I got a recipe that came with my soap mold to make a goats milk, brown sugar, oatmeal m&p soap. The soap recipe calls for vitamin E as a preservative Does anyone know if that is the Vitamin E oil you find in the beauty dept or the vitamin E in the capsules Also can you add EO's to melt n pour soap. I have peppermint, tangerine, and lavender eo's? Thanks for any help you can give this newbie.
