Uses

 Vitamin E Acetate (CAS NO.54-22-8) is used as an alternative to tocopherol itself because the phenolic hydroxyl group is blocked, providing a less acidic product. 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. It is often used in dermatological products such as skin creams.

Specification

Tocopheryl acetate, also known as vitamin E acetate, is a common vitamin supplement with the molecular formula C31H52O3 (for 'α' form). It is the ester of acetic acid and tocopherol (vitamin E).
