Abstract

There is provided a soap that contains an indicator that produces an observable change after a period of time to show that sufficient cleaning has been done or to indicate the thoroughness of the cleaning. The soap is preferably made from two components that produce a color and/or viscosity changes after about 30 seconds of use. This use indicating change is useful for, for example, teaching children to was their hands for a sufficient period of time.

Claims

1. A cleaning aid comprising a composition of a first component comprising a soap and a dye and a second component comprising ascorbic acid and iron chloride with said first component and said second component being separated from each other, wherein, upon dispensing said composition, said first component and said second component mix and react to produce an observable indicator after a period of time after dispensing of said composition and mixing of said first component and said second component.

2. The soap of claim 1 wherein said indicator includes said soap changing in color.

3. The soap of claim 1 wherein said indicator includes said soap changing in viscosity.

4. The soap of claim 1 wherein said indicator includes said soap changing in smell.

5. The soap of claim 1 wherein said indicator includes said soap changing in sound.

6. The soap of claim 1 wherein said indicator includes said soap changing in temperature.

7. The soap of claim 1 wherein said indicator includes said soap changing in from a finite time to at most 5 minutes.

8. The soap of claim 6 wherein said indicator includes said soap changing in between 25 and 35 seconds.

11. The soap of claim 1 wherein said indicator includes said soap changing viscosity and color in from a finite time to at most 45 seconds after said components are mixed together.

12. The soap of claim 3 wherein said indicator includes said soap changing viscosity and color between 25 and 35 seconds after said components are mixed together.

13. The soap of claim 1 wherein said indicator includes said soap changing in from 10 to 45 seconds.

14. The soap of claim 1 wherein said indicator includes said soap changing in from a finite time to at most 2 minutes.

9. A soap for cleaning comprising a first component including liquid soap, a dye and polyvinyl alcohol, and a second component including borax, citric acid, ascorbic acid and iron chloride, wherein said components are mixable together to produce said soap.

10. The soap of claim 9 wherein said soap changes viscosity from a gel to a liquid and simultaneously changes color from green to blue.
