An odor control composition that comprises an odor-reducing quinone compound and optionally high surface area particles is provided. In one embodiment, the odor-reducing quinone compound is an anthraquinone having the following structure: wherein the numbers 1 through 8 refer to optional substitution positions for functional groups. For example, positions 5 through 8 of the anthraquinone may be unsubstituted with functional groups. Examples of such quinone compounds may include those obtained from a dye selected from the group consisting of Acid Blue 25, Acid Green 41, Acid Blue 45, Mordant Violet 5, Acid Blue 129, Acid Green 25, D&C Green No. 5, Acid Green 27, and combinations thereof.
