Abstract
A time duration of end of product life indicator is disclosed which utilizes a volatile dye coated or impregnated into a substrate or carrier. The dye evaporates as a volatile component of the product evaporates thereby changing the color of the substrate or carrier. The consumer is alerted to the depletion of the volatile component of the product when the substrate or carrier changes from a colored or dyed state to an uncolored state. As a result, a visual time duration or end of product life indicator is provided.
