Abstract
A water-absorbent composition includes: a specific plant extract; a water-absorbent resin whose surface portion and/or periphery thereof is treated; and/or a water-absorbent resin having a specific property. Specifically, it is preferable to use a water-absorbent resin having three characteristics: (1) a specific neutralization rate, (2) a specific particle diameter, and (3) a specific plant extract. The water-absorbent composition has a superior deodorant performance and an absorbent characteristic when the water-absorbent composition is used (provided) in an absorbing product such as a paper diaper, thereby providing a superior deodorant performance and a superior absorbent characteristic to the foregoing absorbing product.
