Features & Benefits
- Product Info
Whilst Vitamin E is technically not a preservative, much like parabens/preservatives in commercial cosmetics, Vitamin E can be used to “preserve” oil-based skincare products. Vitamin E prevents oxidation of oils and is often referred to as an antioxidant. Since oils are fats, and since fats start to oxidize when exposed to air, even these simple skincare recipes need to be “preserved” somehow, or they will go rancid over time. In order to “preserve” oils, you need to prevent the natural oxidation process. Oxidation is a chemical reaction which produces free radicals, which in turn create a chain reaction that damages the oils. Antioxidants (like Vitamin E) are great at preserving the life of oils as they terminate these reactions and therefore prevent oxidation. Whilst oxidation may not be an issue for a quickly used product like a face mask, with products that tend to take a few months to use like homemade natural Deodorant, Vitamin E shouldn’t be skipped. Vitamin E cannot be used for products containing water - for this you will require other preservatives (like parabens) to prevent microbial growth through antimicrobial effects.There are two types of Vitamin E. There’s the type you can put on your skin for added benefits (like reducing fine lines), and there’s the type you can add to skincare product to increase its shelf-life and stability.
