Global migration and specific migration of antioxidants (AOs)—Irgafos 168 [tris(2,4-di-tert-butylphenyl) phosphite], Irganox 1076 [octadecy13-(3,5-di-tert-butyl-4-hydroxyphenyl-propionate], and Hostanox SE2 (disteary thiodipropionate)—from polypropylene (PP) films into food simulants (water, 3% acetic acid, 95% ethanol, olive oil, and heptane) were studied. Films (50, 100, and 200 μm thick) were exposed to simulants at temperature-time conditions simulating migration under retorting and long-term storage. Global migration into aqueous simulants was independent of film thickness and conditions of exposure, so it seems as if the migration process was limited to the dissolution of migrants on the contacting surface. Global migration to fatty food simulants was dependent on simulant, conditions of exposure, and in some cases film thickness. Specific AO migration was analyzed from dry residues obtained from global migration analysis. Migration of AOs into aqueous simulants was below the detection limit (0.01 mg/dm2). Migration into fatty food simulants was dependent on the simulant. The extractive power of simulants was similar to that observed in global migration studies. Specific migration into heptane was independent of the polymer mass, though dependent on the thickness. Migration into ethanol was dependent on both mass and thickness. A theoretical discussion about the controversial effect of thickness on migration results, based on the kinetics of the process, is presented.
