WATER-ABSORBABLE RESIN COMPOSITION

WIPO Patent Application WO/2022/085755

A1

[Problem] The purpose of the present invention is to provide a novel water-absorbable resin composition having superior deodorizing ability than the conventional water-absorbable resin compositions. [Solution] One embodiment for achieving the purpose is a water-absorbable resin composition which comprises a water-absorbable resin and at least one of a hydrophobic porous polymer adsorbent and a resin having a nitrogenated heterocyclic ring and which has a span value of 1.10 or less wherein the span value is expressed by formula 1. D(90%) represents a particle diameter (unit: μm) such that the cumulative amount from the minimum diameter becomes 90% in a cumulative particle diameter distribution of particles; D(10%) represents a particle diameter (unit: μm) such that the cumulative amount from the minimum diameter becomes 10% in a cumulative particle diameter distribution of particles; and D(50%) represents a particle diameter (unit: μm) such that the cumulative amount from the minimum diameter becomes 50% in a cumulative particle diameter distribution of particles; wherein each of D(90%), D(10%) and D(50%) is a mass-based cumulative value.
