This invention pertains to a polymeric composition and an antimicrobial composition, each comprising a superabsorbent polymer (SAP), such as used in diapers and sanitary napkins, and peroxide. The superabsorbent material can be made by the process of treating a preformed SAP, such as a crosslinked polyacrylate salt, with a treatment solution comprising hydrogen peroxide dissolved in water, followed by drying. The resulting superabsorbent material has strong antimicrobial activity. Optionally, the treatment solution may also contain a metal salt, including those of zinc, zirconium, and magnesium.
A polymeric composition comprising sequestered peroxide, produced by treating a superabsorbent polymer with at least 0.005 grams of hydrogen peroxide per gram of superabsorbent polymer, wherein said treatment comprises swelling the superabsorbent polymer with an aqueous treatment solution comprising aqueous hydrogen peroxide, followed by drying.
An antimicrobial composition produced by treating a superabsorbent polymer with at least 0.005 grams of hydrogen peroxide per gram of superabsorbent polymer, wherein said treatment comprises swelling the superabsorbent polymer with an aqueous treatment solution of hydrogen peroxide, followed by drying of the treated superabsorbent polymer, whereby addition of 0.2 grams of the antimicrobial composition to approximately 1,000,000 viable bacteria in an aqueous liquid produces a 3-log reduction of viable bacteria in said aqueous liquid.
