Aluminum essential oil bottle

I read an interesting piece recently about the packaging of essential oils.

The author writes: “To avoid deterioration and protect the aromatic and therapeutic properties of your essential oils, store them in amber or cobalt blue bottles. Dark glass such as amber or cobalt helps to keep out deteriorating sunlight. . . . Some vendors sell oils in lined aluminum bottles. It has been said that aluminum bottles are acceptable if the interior of the bottles are lined.”

The truth is – most essential oils can be stored easily in plain aluminum; in a few cases, epoxyphenolic coatings are used to line the sides. You have to do stability testing to determine which bottle is best for your product.
