An essential oil bottle is designed to both house and dispense essential oils. Although some essential oil bottles are made from impermeable plastics like PET, the vast majority of essential oils are packaged in glass bottles because essential oils are extremely potent. Many types of essential oils are corrosive enough to break down plastic containers over time, making plastic an unpopular choice for bottling most types of essential oils. Glass bottles are inert and won’t deteriorate when exposed to essential oils.
Types of Essential Oil Bottles
Essential oil bottles come in many different sizes, typically ranging from 1ml to 30ml. But the 10ml bottle is by far the most frequently used size for packaging pure essential oils. Bottles as large as 4oz can be used with some types of essential oils products. These larger containers typically house diluted essential oil-infused products like room sprays or body misters.
Nearly every essential oil bottle comes with a cap dispenser. The most common types are a dropper insert and a dropper cap. Dropper inserts are a popular choice, because they allow for very precise control over how much oil is used. Dropper inserts are flat caps that allow single drops of oil to be easily dispensed. There are two main types of dropper inserts. A vertical dropper dispenses single drops of oil when turned upside down, while a horizontal dropper dispenses oil at the rim when tilted sideways.
There are four common options for colored glass for essential oil bottles:
- Amber or Brown
- Flint or Clear
- Cobalt Blue
- Green
