Abstract

A superabsorbent polymer composition includes superabsorbent polymer particles, a chelating agent and a mixture of an organic acid and a silicate-based salt. The superabsorbent polymer particles include crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, of which at least a part are neutralized, and the chelating agent includes EDTA or an alkali metal salt thereof, exhibiting improved antimicrobial and deodorizing properties without deterioration of the superabsorbent polymer properties such as centrifugal retention capacity.
