Tocopherols
Tocopherols, a class of organic compounds consisting of various methylated phenols, many of which exhibit vitamin E activity. Named tocopherol from the Greek words τόκος (tókos) meaning 'birth' and φέρειν (phérein) meaning 'to bear or carry', indicating 'to carry a pregnancy', with the suffix '-ol' denoting its status as a chemical alcohol. α-Tocopherol is predominantly found in supplements and the European diet, primarily sourced from olive and sunflower oils, whereas γ-tocopherol is more common in the American diet due to higher consumption of soybean and corn oil.
Tocotrienols, related compounds, also possess vitamin E activity. All these derivatives with vitamin activity are correctly referred to as "vitamin E." Tocopherols and tocotrienols act as fat-soluble antioxidants and have various other functions in the body.

Uses in Cosmetics
Tocopherols offer several benefits in cosmetics, including:
Acting as potent antioxidants, protecting the skin from free radical damage.
Enhancing the skin's repair capability and helping to mitigate UV damage.
Maintaining product stability and preventing oxidation of cosmetic fatty components.
The use in food
As natural antioxidants, tocopherols help protect food from oxidation, extending shelf life, and offer health benefits, including:
Strengthening the immune system.
Protecting cells from free radical damage.
Reducing the risk of cardiovascular diseases.
Source
Tocopherols are primarily extracted from plant oils, including:
Soybean and corn oil (rich in γ-tocopherol).
Olive and sunflower oil (rich in α-tocopherol).
Separated and purified from seed oils through chemical or physical methods.
Globally Harmonized System of Classification and Labelling of Chemicals
Tocopherols, as food additives and cosmetic ingredients, are safe to use at recommended doses, with good tolerance and low allergenic potential.
