Claim:
A composite article comprising a ClO 2 -producing material integrated into a hydrophilic organic matrix and optionally one of fibrous materials, plasticizers, pore formers, colorings, fragrances, desiccants, or combination thereof, wherein the ClO 2 -producing material comprises a chlorite-containing compound and an acidifying agent in an intimate physical mixture, wherein the composite article releases ClO 2 when contacted by an activating stimulus comprising water vapor or water, and wherein light is not an activating stimulus for the composite article, and wherein the hydrophilic organic matrix: a) is formable at a temperature below about 150° C.; b) permits at least some contact between the activating stimulus and the ClO 2 -producing material when the composite article is exposed to the activating stimulus; and c) is permeable to ClO 2 .
