Abstract: Self-adhesive detergent compositions are described including a pH-sensitive color-changing system. The color-changing system is useful with certain acidic compositions and certain alkaline compositions. The compositions have a given color upon application to a hard surface, e.g., a toilet bowl. In one embodiment, when the self-adhesive composition is exposed to a water-based rinse, such as on flushing a toilet, the color-changing system provides the released cleaning portion of the composition, and thereby the water, with a color different from the color of the composition to indicate cleaning is occurring. In another embodiment, following exposure to a plurality of rinses, the color-changing system changes the color of the composition when the composition is near depletion to provide an “end-of-use” cue. In another embodiment, the color-changing system indicates dual functions by changing the color of the composition to another color when the composition is physically mixed with a rinse to provide manual cleaning.
