Is Rosemary Oil Extract (ROE) a preservative?
No, Rosemary Oil Extract is an antioxidant, meaning that it will remove free radicals from your blend whether it is a lotion, soap, or oil. ROE is wonderful for adding life to oils and preventing them from going rancid, but it is not a preservative in the sense of bacterial inhibition. Bacteria can still grow in your products if ROE and water are both present.
