Are Naturopatches preservative free?
Yes, the manufacturer takes steps to protect the fragile nature of the pure essential oils used. For example, the essential oils are stored in a temperature-controlled facility and are contained in dark bottles until they are needed. The oils are not infused into the patch until the last step and the backing on the patch protects against degradation. Also the tins are light tight and air tight to preserve the integrity of the essential oils.
