ABSTRACT:
There is provided a color change composition that remains stable in a single phase and that contains an indicator that produces an observable color change after a period of time to show that sufficient cleaning has been done or to indicate the thoroughness of the cleaning. This use indicating color change is useful for, for example, in soap for teaching children to wash their hands for a sufficient period of time. This composition may be added to many different base materials to indicate time of use or as a way to introduce enjoyment to the activity.
