Transition metal carboxylates as catalysts for oxygen scavenging

摘要

Disclosed herein are oxygen scavenging compositions and packaging articles that comprise (a) a metal catalyzed oxidizable compound and (b) at least one of a transition metal carboxylate, wherein the transition metal carboxylate comprises at least one carboxylate group and wherein each carboxylate group comprises between 20 and 30 carbon atoms, inclusive, such as cobalt behenate or cobalt arachidate.
