## Abstract

An aqueous disinfecting solution and uses and methods of disinfection and sanitization employing same. The solution comprises at least one inorganic salt selected from the group consisting of sulfate, chloride, bromide, iodide, carbonate, phosphate, fluoride, and nitrate salts in a concentration of from about 0.1 to about 15 wt. %; at least one peroxide compound in a concentration of from about 0.01 to about 8 wt. %; and at least one amphoteric amine oxide surfactant having the formula R1R2R3NO wherein each of R1, R2, and R3 is independently a saturated, unsaturated, substituted or unsubstituted linear or branched alkyl group having from 1 to 28 carbon atoms in a concentration of from about 0.01 to about 15 wt. %.

## Claims

### Claim 1

A disinfecting solution comprising:
at least one inorganic salt chosen from sodium chloride, ammonium sulfate, sodium sulfate, sodium phosphate in an amount of from about 0.5 wt % to about 8 wt %;
hydrogen peroxide in an amount of from about 0.5 wt % to about 3 wt %;
lauramine oxide in an amount of from about 0.5 wt % to about 8 wt %; and
water;
wherein the pH is from about 1.5 to about 4.

### Claim 2 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfecting solution further comprises at least one pH adjusting agent.

### Claim 3 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfecting solution further comprises at least one amphoteric surfactant.

### Claim 4 (depends on 3)

The disinfecting solution of claim 3, wherein the at least one amphoteric surfactant is cocarnidopropyl betaine.

### Claim 5 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfect solution further comprises at least one solvent.

### Claim 6 (depends on 5)

The disinfecting solution of claim 5, wherein the at least one solvent is selected from the group consisting of phenethyl alcohol, benzyl alcohol, phenoxyethanol, and cyclopentylmethanol.

### Claim 7 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfecting solution further comprises at least one of salicylic acid, benzoic acid and 2-furoic acid.

### Claim 8 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfecting solution further comprises skin conditioning agent.

### Claim 9 (depends on 8)

The disinfecting solution of claim 8, wherein the skin conditioning agent comprises glycerin, poly-glycerin, butylene glycol, or any mixture thereof.

### Claim 10 (depends on 1)

The disinfecting solution of claim 1, wherein the disinfecting solution further comprises at least one additive chosen from buffering agents, dyes, fragrances, rheology modifiers, corrosion inhibitors, peroxide stabilizing agents, hydrotropes, non-ionic surfactants, cationic surfactants, soil suspenders or anti- redeposition agents, or additional antimicrobial agents.

### Claim 11 (depends on 1)

A diluted disinfecting solution, obtained by diluting the disinfecting solution of claim 1.

### Claim 12 (depends on 1)

A concentrated disinfecting solution, wherein upon dilution provides the disinfecting solution of claim 1.

### Claim 13

The disinfecting solution of 1, for use in disinfection or sanitization.

### Claim 14 (depends on 1)

The disinfecting solution of claim 1, effective to increase the reduction of microorganisms by at least 1 log when the at least one inorganic salt is present, as compared to when the at least one inorganic salt is absent, using the EN 1276 test method against E. hirae at a contact time of 30 or 60 seconds.

### Claim 15 (depends on 1)

A method of disinfecting or sanitizing a surface comprising applying an effective amount of the solution of claim 1 to the surface for a contact time of at least 10 seconds.
