## Abstract

This disclosure relates to anti-microbial sanitizer compositions and methods of making the same. The sanitizer compositions described herein are comprised of benzalkonium chloride, coconut oil, palm kernel oil, water, dihydroxypropyl PEG-5, linoleammonium chloride, and glycereth-2 cocoate. To forming the sanitizer compositions discussed herein, water is mixed with benzalkonium chloride to form a first mixture. This first mixture is then mixed with coconut oil and palm kernel oil to form a second mixture, which is subsequently heated to at least 100° F. After heating, the second mixture is mixed with dihydroxypropyl PEG-5 to form a third mixture, which is then settled while the temperature is maintained at or above 100° F., Thereafter, the third mixture is cooled to room temperature, and mixed with linoleammonium chloride and glycereth-2 cocoate to form the sanitizer composition.

## Claims

### Claim 1

A method of making a sanitizer composition, comprising:
directing water to a tank;
mixing benzalkonium chloride with the water in the tank to form a first mixture;
mixing coconut oil and palm kernel oil with the first mixture to form a second mixture;
heating the second mixture to at least 100° F.;
after heating the second mixture, mixing dihydroxypropyl PEG-5 with the second mixture to form a third mixture;
settling the third while maintaining the temperature at or above 100° F.;
after settling the third mixture, cooling the third mixture to room temperature;
mixing linoleammonium chloride to the third mixture to form a fourth mixture; and
mixing glycereth-2 cocoate to the fourth mixture to form a sanitizer composition.

### Claim 2 (depends on 1)

The method of claim 1, further comprising determining the amount of benzalkonium chloride, water, palm kernel oil, coconut oil, dihydroxypropyl PEG-5, linoleammonium chloride, and glycereth-2 cocoate necessary to make a sanitizer composition wherein the sanitizer composition comprises 1.0% benzalkonium chloride, 0.30% coconut oil, 0.20% palm kernel oil, 98.67% water, 0.050% dihydroxypropyl PEG-5, 0.020% linoleammonium chloride, and 0.030% glycereth-2 cocoate by weight percent.

### Claim 3 (depends on 1)

The method of claim 1, wherein the tank is a heated jacket tank.

### Claim 4 (depends on 1)

The method of claim 1, wherein the tank includes a high speed mixer.

### Claim 5 (depends on 4)

The method of claim 4, wherein the mixer is a shear mixer.

### Claim 6 (depends on 4)

The method of claim 4, wherein the mixer is capable of reducing particle size to
particles with an average diameter of 1 micron.

### Claim 7 (depends on 1)

The method of claim 1, wherein mixing the benzalkonium chloride with the water occurs for a period of at least five minutes.

### Claim 8 (depends on 1)

The method of claim 1, wherein mixing coconut oil and palm kernel oil with the first mixture occurs for a period of 30 minutes.

### Claim 9 (depends on 1)

The method of claim 1, wherein the second mixture is heated to a temperature between 120° F. and 130° F.

### Claim 10 (depends on 1)

The method of claim 1, wherein cooling the third mixture to room temperature occurs over a period of twenty four hours.

### Claim 11 (depends on 1)

The method of claim 1, further comprising diluting the sanitizes composition to form a diluted composition.

### Claim 12 (depends on 11)

The method of claim 11, wherein the benzalkonium chloride comprises 0.10 weight percent of the diluted composition.

### Claim 13

A method of forming a sanitizer composition, the method comprising:
determining the amount of benzalkonium chloride, water, palm kernel oil, coconut oil, dihydroxypropyl PEG-5, linoleammonium chloride, and glycereth-2 cocoate necessary to make a sanitizer composition wherein the sanitizer composition comprises 1.0% benzalkonium chloride, 0.30% coconut oil, 0.20% palm kernel oil, 98.67% water, 0.050% dihydroxypropyl PEG-5, 0.020% linoleammonium chloride, and 0.030% glycereth-2 cocoate by weight percent;
directing the determined amount of water into a tank, wherein the tank includes a high speed shear mixer, and wherein the mixer is capable of shearing particles such that the average particle diameter after mixing is less than or equal to 1 micron;
mixing the water with the determined amount of benzalkonium chloride for at least five minutes to form a first mixture;
mixing the determined amount of palm kernel oil and the determined amount of coconut oil with the first mixture for at least thirty minutes to form a second mixture;
heating the second mixture to at least 100° F.;
mixing the determined amount of dihydroxypropyl PEG-5 with the second mixture at a temperature at or above 100° F. to form a third mixture;
settling the third mixture for one hour while maintaining the temperature of the third mixture at or above 100° F.;
reducing the temperature of the third mixture to room temperature while continuing to settle the third mixture for twenty four hours;
mixing the determined amount of linoleammonium chloride with the third mixture for at least thirty minutes to form a fourth mixture; and
mixing the determined amount of glycereth-2 cocoate with the fourth mixture to form the sanitizer composition.

### Claim 14 (depends on 13)

The method of claim 13, further comprising diluting the sanitizer composition to form a diluted composition such that the benzalkonium chloride comprises 0.10 weight percent of the diluted composition.
