Abstract

A superabsorbent polymer includes polymeric particles, surface cross-linking agents and an extract of a plant of Sapindaceae. The polymeric particles have cross-linking inside the polymeric particles. The surface cross-linking agents are covalently bound to the surface of the polymeric particles so as to constitute a layer of surface cross-linked region at the surface of each polymeric particle, and the extract of the plant of Sapindaceae covers the surface of the polymeric particles.
