Abstract:
A composition suitable for scavenging oxygen while inhibiting migration of its components comprising an oxidizable organic compound, a transition metal catalyst, and a photoinitiator selected from benzophenones represented by the formula: wherein:i) at least one R1, R2, R3, R4 or R5 is independently selected from a C2-C18 alkyl, a C2-C18 alkoxy, a phenoxy, a C5-C7, alicyclic hydrocarbon, an alkaryl, or a C1-C18 ester group, and the remainder of said R1, R2, R3, R4 and R5 are hydrogen atoms; and each R6, R7, R8, R9 and R10 is a halogen or hydrogen atom; or ii) at least one R1, R2, R3, R4 or R5 and at least one R6, R7, R8, R9 or R10 are each independently selected from a C1-C18 alkyl, a C1-C18 alkoxy, a phenoxy, a C5-C7 alicyclic hydrocarbon, an alkaryl, or a C1-C18 ester group, and the remainder of said groups are each halogen or hydrogen atoms; said photoinitiator being substantially non-migratory from the composition when exposed to a food simulant.
