Dear Dr. Ellie
Is it a good idea to add a natural vegetable color to the closys, since it is clear, for someone with poor vision to be able to better see how much is actually being poured?
I would not suggest adding color. I do not know what the outcome would be and I am concerned that the color could stain teeth.
Soon we will be selling a 64 oz Closys in a jug style container. This large size Closys comes with a neat little pump that fits in the top of the jug.
I would suggest that this could be a solution for someone with poor vision. They would know that one pump would dispense the correct amount into a cup.
The 1.5 ml Listerine bottles also have a pump available (that we sell) and this could provide a similar way to dispense the correct amount of Listerine.
What do you think?
Thanks for your interest,
