The key of buying essential oils is to consider two factors: 

First, the purity, that is about the technology of extract and purify; 

Second, the proportion of dilution. 

You can refer to the following method to purchase better oils.


The plant essential oil is mainly extracted by distillation. Generally, 100 kilograms of flowers and plants can be extracted 2 to 3 kilograms of essential oils. Therefore, the general price of real essential oils are expensive. It is recommended that you purchase them in formal large-scale shopping malls or professional beauty institutions. 


Except for a few varieties such as rose, tea tree, lavender, etc., the majority of pure essential oils are not applied to the skin directly, otherwise it will cause burns, peeling.The difference between base oils and essential oils must be distinguished. Some base oils in the name of essential oils are indeed deceived by many people.


Most pure essential oils are soft and mellow, because they are 100% extracted from plants, so pure essential oils have an indescribable taste of natural plants (although the smell is not necessarily good smell). When you smell it at the first time, the taste is not very strong, but there will be an aftertaste and there is a kind of wilderness feeling in the back of the brain. Everyone feels differently about it. Top notes, middle notes, and base notes are different.


A. After the essential oil is smoked several times, if a greasy residue (different from waterlogging) is left, it means that it is diluted with vegetable oil or mineral oil; if the crystal substance is left behind, it is likely to be diluted with ethanol and ether, it maybe harmful to health for long time usage.

B, Add a drop of essential oil into a glass of water, the real pure oil generally volatile quickly and no residue left. If diluted with vegetable oil or mineral oil, the evaporation rate will be much slower, often leaving oil on the water surface.


Essential oils are usually stored in dark-colored sealed small glass bottles. They have special acid-resistant, alkali-resistant bottle caps to prevent sunlight and oxygen from penetrating, so that the essential oils are not volatile and deteriorate. In a good preservation environment (stored at room temperature), it can usually be kept for two years. The good quality oil can be stored for 4-5 years. Citrus essential oils can also be preserved for 1-2 years. Products packed in dripper-equipped bottles are typically between 3% and 10% diluted essential oils, not pure essential oils. The label of pure plant essential oil should be marked with purity.


In general, the proportion of grass essential oils is the lightest, drops into a glass of water will quickly spread out, the water surface will show an oil slick; resin the heaviest molecular molecules, drop into a glass of water, can drop a full drop into the cup At the end, it should not be soluble in water. But both of them will be under the surface of the water, and they will distribute two types of essential oil molecules. Although they are insoluble, they have not filled the whole glass of water. The special citrus oils in flower oils are heavier than water, and they are insoluble in water. Similar to resin oils, they drip straight into the bottom of the water to see crystal-clear dark green oil beads.


For example, the German Ocean Citrus, because it contains a very precious ingredient "blue scripture", the color is dark blue, with a strong smell of medicine.


The more refined and pure the essential oil, the stronger the penetration. Wipe the test oil gently on the back of the hand or inside the wrist, then massage it a few times with your fingertips. Good quality essential oils are absorbed instantly and do not leave sparkling oils on the skin. You can also see if the essential oil contains impurities. For example, the essential oil that is pressed from the peel by the traditional frozen press method will leave a little residue, which will result in poor product quality. Because of the molecular structure, the volatilization rate of essential oils is relatively fast, and it can be played within 5-10 minutes, which means that the essential oils are relatively pure. The very slow evaporation is not necessarily a pure essential oil.


Pure essential oils are highly lipophilic, and when blended in a base oil, they will be fully fused and the two molecules will be fully integrated. Otherwise, the essential oils contain chemicals or waxes that cannot fully blend with the base oil.

Place of Origin

Plants that extract essential oils will have different qualities depending on the place of production. Land quality, air temperature, humidity, planting standards, harvest time, and treatment methods all have a direct impact on the quality of their essential oils. Therefore, attention should be paid to the origin of the plant when you selecting the essential oil.

Hope these tips works for you if you need to choose essential oil.
