The composition of the invention is manufactured using solely dry constituents, thereby obviating an intensive drying step and resulting in substantial savings as well as simplifying the manufacturing process. The compositions of the invention find particular utility in applications involving the controlled generation of chlorine dioxide for a sustained period of time for the preservation of boxed fruits and vegetables during transportation or in deodorizing enclosed spaces such as refrigerators or lockers.Field of SearchComposition containing two or more solid materials with defined physical dimensions; e.g., surface areas, volumes, etc., or process of producing said compositionPlural oxidants Composition containing a stabilizer or a product in the form of a surface-modified, impregnated, encapsulated, or surface-coated article; or process of producing said composition Contains elemental material devoid of water Contains free halogen or oxy-halogen acid type Contains alkaline earth metal Chlorite Hypochlorite Alkali metal hypochlorite Alkaline earth metal hypochlorite |
