Over time, exposure to oxygen, light, and heat causes oxidation. Pure, volatile aromatic compounds are inherently resistant to microbial growth, so they do not have a standard "expiration date" like dairy or meat.
Understanding How and Why Essential Oils Lose Potency Over Time
When the volatile compounds in the oil react with oxygen in the air, they begin to change. However, they absolutely have a shelf life regarding quality.
Instead, they undergo a gradual chemical degradation process that diminishes their therapeutic properties and alters their scent. To slow down oxidation and preserve the integrity of the oil, you should store the bottle tightly sealed in a cool, dark location.
How Essential Oils Undergo Chemical Degradation Over Time
Expiration: It's Complicated When consumers ask if essential oils expire, they are usually trying to understand if the bottle in the back of their cabinet is still safe to use. Visual changes, such as cloudiness or sediment at the bottom of the bottle, are also red flags that the oil is no longer in its optimal state.
