Vitamin E is the name of a group of compounds including tocopherols and tocotrienols. Its study developed in the 20th century with the understanding of food ingredients needed by organisms in small amounts. Unlike vitamin C, it is fat-soluble, which is important for its presence in food and recipe design.
Characteristics and context
Natural sources include vegetable oils, seeds and nuts. Vitamin E also appears in cosmetics, where the INCI list includes the names Tocopherol and Tocopheryl Acetate. These are different chemical forms, and a cosmetic applied to the skin is not a supplement for consumption. The compound may also play a role in protecting the fat part of the recipe from oxidation. It is worth distinguishing this technological function from the description of the finished product and its purpose.
The name vitamin E appears on both supplements and cosmetics. This does not mean that these products are used interchangeably. An ingestible capsule and a care oil have a different purpose, formula and evaluation method. First determine the product category and only then compare the content. Do not use the cosmetic orally and do not use the capsule as a cosmetic without the manufacturer's recommendation.
Meaning and application
Tocopherol and Tocopheryl Acetate are examples of names found in the INCI list. The presence of an ingredient does not tell you what its exact concentration is or what the overall formula is. The vitamin may contribute to the caring nature of the product or to protect the formulation against oxidation. Also evaluate the cosmetic according to its purpose, other ingredients and indicated method of use.
Read the amount of vitamin E in a serving and the percentage of RDA in the table. Do not directly compare the mass of the vitamin with the mass of the carrier oil. Also check other preparations, because vitamin E may be present in multivitamin mixtures. Comparing different units and forms requires knowledge, so if a declaration is unclear, ask for clarification instead of guessing the conversion factor.
In practice
The word antioxidant describes a biological role, not a guaranteed effect of any product. It is also not a recommendation to increase the amount of the supplement. For a cosmetic, it will be important to match the formula to the skin, for a supplement, the full label and diet. Separating these two uses allows you to avoid comparing things that only have similar words on the packaging.
