Antioxidant Content of and Migration from Commercial Polyethylene
Antioxidants commonly used in polyolefins were studied in commercial food packages made of low- and high-density polyethylene (LDPE and HDPE), polypropylene (PP), polyvinylchloride (PVC), and polyethylene terephtalate (PET) and in a LDPE film extruded at the laboratory. The phenolic antioxidants BHA, BHT, AO 2246, AO 425, Ethanox 330, Irganox 1010, and Irganox 1076 were studied together with
Natural Flavonoid-Functionalized Silk Fiber Presenting Antibacterial
Natural bioactive compounds as promising alternatives to synthetic finishing agents have recently gained increasing attention in the textile industry due to their eco-friendliness, low irritation, and biocompatibility. The present study reports a sustainable approach for preparing antibacterial, antioxidant, and UV-protective silk fiber using two natural flavonoids (quercetin and rutin) by an

Antioxidants | Additives for polymers | ADEKA Polymer Additives Europe
Phenolic antioxidants are radical scavengers which prevent thermal degradation of many organic materials such as polymers. Their effectiveness increases when used in combination with phosphites, thioethers and light stabilizers.
Phenolic Antioxidant - an overview | ScienceDirect Topics
The antioxidant's main purpose is to protect the organic substrate during processing or conversion including the stretching step. The phenolic antioxidant concentration present for processing or conversion usually is enough to extend the organic substrate life time beyond the service life-time requirement.
Antioxidant - an overview | ScienceDirect Topics
Antioxidants are used in many applications, and the chemistry of these materials has been reviewed 〈92KO(3)424〉. For example, the degradation of polymers may be inhibited by the addition of antioxidants, and the most important chain transfer antioxidants are phenols and aromatic amines 〈B-79MI 506-05, 80PAC365〉.

Antioxidant serums give you more youthful, even-toned skin. Here, doctors share how to choose the best one for your skin type, plus the best products to try.
Stabilizers are a class of chemical additives commonly added to polymeric materials, such as plastics, to inhibit or retard their degradation. Polymers can be subject to various degradation processes, including oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues or other impurities.
