Essential oils are known as Western herbs, plant hormones.

1. The naming rules are different.

Unilateral essential oils are generally the name of the plant plus essential oils, such as lavender extract is called lavender essential oil, lemon extract is called lemon essential oil, and rose extract is called rose essential oil.

Compound essential oils are generally named according to their functions, such as essential oils, essential oils, moisturizing essential oils, and so on.

2. **Different.

Due to the high purity and small amount of extraction, single essential oils** are generally higher than compound essential oils.

1. Ratio: Most of the pure essential oils are more than 100 yuan, and it takes thousands of kilograms of rose petals to extract one kilogram of rose essential oil, so rose essential oil is very expensive; The essential oils extracted from the peels of citrus fruits such as sweet oranges are relatively cheap due to the large number of raw materials and high oil yield.

Pure essential oils are not allowed to add any chemicals in the process of production and distillation, so ** will not be too low.

2. Look at the packaging: essential oils must be bottled in dark glass bottles to ensure its quality, because light, high heat, and humidity will destroy the composition of essential oils.

3. Observation of solubility: Because the molecules of plant essential oil are very small, they can quickly penetrate into **. Therefore, you can gently rub the test essential oil on the back of your hand and massage it a few times (when testing a single essential oil, please dilute it first and then massage it on the back of your hand), the purer the essential oil, the faster it will be absorbed, and it is not easy to produce a heavy greasy feeling.

Drops of pure essential oils float on the water and form droplets of oil that do not dissolve even when stirred.

4. Smell the fragrance: The taste of pure essential oil is fragrant and natural, and good essential oil will not have the choking smell of chemical spices.

The concentration of essential oils is very high, and it has a taste that is more than 70 times concentrated by the original plant, and the smell is natural, dull, continuous, and multi-layered. Essential oils contain hundreds of different molecules, which act on the back of the brain to make you feel the difference between the front, middle and aftertaste, and have a long aftertaste.

5. Check the transparency: pure essential oil is packed in a glass bottle, so its state can be observed through the glass, if the state presented is a clear and transparent liquid, there will be no turbidity, it is a pure essential oil. Most essential oils are not greasy or slippery, but rather clear and watery.

You can put a drop of essential oil on a tissue or white paper to observe the state of the essential oil. After the essential oil evaporates and dries, it generally does not leave oil stains. Some essential oils that contain iron may leave a yellowish brown color, and some citrus essential oils can leave a yellowish mark.

6. Test volatility: Most pure essential oils have high volatility, and you can take the test products and drop them on the paper when you buy them, which can be completely volatile and leave no oil stains. If it is not fully absorbed after a long period of massage, or leaves a shiny oil component on the **, it means that the essential oil is not pure.

1. How to determine whether a product is good or bad?

1. The packaging of aromatic essential oils with oxygen and sunlight will affect the durability of essential oil storage, so the packaging of pure aromatic essential oils is usually kept in dark dropper bottles to prevent sunlight and oxygen from penetrating. Under fairly good storage conditions (stored at room temperature), good quality aromatic essential oils can be stored for 4 to 5 years, and citrus aromatic essential oils can also be stored for 1 2 years.

2. Observe whether the aromatic essential oil contains impurities, and the aromatic essential oil pressed out of the peel by the traditional freezing compression method will leave a little residue, which will make the product of poor quality, so avoid choosing such products when fragrant.

3. The smell of aromatic essential oils is pure plant aromatic essential oils exude a natural fragrance, which is different from chemically synthesized perfumes, spices or flavors.

4. Mixing of aromatic essential oil and carrier oilWhen the pure essential oil is blended in the carrier oil, it will be completely integrated, and the molecules of the two will also be completely combined. Otherwise, the essential oil is blocked by chemical compounds or waxes and cannot be combined with the carrier oil.

2. Comparison of essential oils.

1. The origin, cultivation method, picking time, collection labor cost and extraction method of different plants are all related to the differences in different origins of the same plant. Each essential oil has its own representative origin, as it is best suited for temperature, variety, and years of harvesting experience. Lavender, for example, is recommended to be produced in Provence, France.

2. The difference in purity can drop the essential oil into hot water, and the pure essential oil will disperse into fine particles, and there will be no black viscous matter after drying. Pure essential oils are dripping on toilet paper, leaving no traces after drying, and continue to have the original fresh fragrance.

Impure essential oils dripping on toilet paper will cause oil stains, and the smell will quickly evaporate and disappear.

3. Simple test to measure purity.

1. Put a drop of essential oil on blotting paper or coffee filter paper and leave it overnight. If there is still a noticeable oil stain on the paper on the second day, then the essential oil may have been added to the base oil. Because most clear oils don't leave grease stains at all.

However, there are exceptions, such as thick sticky essential oils, such as patchouli, Wei Tiwei, etc., which may have oil stains. The same is true for some cold-pressed oils, such as citrus.

2. Put a few drops of essential oil into a clean glass bottle, add some water, shake, and wait a few minutes. If the mixture is milky white or cloudy, then the oil is most likely to be mixed with alcohol or other ingredients. Similarly, if the essential oil is already cloudy when water is not added, then the essential oil is also defective.

1. Look at the skin's reaction

The purer the essential oil, the stronger the penetration, and the stronger the ability to regulate blood circulation. Therefore, before purchasing, you can rub the essential oil conditioned with the carrier oil on the back of your hand, and then massage it with your fingertips for a few seconds, if the essential oil can be quickly absorbed without leaving traces of essential oil, then this essential oil is the best quality. On the contrary, if you can see that the essential oil leaves some oil-like components, then it is very likely that the essential oil is fake, or a lot of additives have been added, resulting in a very low purity.

2. Look at the packaging label:

Only the label "Pure Essential Oil" is 100% derived from natural plants and does not contain any synthetic ingredients. If only a small amount of essential oil is added to the product, the name of the product is only labeled as "aromatherapy oil", "aromatherapy blend", "essence", etc.

3. Look at the container:

Essential oils are volatile easily, so they must be placed in dark glass bottles to ensure the purity of the essential oils. The corrosive nature of essential oils also means that they cannot be put in bottles made of plastic. Therefore, once you find a product with essential oils in a plastic bottle, you must not buy it.

4. Smell the fragrance:

Pure natural essential oils, aromatic and pure. The smell of synthetic spices is mixed with a lot of fragrances, so if you feel pungent or uncomfortable at first smell, it is likely that the essential oil is fake. It's only possible that it smells good and doesn't get dizzy.

5. Look**. Plant essential oils are mainly extracted by distillation, generally 100 kilograms of flowers and plants can be extracted from 2 3 kilograms of essential oils, so the real essential oil ** will not be too cheap, the reference of the market ** is: ordinary essential oils such as orange, tea tree oil about 10m 400-1300 yuan, precious essential oils such as sandalwood about 10m 900-1700 yuan.

It is recommended that you go to a regular large shopping mall or professional beauty institution to buy. If some self-proclaimed imported essential oils are cheaper than domestic products, their authenticity is self-evident.

Compound essential oil is a blend of more than two single essential oils and base oil, and its effect is generally its name! Can be used directly.
