Abstract
Disclosed herein is a personal care absorbent article such as a feminine hygiene absorbent personal care article for receiving a body exudate such as menses. The article includes a topsheet layer, a backsheet layer, at least one absorbent core layer positioned between the topsheet layer and the backsheet layer, optionally a pair of wings, and a decolorization means associated with the article for altering the visual appearance and/or physical characteristics of the a body exudate. The use of the decolorization means provides several benefits to the end user including the creation of a visually smaller stain on the top surface of the topsheet layer and a possible reduction in staining of the wearer's apparel should the body exudate leak from or off of the article being worn.
