How should essential oils be stored to maintain their efficacy?

Essential oils should be stored in tightly sealed containers in a cool, dark place to maintain their efficacy. This storage method is important because essential oils are volatile compounds that can degrade when exposed to heat, light, and air.

Storing essential oils in a cool environment slows down the evaporation of the oil and minimizes the risk of chemical changes that can occur at higher temperatures. A dark place protects the oils from UV light, which can break down their chemical structure and diminish their therapeutic properties. A tightly sealed container prevents air from entering, which can also lead to oxidation, further compromising the quality and effectiveness of the oils.

While glass containers are preferred for essential oil storage as they do not react with the oils, the primary factors for maintaining efficacy are temperature, light exposure, and air contact. Thus, the combination of tight sealing and careful placement in a cool, dark environment is crucial for preserving the integrity of essential oils.
