If you look for the criteria for judging the quality of essential oil from the Internet or books, one of them must be to look at the label to judge the origin, extraction method, main chemical components, varieties marked in Latin and so on.

But the label is only a reference, and the quality needs your own judgment. For example, individual brands not only labeled all the above information, but also labeled spectral analysis, but the quality of my actual experience was not enough.

Each essential oil has its own characteristics, and some have some identification methods, but it needs professional aromatherapy knowledge.

For example, if there is a bad manufacturer of happy sage, it will be replaced by sagebrush. You can put it on perfume paper and smell it after 24 hours. Happy sage is not volatile, because it contains macromolecular diol, and it still has a taste after one day, but sagebrush does not contain this ingredient. For another example, the main component of lemon and sweet orange is small molecular monoene, which volatilizes quickly. If the volatilization is slow, you will question its quality. Pay attention to the difference between lemon and lime. The more sour lemons taste, the better. Lime is a little sweet.

In fact, the best way to identify it is how your body feels. Beginners are strongly advised to use the highest quality oil you can buy first (recommended by international brands such as Profant German Crescent Tisserland), and oranges must be organic. After your sense of smell and body remember what high-quality oil looks like, try to choose other brands or channels, and you will have the ability to distinguish. This is an expensive process.

I now use oil mainly in three ways:

1.Profang uses foreign brands most, relying on purchasing. In fact, the quality of the recommended foreign brands you can find is not bad. The key is that the purchase channels should be reliable and there are many fakes. I bought it in a treasure about 10 years ago. It's not fake, it's diluted oil. The focus is on this store, but it's still open ... Novices must not be greedy and cheap without discrimination!

It makes sense that the value for money, such as AZ NG, is not recommended for aromatherapy and soap making. It is also organic lemon, but the price ranges from 20 to 30 to 80 to 90. If you know the origin and output, you will know that the lemon essential oil in Mexico is mostly a by-product of lemon juice, so the cost will be much lower and the quality will be different.

2. If you have a certain ability to distinguish the quality of essential oil, and the quantity is large, you can find a reliable supplier of essential oil raw materials. Recommended channels: Alibaba Li Po and Park Jin International, no matter where you get the goods, you can try 3ML samples, but the samples are all in transparent bottles and need to be taken back in hidden bottles.
