Abstract
The present invention has an object to provide a particulate water-absorbing composition, a production process therefor, and an absorbent article comprising this particulate water-absorbing composition, wherein the particulate water-absorbing composition causes little coloring of other materials and further is of high safety, and can provide excellent deodorizability and excellent absorption properties to absorbent articles such as diapers in the case where combined into the absorbent articles. As a means of achieving this object, a particulate water-absorbing composition according to the present invention is characterized by comprising a plant powder and a water-absorbent resin, wherein a surface portion and/or its vicinity of the water-absorbent resin is surface-treated with a crosslinking agent, and wherein the particulate water-absorbing composition exhibits an offensive-odor removal index of not less than 180 wherein the offensive-odor removal index is represented by the following equation: offensive-odor removal index=1.1×hydrogen sulfide removal ratio+2.0×methylmercaptan removal ratio+0.3×ammonia removal ratio.
