Provided is a particulate water-absorbing agent excellent in handleability with a powder and a particulate water-absorbing agent suitable for multiple uses having high absorption performance in a wide range of salt concentrations. The particulate water-absorbing agent is mainly composed of a polyacrylic acid (salt) -based water-absorbing resin, and is water-insoluble or sparingly water-soluble selected from long-chain alkyl compounds, organic polysiloxanes, and organic polymer compounds. A particulate water-absorbing agent containing 0.001 to 5% by weight of a compound (however, when a long-chain alkyl compound corresponds to a metal soap, 0.001% by weight or more and less than 1.0% by weight), and an impact test The subsequent moisture absorption blocking rate is 0 to 30 wt%, and the 20 wt% saline vertical absorption index is 1.5 to 10.0 [g / g]. |
