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.
Most essential oils producers have been packing essential oils and flavors in aluminum bottles for decades. They’re clearly more light-proof than glass bottles and have the added advantage of being lightweight, leak-proof and tamper-proof. Even if aluminum bottles seem more expensive than glass, the cost of protecting a glass bottle, the risk of breakage as well as the added shipping cost have to be factored in when comparing.
Our aluminum bottles for essential oils can come as small as 19 ml (.6 oz.) and all the way up to 32 liters (1,082 oz.). So we have a wide range of options for both retail and industrial packaging.
