Vitamin E, also called tocopherol, is a natural preservative that protects vegetable oils and butters from rancidity. A powerful natural antioxidant, it is recommended to add it to your oily preparations, balms and macerates to extend their shelf life. It is also an anti-aging active ingredient recommended for dry and mature skin. Its cap with dropper insert allows the preservative to be dosed easily and accurately. Our vitamin E is a 100% natural preservative with a minimum tocopherol content of 50%.
