Abstract
A composition for use in disinfecting a surface for personal use, such as a public restroom facility or telephone. The composition and delivery of the composition provides for the placement of a thin layer of disinfectant which includes a dye. The dye disappears as the thin layer effects the germicidal activity of the disinfectant. The composition is also rapidly drying, so that the dye disappears as well as the disinfecting composition leaving the surface dry.
Claims5
A biocide composition for disinfecting a surface for personal use consisting essentially of:
- a germicide;
- a small amount of surfactant;
- a pH sensitive dye which changes color upon exposure to air;
- an alkali means for adjusting the pH of the composition to produce a color in the liquid with the dye so that upon neutralization the dye loses color;
- said biocide being a visually colored germicide composition with the disappearing pH sensitive dye effectively indicating the delivery of the germicide and giving a visual check as to the area disinfected when the visually colored compound is applied;
- and
- said biocide composition is packaged sealed airtight.
A biocide composition for disinfecting a surface for personal use comprising:
- a lower alkyl alcohol having 1 to 4 carbon atoms;
- a surfactant selected from the group consisting essentially of sodium dodecyl sulfate, octyl phenoxy polyethoxyethanol, triethanol amine lauryl sulfate and mixtures thereof;
- the pH sensitive dye thymolphthalien which changes color upon exposure to air;
- an alkali means for adjusting the pH of the composition to produce a color in the liquid with the dye so that upon neutralization the dye loses color;
- said biocide being a visually colored germicide composition with the disappearing pH sensitive dye effectively indicating the delivery of the germicide and giving a visual check as to the area disinfected when the visually colored compound is applied;
- and
- said biocide composition is packaged sealed airtight.
