ABSTRACT:
A composition and method useful to quickly and effectively indicate whether a functional component such as catalase has been added to a clear solution such as a hydrogen peroxide solution involves compounding with the functional component an effective amount of vitamin B-12 such that when the compounded composition is added to the clear solution, the clear solution turns rose colored. By observing the rose color, the user can determine that the functional component has been added to the clear solution.
