Abstract
The object of this invention is to maintain the absorbency like absorption rate, etc. at high level, enhance the fluidity in the dry state, prevent blocking or caking causing adhering to the device at the time of moisture absorption, prevent a surface tension of absorbed liquid such as urine from dropping in case where the water absorbent agent is in contact with the absorbed liquid, and stably increase the fluidity and the bulk density without losing the water absorbent property. The particulate water absorbing agent of the present invention includes a water absorbent resin, having a cross-linking structure, whose surface has been cross-linked by adding a surface treatment agent, wherein: (I) a mass average particle diameter (D50) ranges from 200 to 600 μm and 95 to 100 wt % of a particulate water absorbing agent whose particle diameter ranges from less than 850 μm to not less than 150 μm is contained with respect to 100 wt % of whole the particulate water absorbing agent, and (ii) a logarithmic standard deviation (σζ) of particle size distribution ranges from 0.25 to 0.45, and (iii) a compressibility rate ranges from 0 to 18%, and (iv) a surface tension of a supernatant liquid obtained in 4 minutes after dispersing 0.5 g of the particulate water absorbing agent in 50 ml of physiological saline whose temperature is 20 DEG C is 55 mN/m or more.
