Essential oils are volatile aromatic substances extracted from the flowers, leaves, stems, roots or fruits of plants by steam distillation, extrusion, cold soaking or solvent extraction. Essential oils are divided into diluted (essential oil blend) and undiluted (essential oil alone).

Essential oils are highly volatile and volatilize quickly once they come into contact with air.

Not all plants produce essential oils, only plants that contain balsam glands can produce essential oils. The distribution of balsam glands varies from plant to plant, and some are found on petals, leaves, rhizomes, or trunks. After the sachet is refined and extracted, it becomes what we call a plant essential oil.

Essential oils contain many different components, and some essential oils, such as rose, can be made from more than 250 different molecules. Essential oils are lipophilic and easily soluble in oils because the molecular chains of essential oils are usually short, which makes them very easy to penetrate and enter the body through the abundant capillaries under the subcutaneous fat.

1. Most essential oils have a shelf life, but the shelf life will vary according to the type of essential oil and the preservation method, so the shelf life of different essential oils is different, and it is important to pay attention to the shelf life on the packaging of essential oils. You need to be careful when using different types of essential oils.

2. The shelf life of citrus essential oils such as lemon, sweet orange, and tangerine is relatively short, and it is best to use it up within 1 to 2 years.

The shelf life of unopened essential oils can reach 2 or 3 years, and the shelf life of essential oils will be shortened accordingly after opening, and the shelf life of different types of essential oils is also different. The shelf life of floral essential oils is about two years, and the shortest shelf life of citrus essential oils is only one year.

The shelf life of essential oils is long when unopened, but the preservation of essential oils should be kept in a dark place as much as possible to avoid the deterioration caused by the volatilization of essential oils by air and sunlight, and the preservation of essential oils is best kept in dark glass bottles.

However, only citrus essential oils do not apply to the above preservation rules, because citrus essential oils contain terpenes, which are an ingredient that causes the oxidation rate of essential oils to accelerate, so the shelf life of citrus essential oils is only about half a year to one year. In addition, high-concentration essential oils such as patchouli or velifol oil are more mellow the longer they are stored, so it is too late to store them for a period of time before using them, so that their viscosity and purity are more refined and then used.

Therefore, after purchasing essential oils, it is best to mark the date of purchase and use of essential oils with a pen on the bottle, which can help you clarify the shelf life and expiration date of essential oils, and you can clearly understand when essential oils need to be used, so as to avoid letting essential oils expire without knowing it without paying attention.

1.Use the inside of your arm to test for mold rubber allergies. Take a small amount of essential oil drops and gently massage it on the inside of the arm, if there is redness, itching and pain and other allergies, it should not be used again.

2.Drop a few drops of essential oil in mineral water. If the essential oil is mixed with water and produces turbidity and precipitation, it means that the essential oil has deteriorated and can no longer be used.

3.Smell it. If the smell of the essential oil is noticeably different from before, it may have gone bad and can no longer be used.

In general, although essential oils have an expiration date, expired essential oils can still be used in most cases as long as they do not deteriorate significantly and are stored properly.

The shelf life of the same kind of essential oil is different, the shelf life of most essential oils is about 3 years, the shelf life of woody and resin essential oils is relatively long, and essential oils such as sandalwood essential oil, frankincense essential oil, patchouli essential oil and other essential oils also have the characteristics of longer and more alcohol.
