Yes, clove oil does expire, although its shelf life can be relatively long compared to some other essential oils.
Clove oil contains phenylpropanoids, a chemical component known for its stability. According to research, essential oils containing phenylpropanoids, such as clove, basil, cinnamon, oregano, and peppermint, boast a shelf life of up to three years.
Therefore, under proper storage conditions, clove oil can remain potent and effective for approximately three years.
| Essential Oil Type | Shelf Life (Approximate) | Examples |
|---|---|---|
