Antioxidant segregation and crystallisation at polyester
Multivariate statistical methods (PCA) allowed us to quantify the additive surface concentration in the lower concentration range (≤0.3 wt.%). ToF-SIMS imaging confirmed the uniform surface covering and, for higher concentration (5.5 additive wt.%), showed the formation of additive crystals on the top of the additive covered PETI surface.

Polymorphism of Irganox 1076®: Discovery of new forms
Antioxidants are usually highly soluble in the polymer at elevated processing temperatures, but on cooling, the polymer may become supersaturated with the stabilizer. This can result in a surface segregation and a crystallization process of the additive , in one of its polymorphic

Emerging Roles of Propolis: Antioxidant, Cardioprotective,
The antioxidant capacity of propolis may be related to some of its biological effects, including chemoprevention. The flavonoids in propolis are powerful antioxidants, capable of scavenging free radicals and thereby protecting the cell membrane against lipid peroxidation [42].
