Why do some companies use grapefruit seed extract and Vitamin E to preserve their products?
Grapefruit seed extract and vitamin E are not full spectrum preservatives that kill both bacteria and mold. Vitamin E is an antioxidant that is great for keeping oils from going rancid but it will not kill bacteria. When a product contains water, bacterial contamination and its ability to cause infection to a consumer is far greater than the risk posed by utilizing a preservative.
