Shelf life of essential oil
First, check whether there is a sign of service life on the bottle. If so, refer to the above instructions for identification. If not, it depends on whether the purity of the plant essential oil you buy is high. If it is marked with 100% pure prescription, the shelf life is quite long. If it is not opened, LED Diffuser it is basically about three to four years, and the shelf life of pure plant essential oil is almost the same. If it is opened, it will deteriorate within a year. Note that there is a difference between 100% pure essential oil and 100% pure natural essential oil, because the base oil is also a natural essential oil. If the pure essential oil is added to the base oil, it is still a pure natural product, but it is not a pure essential oil. The shelf life is not long. Adding water and essential oil with Aroma Diffuser can make the air fragrant and fresh.
Because of its natural bactericidal and antioxidant properties, essential oils are not easy to deteriorate, but this does not mean that essential oils can be preserved forever. Essential oils are aromatic components extracted from plants, and plants themselves are of old age, illness and death. Aromatic components also undergo a gradual change from phenols to esters to alcohols. The essential oil must be extracted in the period with the best effect on the human body. Of course, the selected stages are different according to different plant species. Therefore, it is normal for the essential oil to gradually emit fragrance during the transformation process, that is, the so-called "the older the more fragrant", but as long as it passes the stage with the best effect on the human body, the essential oil will only have fragrance left. Ultrasonic Aroma Diffuser drops some essential oil to disinfect and sterilize the indoor air. Other effects will weaken or disappear, which is the meaning of the shelf life of essential oil.
