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.
Claims18
A solid composition comprising
- at least one water-soluble pigment in an amount of from 1.5-22% w/w, based on the total weight of the composition,
- at least one surfactant in an amount of from 10-75% w/w, based on total weight of the composition, the surfactant selected from the group consisting of sodium dodecyl sulfate (SDS), sodium xylene sulfonate (SXS), and mixtures thereof,
- an alkaline builder in an amount of from 2-50% w/w, based on the total weight of the composition, the alkaline builder selected from NaOH and Ca(OH)2, and mixtures thereof, and
- a rheology modifier in an amount of from 10-65% w/w, based on the total weight of the composition, wherein the rheology modifier is lambda carrageenan.
