Abstract
A deoxidant composition comprising 100 parts by weight of iron powder, 0.01 to 20 parts by weight of metal halide and 0.01 to 5 parts by weight of water repellent agent. The deoxidant composition even when used in a high-humidity atmosphere can maintain oxygen absorption potency. A deoxidant pack for high humidity obtained by wrapping the deoxidant composition without mixing of any inorganic filler by means of an air-permeable packaging material can reduce the apparent volume of deoxidant composition, so that the amount of packaging material used in the production of the deoxidant pack can be reduced.
