ABSTRACT:
Effervescent compositions are disclosed. The effervescent composition may include at least one compound capable of effervescence in the presence of a liquid, such as water. The effervescent composition may also include a non-hygroscopic solvent. The presence of the non-hygroscopic solvent may assist the effervescent composition in substantially avoiding effervescence until the composition contacts a liquid. Optionally, the ratio of the at least one compound capable of effervescence to the non-hygroscopic solvent is not less than 9:1.
