Abstract
The disclosure provides compositions and methods for making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The compositions and methods described here allow an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.
Claims20
A colored aqueous solution of 0.1-2% sodium hypochlorite or calcium hypochlorite comprising
- at least one oxidizable water-soluble pigment,
- a surfactant selected from the group consisting of sodium dodecyl sulfate (SDS), sodium xylene sulfonate (SXS), sodium laureth sulfate (SLES), sodium myreth sulfate (SMS), sodium cholate, an acetylenic diol, alkyldiphenyloxide disulfonate, and sodium toluene sulfonate (STS), and mixtures thereof,
- an alkaline builder selected from the group consisting of sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2), potassium hydroxide (KOH), and lithium hydroxide (LiOH), and mixtures thereof, and
- an optional rheology modifier selected from the group consisting of sodium alginate, glycerol, guar gum, dextran, cellulose, carrageenan (lambda, iota, kappa), sodium carbonate, fumed silica, alkali swellable emulsions, hydrophobically modified alkali swellable emulsions, hydrophobically-modified polyurethanes, and sodium polyacrylate, and mixtures thereof,
- wherein the color is stable in the colored aqueous solution of 0.1-2% sodium hypochlorite or calcium hypochlorite for from 10 to 20 minutes and fades to clear when the solution is applied as a spray or film to a surface.
