Provided is a novel oxygen absorbent composition that is capable of realizing an oxygen absorbent that does not respond to metal detectors, an increase in odor strength after oxygen absorption being suppressed in the oxygen absorbent composition, and the oxygen absorbent composition exhibiting an excellent oxygen-absorbing performance under broad humidity conditions from low humidity to high humidity. Also provided is an oxygen absorbent packaging, etc., in which the oxygen absorbent composition is used. This oxygen absorbent composition includes: at least one compound having a tetralin ring represented by general formula (1); and a transition metal catalyst. (In formula (1), each of R 1 -R 8 independently represents an oxygen atom or a monovalent substituent; the monovalent substituent being at least one type selected from the group consisting of a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxy group, a carboxyl group, an ester group, an amide group, a nitro group, an alkoxy group, an aryloxy group, an acyl group, an amino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group, and an imide group. The monovalent substituent may further have a substituent, and two substituents from amongst R 1 -R 8 may bond and form a ring.) |
