Understanding Essential Oil Oxidation
The integrity of essential oils is paramount to their efficacy in aromatherapy practices. However, the moment an essential oil bottle is unsealed, it becomes vulnerable to an oxidation process that leads to a series of essential oils chemical changes. Oxygen initiates these changes by altering the bonds within the oil’s molecules, converting oxygen bonds to carbon, which can reduce the oil’s potency and therapeutic qualities.
Awareness of proper storage conditions is critical to preserving essential oil quality and longevity. Experts recommend storing these volatile compounds in UV protection bottles, typically made of dark amber glass, to act as a barrier against the deteriorating effects of ultraviolet light. These protective measures collectively help in maintaining the oil potency over time and are a testament to the industry’s standards for prolonging the usability of aromatic oils.
Signs that an essential oil has undergone detrimental oxidation include a noticeable alteration in the aroma—a scent that is either too sharp or noticeably faded—a visible change in color, or the consistency becoming either unusually thick or thin. Once these signs are apparent, it is often advisable to discard the oil as it may no longer offer the desired benefits and could potentially cause harm if used.
- Keep essential oils away from direct sunlight and heat sources.
- Always tightly seal the cap after using the oil to prevent prolonged oxygen exposure.
- Consider transferring the oil to smaller containers as the volume in the original bottle decreases.
