Essential oils are affected by extremes of temperature, daylight, air and damp. They can also corrode materials such as plastic and rubber. This is why Absolute Aromas packages their essential oils in sealed, dark-glass bottles with integral droppers so that the chance of spillage is reduced. After purchase, they should be stored upright, at a steady temperature, away from sunlight. Absolute Aromas stocks a range of wooden boxes, which are ideal for storing your essential oils at home, as well as carry cases for therapists and those on the move.
