Abstract
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.
Claims23
An article of manufacture comprising a fibrous substrate, said fibrous substrate containing an odor control composition, wherein said odor control composition comprises high-surface area particles bonded with an odor-reducing quinone compound, the high surface area particles comprising silica, alumina, or combinations thereof and having an average size of less than 100 nanometers and a surface area from about 50 square meters per gram to about 600 square meters per gram, the odor control composition configured to adsorb at least one odorous compound wherein said odor-reducing quinone compound is 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.
An absorbent article comprising at least one liquid transmissive layer and a liquid absorbent core, wherein said liquid-transmissive layer, said liquid-absorbent core, or combinations thereof, contain an odor control composition, said odor control composition comprising an odor-reducing quinone compound bonded with high surface area particles, the high surface area particles comprising silica, alumina, or combinations thereof and having an average size of less than 100 nanometers and a surface area from about 50 square meters per gram to about 600 square meters per gram, the odor control composition configured to adsorb at least one odorous compound wherein said odor-reducing quinone compound is 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.
