## Abstract

The invention provides to a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

## Claims

### Claim 1

A method for disinfecting a surface or an object, the method comprising (i) providing a colored disinfection solution comprising one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride; a surfactant; and a colorant; wherein the colorant is sufficient to color the disinfectant solution; and
(ii) applying the colored disinfectant solution as a spray or film to the surface or object in need of disinfection;
wherein the color of the disinfectant solution clearly marks where the disinfectant solution has or has not been applied and the color of the disinfectant solution fades to clear within a period of time.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the period of time is from 3 to 30 minutes.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the period of time is for up to 15 minutes.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the disinfectant solution is an aqueous bleach solution.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the surfactant is selected from sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, hexadecyltrimethylammonium bromide, and sodium 3,4-dichlorobenzoate.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the composition further comprises a thickening agent.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the composition further comprising a hydrotrope.

### Claim 8 (depends on 6)

The method according to claim 6, wherein the thickening agent is selected from sodium alginate, glycerol, guar gum, dextran, and cellulose.

### Claim 9 (depends on 7)

The method according to claim 7, wherein the hydrotrope is selected from sodium p-toluenesulfonate, potassium toluene-4-sulphonate, sodium xylenesulfonate, potassium xylenesulphonate, and sodium cumenesulfonate.

### Claim 10 (depends on 1)

The method according to claim 1, wherein the composition further comprises an alkaline builder.

### Claim 11 (depends on 10)

The method according to claim 10, wherein the alkaline builder is selected from sodium hydroxide and potassium hydroxide.

### Claim 13

A method for increasing the visibility of a disinfectant solution applied to a surface or an object, the method comprising
(i) providing a disinfection solution comprising one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride; a surfactant; and a colorant; wherein the colorant is sufficient to color the disinfectant solution; and
(ii) applying the colored disinfectant solution as a spray or film to the surface or object in need of disinfection;
wherein the color of the disinfectant solution clearly marks where the disinfectant solution has or has not been applied and the color of the disinfectant solution fades to clear within a period of time.

### Claim 18 (depends on 13)

The method according to claim 13, wherein the composition further comprises a thickening agent.

### Claim 19 (depends on 13)

The method according to claim 13, wherein the composition further comprising a hydrotrope.

### Claim 20 (depends on 18)

The method according to claim 18, wherein the thickening agent is selected from sodium alginate, glycerol, guar gum, dextran, and cellulose.

### Claim 21 (depends on 19)

The method according to claim 19, wherein the hydrotrope is selected from sodium p-toluenesulfonate, potassium toluene-4-sulphonate, sodium xylenesulfonate, potassium xylenesulphonate, and sodium cumenesulfonate.

### Claim 22 (depends on 13)

The method according to claim 13, wherein the composition further comprises an alkaline builder.

### Claim 23 (depends on 22)

The method according to claim 22, wherein the alkaline builder is selected from sodium hydroxide and potassium hydroxide.

### Claim 24 (depends on 13)

The method according to claim 13, wherein the colorant is selected from one or more of FD&C Blue #1, fast green FCF, erythrosine, allura red AC, tartrazine, sunset yellow FCF, indigo carmine, betanin, caramel coloring, butterfly pea, and Coomassie Brilliant Blue.

### Claim 25

A colored disinfectant composition, consisting of one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride, a surfactant, a colorant, a thickening agent, and a hydrotrope.
