Abstract
Dual colorants are disclosed. The colorants of the present invention include at least one compound, which exhibits a first color outside an aqueous environment and a second color after placement into an aqueous environment. In some cases, the colorant includes an oil-soluble dye capable of exhibiting the first color and a water-soluble dye capable of exhibiting the second color. In certain embodiments, such colorants may be used in toilets. In these embodiments, the first color corresponds to a color associated with a fragrance, such as red for rose, while the second color corresponds to a color associated with cleanliness in a toilet, such as blue or green.
Claims23
A colorant comprising a plurality of dyes, consisting of:
- a fragrance,
- an oil-soluble dye capable of exhibiting a first color when in a non-aqueous environment, said color being indicative of said fragrance, and
- a water-soluble dye capable of exhibiting a second color when in an aqueous environment;
- wherein the colorant exhibits the first color before introduction to an aqueous environment, and wherein the first color and at least a portion of the aqueous environment exhibit the second color when said colorant has been inserted into an aqueous environment.
A process for treating water in a toilet bowl comprising:
- providing a composition comprising a colorant comprising a plurality of dyes, consisting of an oil-soluble dye capable of exhibiting a first color when in a non-aqueous environment, and a water-soluble dye capable of exhibiting a second color when in an aqueous environment;
- said composition further comprising at least one cleaning compound, wherein the composition exhibits said first color outside an aqueous environment;
- and
- placing the composition into an aqueous environment, wherein the first color and at least a portion of the aqueous environment exhibit said second color.
A process for making a colored composition useful for cleaning comprising:
- providing an oil-soluble dye capable of exhibiting a first color in the absence of an aqueous environment;
- providing a water-soluble dye capable of exhibiting a second color in an aqueous environment;
- and
- mixing the oil-soluble dye and the water-soluble dye with a cleaning material and an effervescent material comprising an acid and a salt
- and pressing the composition into a tablet.
