How to store essential oils?

Since plant essential oils are completely extracted from plants, without any addition, filtration or artificial synthesis process, their chemical composition is very susceptible to deterioration by air, light, temperature, humidity, etc. It is best to store essential oils in wooden boxes. Such as sandalwood or pine boxes. Therefore, pure essential oils are usually stored in dark glass bottles, preferably below 18 degrees Celsius. High temperature will cause the chemical composition of essential oils to change.

There are many plant-derived products in daily life, the more they are released, the better. For example, “wine” can be more fragrant as it ages, and plant essential oils are also the same principle. As they age, the fragrant will be more fragrant. Therefore, over time, the organic ingredients, such as alcohols, enes, acids, etc., will polymerize into aromatic esters. This is the case for wine. The same is true for essential oils.

Generally speaking, after the plant essential oil is opened, it depends on the time and area of ​​contact with the air, and the loss rate of some of its volatile molecules. Most of the time, such as the more intense and highly volatile essential oils: eucalyptus essential oil, tea tree essential oil, basil essential oil, rosemary essential oil, after opening more times, it will present a sweeter taste, not the spicyness of the first opening. The transformation of taste cannot be said to be bad.

Take eucalyptus oil CAS 8000-48-4 as an example. Eucalyptus oil is widely used in daily chemical, perfume, medicine, food and other industries. The main uses are as follows: used in medical treatment, medicine, oral care, with antibacterial, anti-inflammatory Chemicalbook, and antioxidant effects; used in sanitation, with anti-mold, insect repellent and mosquito repellent effects; used in agriculture and animal husbandry production In terms of insecticide, feed additives or animal health products additives.

For Kaifeng essential oils, its shelf life is different. For example: Fruits have a shelf life of half a year after opening; grasses should be within one year after opening; flowers should be within one year to two years after opening; wood should be within two years after opening; resins and spices are less restricted. However, it is still based on two years after Kaifeng.

Essential oils must be stored in dark glass bottles with shading effect, which can reduce 90% of ultraviolet radiation. Do not store essential oils in plastic bottles. The chemical composition of plastics will destroy the quality of essential oils.
