in an amount of about 3% w/v, and wherein the silicone polymer or blend thereof is in an amount of about 3% w/v. 
     
     
         16 . The formulation of  claim 8 , wherein the hypochlorous acid is in an amount of about 75 ppm, wherein the hydrochloric acid is in an amount of about 0.08% w/v, wherein the sodium magnesium silicate is in an amount of about 3% w/v, and wherein the silicone polymer or blend thereof is in an amount of about 3% w/v. 
     
     
         17 . The formulation of  claim 8 , wherein the pH is in the range from 6.5-7.8. 
     
     
         18 . The formulation of  claim 8 , further comprising water, buffer, or combinations thereof.
