摘要： Provided is a water-absorbing resin composition that is capable of achieving both high liquid diffusion and liquid leakage prevention in an absorbent. The present invention provides a water-absorbing resin composition, wherein: an electromotive force P(mV) of a first-washing washing liquid, obtained as a result of washing the water-absorbing resin composition by means of the washing method indicated below, is equal to or greater than 80 V; and the difference (P-Q) between the electromotive force P(mV) and an electromotive force Q(mV) of a second-washing washing liquid, obtained as a result of washing the water-absorbing resin composition by means of the washing method indicated below, is equal to or greater than 10 mV. (Washing method) A container in which a sieve having a mesh size of 36 µm is attached to the bottom of a cylinder having an inner diameter of 60 mm is prepared. 1 g of the water-absorbing resin composition is evenly dispersed on the sieve in the container. A 200 mL beaker is placed under the sieve. 200 g of a physiological saline solution is rapidly introduced from above the water-absorbing resin composition and the physiological saline solution that has flowed down into the beaker is used as the first-washing washing liquid. Next, a new 200 mL beaker is placed under the sieve. An additional 200 g of the physiological saline solution is rapidly introduced from above the water-absorbing resin composition and the physiological saline solution that has flowed down into the beaker is used as the second-washing washing liquid.

摘要： Provided is an absorbent article comprising water-absorbent resin particles and an activated carbon, which has an excellent deodorizing effect. An absorbent article comprising at least a liquid-permeable sheet; a liquid-impermeable sheet; and an absorbent material comprising water-absorbent resin particles and an activated carbon, disposed between the liquid-permeable sheet and the liquid-impermeable sheet, wherein the absorbent material comprises water-absorbent resin particles, and the water-absorbent resin particles have a heat release rate of 0.10°C/sec or more and 1.00°C/sec or less as measured by the following method of measuring the heat release rate:
(Method of Measuring the Heat Release Rate)
50 g of physiological saline at 24.9°C is added into a 300 mL volume, cylindrical thermally insulated container and stirred at 600 rpm;
while stirring the physiological saline, 10 g of the water-absorbent resin particles are further added into the thermally insulated container, and the thermally insulated container is closed with a cork stopper having a thermometer; and
a time required for the temperature of the physiological saline to increase by 2.0°C after the addition of the water-absorbent resin particles is measured, and a value of heat release temperature per second is calculated as the heat release rate.

摘要： Provided is a water-absorbing resin composition containing water-absorbing resin particles and activated carbon. When the water-absorbing resin composition is used in an absorbent article, a gel of the water-absorbing resin composition that has absorbed water is stable in an environment during ordinary usage (wearing) of the absorbent article. After the absorbent article is used, the gel strength can be adjusted to a suitable strength for disposal (gel separation operation) by processing for a long time under high-temperature conditions. The water-absorbing resin composition contains the water-absorbing resin particles and activated carbon disposed on the surface of the water-absorbing resin particles. The water-absorbing resin particles are subjected to a surface-crosslinking process, and the physiological saline solution absorption amount of the water-absorbing resin particles is 30 to 80 g/g.
