Tocopherol (Vitamin E, E306)
Tocopherol is the main member of the vitamin E family. In cosmetics it is used both as an antioxidant that protects the product's oils and as a skin-softening care ingredient, and in food as a natural antioxidant preservative under the code E306. It is one of the safest ingredients known; allergic skin reactions can occur, but rarely.
Risk range
1 is the lowest and 10 the highest risk. The range depends on the amount used, whether the product is rinsed off and how it is used. The Temiz İçerik app uses the same ranges.
The range is very low; the upper end is for the rare possibility of contact allergy.
The amounts added to food are very small; the upper end only reflects the overall assessment of the product itself (for example a fatty snack).
What is tocopherol and what does it do?
Vitamin E is a fat-soluble vitamin that protects cell membranes in the body against oxidative damage. “Tocopherol” is the chemical name of this vitamin; it has different forms: alpha, beta, gamma and delta. It occurs naturally in vegetable oils, nuts and seeds.
In products it has two jobs: delaying the oils they contain from oxidising and going rancid, and, in cosmetics, providing softness and moisture support for the skin. The form seen on labels as Tocopheryl Acetate is a more stable ester and is partly converted into free vitamin E in the skin.
Which products contain it?
- Moisturisers, after-sun and anti-ageing creams
- Lip balms, body oils and hair care products
- Vegetable oils, margarines, breakfast cereals and infant formula (E306–E309)
- In serums together with other antioxidants (vitamin C, ferulic acid)
In food, E306 refers to mixed natural tocopherols, while E307–E309 refer to synthetic forms.
Is it safe? The scientific assessment
The independent Cosmetic Ingredient Review (CIR) panel has found tocopherol and its derivatives safe at the levels used in cosmetics. EFSA has also re-evaluated tocopherols as food additives and saw no safety concern in their permitted use. Food additive legislation in Türkiye is aligned with the EU.
The most significant side effect reported in cosmetics is contact dermatitis, which is quite rare; it can occur particularly on irritated skin or with high-concentration oils. The amounts added to foods as additives are small compared with the vitamin levels obtained from the diet.
It is important here to distinguish between an additive and a supplement: long-term use of high-dose vitamin E supplements can increase the risk of bleeding, especially in people taking blood thinners. This does not apply to the levels found in cosmetics or food additives.
Who should be careful?
- People who have previously reacted to creams containing vitamin E: They can check labels for Tocopherol and Tocopheryl Acetate.
- People taking blood thinners: Creams are not a problem; consult a doctor before taking high-dose supplements.
- Very acne-prone skin: Pure vitamin E oil can feel heavy; lighter formulas may be preferable.
What to do when you see it on a label
Tocopherol is an ingredient you can comfortably accept on a label. It is even seen as a good alternative to synthetic antioxidants such as BHA and BHT. When used together with ascorbic acid (vitamin C), the two are known to support each other's antioxidant effect.
Frequently asked questions
Is E306 natural?
E306 refers to mixed tocopherols obtained from vegetable oils. E307–E309 are synthetic forms of the same vitamin; all are permitted and considered safe.
Is pure vitamin E oil good for scars?
Evidence that it reduces scarring is weak and contradictory; in some people it can also irritate the skin.
Is there a difference between tocopherol and tocopheryl acetate?
Tocopheryl acetate is a more stable form of vitamin E and does not degrade during the product's shelf life. It is partly converted into free tocopherol in the skin.
