The use of a decolorizing composition for removing colored substances from aqueous fluids (e.g., colored pigments, blood-containing fluids, etc.) is provided. The decolorizing composition contains one or more inorganic salts. In one embodiment, for example, the composition contains a mixture of sodium sulfate (NaSO) and monopotassium phosphate (KHPO). The decolorizing composition may be placed in fluid communication with an absorbent core, a liquid-permeable layer, or combinations thereof, in an absorbent article to help decolorize blood-containing fluids (e.g., menses) exuded from the body.
