Synthetic mixtures of additives (antioxidants, UV stabilizers) used in the manufacture of food packaging materials were separated by normal phase HPLC under isocratic or gradient elution, and by capillary SFC using CO 2 as mobile phase. SFC proved to be more efficient for the separation and determination of additives with a wide range of

Nevertheless, HPLC is still generally used for the determination of antioxidants and UV stabilizers in plastic extracts [12][13][14]. Substances separated by GC can be identified by GUMS. On the other hand, structure determination of plastic additives and contaminants by LC/MS is rarely performed, probably because of the practical difficulties

In addition to their role as UV stabilizers, they are also known to act as AOs as they trap free radicals. Particularly oligomeric variants are used with this dual purpose in mind, with their relatively high molar mass slowing down loss from polymers by reducing migration [14-17]. The separation of stabilizers is commonly realized by HPLC.

Antioxidants are used to prevent thermal degradation and inhibit oxidation (i.e. degradation). They are “cheap” insurance for multiple pass materials. Antioxidants are generally divided into primary and secondary categories. Each category has a specific function in polymer stabilization. Primary – used to protect the finished product.
