HYPOCHLOROUS ACID-BASED HAND SANITIZER
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.
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.
