What is Vitamin E?
Vitamin E is one of the most famous and well used vitamins in cosmetics. Vitamin E is a fat soluble vitamin, and will often be listed on ingredients lists as tocopherol which is the most biologically available form of Vitamin E.
Vitamin E is a great antioxidant and free radical scavenger, and can help protect the skin from environmental damage and stress. It improves the skin's moisture barrier, helping keep it moisturised and healthy.
Vitamin E Benefits
Vitamin E is excellent for scar and stretch marks; you'll find it as a prominent ingredient in products like Bio Oil.
It is also used as an antioxidant to protect products from oxidation (note, not as a preservative). So while Vitamin E is naturally found in many carrier oils, if you want to extend the shelf life and prevent oxidation, you can actually add a small amount of Vitamin E to the bottle!
How to use Vitamin E
Vitamin E oil is typically used at 0.5% as an antioxidant in formulations but can be used at higher amounts for its skincare benefits. But don't go too high or it will make your product sticky. I recommend not going above 2%.
Solubility of Vitamin E
Vitamin E is oil soluble, and is easily incorporated into oil based products, as well as emulsions.
It can be solubilised into water based products with Olivem 300.
The pH of Vitamin E
As Vitamin E is an oil, it doesn't have specific pH considerations. Simply adjust the pH to skin levels of around 5, or to the specifications of other actives, if using.
