Additive compositions for pigmented disinfection and methods thereof
The invention provides 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 of:
a surfactant selected from sodium dodecyl sulfate, 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.
2. The composition of claim 1 , wherein
the pigment is FD&C Blue #1; and
the surfactant is sodium dodecyl sulfate.
3. 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.
4. 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.
5. The composition of claim 4 , comprising FD&C Blue #1; sodium dodecyl sulfate;
sodium p-toluenesulfonate; sodium hydroxide; sodium nitrite; and ascorbic acid.
6. The composition of claim 1 , wherein the thickening agent is-selected from sodium alginate, glycerol, guar gum, dextran, and cellulose.
7. 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.
8. A packet comprising the composition of claim 1 .
9. 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.
10. The method of claim 9 , wherein the liquid disinfectant is an aqueous bleach solution.
11. The method of claim 9 , wherein the liquid disinfectant comprises one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid, and benzalkonium chloride.
12. The method of claim 9 , wherein the liquid disinfectant has a pH of about 3 to 12.
13. The method of claim 9 , wherein the liquid disinfectant has a pH of about 5 to 10.
14. 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 9 .
