Abstract
A superabsorbent polymer composition exhibiting very improved antimicrobial and deodorizing properties while maintaining basic absorption performance, and can significantly reduce the generation of dust during the application for a process, and thus fulfills both stability and processability and can be usefully applied for hygienic goods such as a diaper and the like. The superabsorbent polymer composition includes: a) superabsorbent polymer particles including a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, of which at least a part are neutralized, and b) an antimicrobial agent having a controlled particle size, containing a chelating agent including EDTA or an alkali metal salt thereof; a mixture of an organic acid and a silicate-based salt; and an agent for controlling a particle size.
