Vitamin E oil is used in a number of products, such as shampoo and toothpaste 5. It contains antioxidant properties to protect your hair, teeth, organs and tissues from free radicals that can damage or destroy cells. While this sounds good, some people are allergic to vitamin E oil. In fact, the May 2010 issue of "The Journal of Clinical and Aesthetic Dermatology" states that vitamin E is the sixth most common allergen 4. Avoid using vitamin E products if you have a known allergy.

Function

Vitamin E is converted into a liquid form, known as vitamin E oil. Some manufacturers convert vitamin E into oil to include it in certain products, such as toothpaste, shampoo and skin care products. Converting vitamin E into an oil may help aid in the consistency of the product. Vitamin E is added to toothpaste to help strengthen gums and improve gum health, according to the December 2010 "International Dental Journal. 5"

Effects

Depending on which product contains vitamin E oil, it can affect you in different ways should it cause an allergic reaction. If your shampoo contains vitamin E oil, and you are allergic, you may experience a skin rash, itching and redness. If your toothpaste contains vitamin E oil, it could cause your tongue, throat or mouth to swell. Lotions that contain vitamin E oil may cause skin hives.

Time Frame

There is no set period as to how long it may take an allergic reaction to occur. If you are sensitive to vitamin E oil, you may experience an immediate allergic reaction or a severe allergic reaction. If you aren’t sensitive to vitamin E oil, it may take a few applications of the product, or even days or months, to develop an allergic reaction.

Warning

Should an allergic reaction occur, discontinue use of the product right away. For anaphylactic reactions, seek medical attention immediately. An anaphylactic reaction can cause your throat to swell shut, blocking off your oxygen. This may result in death if you do not receive immediate medical attention. If you notice hives, skin rashes or swelling, contact your doctor to seek proper treatment.

Considerations

Read product labels prior to using the item. Avoiding vitamin E oil can help reduce the risk of an allergic reaction. Let others know about your allergy; in the event that you should come in contact with vitamin E oil, they can seek medical assistance on your behalf.
