Tocopheryl acetate , also known as vitamin E acetate , is a common vitamin supplement with the molecular formula C ₃₁ H ₅₂ O ₃ (for 'α' form). It is the ester of acetic acid and tocopherol (vitamin E). It is often used in dermatological products such as skin creams. Tocopherol acetate is not oxidized and can penetrate through the skin to the living cells, where about 5% is converted to free tocopherol and provides beneficial antioxidant effects.

Tocopheryl acetate is used as an alternative to tocopherol itself because the phenolic hydroxyl group is blocked, providing a less acidic product with a longer shelf life. It is believed that the acetate is slowly hydrolyzed once it is absorbed into the skin, regenerating tocopherol and providing protection against the sun's ultraviolet rays.

alpha-tocopherol has two functions: it acts as a vitamin (vitamin E) and it acts as an essential antioxidant. Vitamin E can not be synthesized by the body and must therefore be supplied in the diet or through supplementation.

The extremely critical role of alpha-tocopherol in protecting against free- radical reactions becomes apparent:

• Aging
• Many types of cancer
• Atherosclerosis and other circulatory diseases
• Arthritis
• Cataract formation
• Senile dementia (Alzheimer type)
• Respiratory diseases induced by pollution
