An odor masking tablet composition includes a solid single-use tablet comprising at least one base oil, a reactive agent, a base material, and an emulsifier. The tablet is packaged for individual use and transportation, or multiple tablets are packaged together. The tablets function to rapidly dissolve when deposited into toilet water and produce an active surface barrier for trapping unpleasant odors within the water. The tablets also include a scented material, and a coloring agent for changing the color of the water to which the tablet is placed.
