Abstract:
An oxygen scavenger comprising a mixture of hydroxosulfitometlate and a separate, water soluble transition metal compound, said separate, water soluble transition metal compound having a transition metal component, and said hydroxosulfitometalate (HSM) comprising between 0.05 and 90 weight percent of said mixture and represented by the formula:â€ƒMIMII2OH(SO3)2.H2Owherein MI represents a monovalent cation and MII represents a divalent cation; and said separate, water soluble transition metal compound is present in the mixture in an amount such that the molar ratio of the HSM to the transition metal component of the separate, water soluble transition metal compound is from 3000:1 to 1:1.
