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 (Na2SO4) and monopotassium phosphate (KH2PO4). 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. L'invention concerne l'utilisation d'une composition décolorante pour éliminer les substances colorées de liquides aqueux (par exemple, pigments colorés, liquides contenant du sang, etc.). La composition décolorante selon l'invention contient un ou plusieurs sels inorganiques. Selon un mode de réalisation de l'invention par exemple, la composition contient un mélange de sulfate de sodium (Na2SO4) et de phosphate monopotassique (KH2PO4). La composition décolorante peut être placée en communication fluidique avec un coeur absorbant, une couche perméable aux liquides ou des combinaisons des deux dans un article absorbant pour faciliter la décoloration des liquides contenant du sang (menstruations, par exemple) s'écoulant du corps.
