Additive compositions for pigmented disinfection and methods thereof
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.
1. A solid composition comprising particles comprising:
a surfactant, wherein the surfactant is sodium dodecyl sulfate,
a water-soluble pigment,
a thickening agent,
an alkaline builder selected from sodium hydroxide and potassium hydroxide, and
a hydrotrope selected from sodium p-toluenesulfonate, potassium toluene-4-sulphonate, sodium xylenesulfonate, potassium xylenesulphonate, and sodium cumenesulfonate.
2. The composition of claim 1 , wherein the alkaline builder is sodium hydroxide; and the composition further comprises an oxidizing agent selected from sodium nitrite, potassium nitrate, and sodium iodate.
3. The composition of claim 1 , wherein the hydrotrope is sodium p-toluenesulfonate; and the composition further comprises reducing agent selected from ascorbic acid, sodium ascorbate, and glutathione.
4. The composition of claim 1 , wherein the thickening agent is-selected from sodium alginate, glycerol, guar gum, dextran, and cellulose.
5. The composition of claim 1 , wherein the pigment 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, chlorophyllin, caramel coloring, butterfly pea, pandan, ultramarine, cobalt blue, phthalocyanine, and Coomassie Brilliant Blue.
6. A method for increasing the visibility of a liquid disinfectant applied to a surface as a spray or film, comprising:
mixing an amount of the composition of claim 1 with the liquid disinfectant and applying the liquid disinfectant to the surface as a spray or film,
wherein the amount of the composition of claim 1 is sufficient to color the liquid disinfectant, and
wherein after application to the surface, the color of the liquid disinfectant fades within a period of time of from 3 to 10 minutes.
7. The method of claim 6 , wherein the liquid disinfectant is an aqueous bleach solution.
8. The method of claim 6 , wherein the liquid disinfectant comprises one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride.
9. A method for disinfecting a surface or an object, comprising: mixing an amount of the composition of claim 1 with a liquid disinfectant and applying the liquid disinfectant to the surfaces or the object as a spray or film according to the method of claim 6 .
10. A solid composition, comprising particles of:
a surfactant selected from sodium dodecylbenzenesulfonate, hexadecyltrimethylammonium bromide, and sodium 3,4-dichlorobenzoate,
a water-soluble pigment,
a thickening agent,
an alkaline builder selected from sodium hydroxide and potassium hydroxide, and
a hydrotrope selected from sodium p-toluenesulfonate, potassium toluene-4-sulphonate, sodium xylenesulfonate, potassium xylenesulphonate, and sodium cumenesulfonate.
11. The composition of claim 10 , wherein the alkaline builder is sodium hydroxide; and the composition further comprises an oxidizing agent selected from sodium nitrite, potassium nitrate, and sodium iodate.
12. The composition of claim 10 , wherein the hydrotrope is sodium p-toluenesulfonate; and the composition further comprises reducing agent selected from ascorbic acid, sodium ascorbate, and glutathione.
13. The composition of claim 10 , wherein the thickening agent is-selected from sodium alginate, glycerol, guar gum, dextran, and cellulose.
14. The composition of claim 10 , wherein the pigment 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, chlorophyllin, caramel coloring, butterfly pea, pandan, ultramarine, cobalt blue, phthalocyanine, and Coomassie Brilliant Blue.
15. A method for increasing the visibility of a liquid disinfectant applied to a surface as a spray or film, comprising:
mixing an amount of the composition of claim 10 with the liquid disinfectant and applying the liquid disinfectant to the surface as a spray or film,
wherein the amount of the composition of claim 10 is sufficient to color the liquid disinfectant, and
wherein after application to the surface, the color of the liquid disinfectant fades within a period of time of from 3 to 10 minutes.
16. The method of claim 15 , wherein the liquid disinfectant is an aqueous bleach solution.
17. The method of claim 15 , wherein the liquid disinfectant comprises one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride.
18. A method for disinfecting a surface or an object, comprising: mixing an amount of the composition of claim 10 with a liquid disinfectant and applying the liquid disinfectant to the surfaces or the object as a spray or film according to the method of claim 15 .
