Embodiment 1

[0058] Example 1: Closed system electrospray distribution and log-kill study

[0059] A study according to an embodiment of the present disclosure was conducted to determine the antimicrobial effect of a method in which iodine was formed in situ on a target surface within a 1 cubic meter translucent plastic cube by applying two separate aqueous compositions Biocide, two separate aqueous compositions, one comprising potassium iodide and one comprising hydrogen peroxide. In approximate amounts, include the following ingredients:

[0060] First aqueous composition:

[0061] 0.64% (w / w) potassium iodide

[0062] 15% (w / w) ethanol

[0063] 0.003% (w / w) cinnamon oil

[0064] 84.357% (w / w) distilled water

[0065] Second aqueous composition:

[0066] 5.25% (w / w) hydrogen peroxide

[0067] 15% (w / w) ethanol

[0068] 79.75% (w / w) distilled water

[0069] To simultaneously assess whether an electrospray device will uniformly distribute an aqueous composition including an iodine...

Embodiment II

[0090] Example II: 15 Petri dishes comprising nutrient agar were streaked with Bacillus subtilis in three areas in a conventional manner. After streaking (control), 5 petri dishes were sealed. Five petri dishes were sprayed with a solution comprising 2 ppm KI and 10% ethanol sufficient to wet the surface, and then sealed. And, as before, 5 Petri dishes were first sprayed, then sprayed with a solution comprising 5% hydrogen peroxide and 2.5% isopropanol, and then sealed.

[0091] After incubating all 15 dishes at 40°C for 3 days, the number of colony forming units was estimated as follows: ~10k for the control; ~6k for the KI control, and "0" for the double spray test.

Abstract

This disclosure provides a method of disinfecting a surface within an area, comprising the steps of: a) dispersing into the area a multiplicity of droplets of a first aqueous composition comprising afirst iodine reactant compound that is either a peroxide compound or an iodine salt compound: b) allowing sufficient time for the first aqueous composition to distribute throughout the area, and to deposit and coalesce into a layer upon the surface: c) dispersing into the area a multiplicity of droplets of a second aqueous composition comprising a second iodine reactant compound that is the otherof the first iodine reactant compound, and: d) again allowing sufficient time for the droplets of the second aqueous composition to deposit onto the coalesced layer of the first aqueous composition, thereby forming iodine and other iodine biocides in situ and disinfecting the surface.

Description

[0001] Cross references to related applications: [0002] This application claims priority to Provisional Patent Application No. 62 / 591,812, filed November 29, 2017. technical field [0003] The present invention is in the field of disinfection and sterilization methods. Background technique [0004] There is a need for an inexpensive, effective, safe and convenient way to minimize the microbial load of objects with which we interact. This approach in no way renders microorganisms resistant to future treatments. And, as microorganisms resistant to nearly all known antibiotics become more common, the need is becoming more acute. [0005] What we need is a way to kill nearly all microorganisms in such a way that they cannot develop resistance to antimicrobial agents. A possible way of doing this is by utilizing ingredients and methods that are relatively safe for humans but are biocidal. [0006] Iodine is a well-known, relatively safe biocide, and hydrogen peroxide has re...
