1. What is agarwood essential oil?
Frankincense essential oil is an essential oil compound of frankincense that is condensed without mixing any other impurities.
Currently on the market there are 3 methods for the essential oil to ejaculate, but now I can only remember 2: steam distillation method, the liquid critical method of CO2 extraction. (will add more)
2. Identify pure agarwood essential oils
The most accurate way to determine if the agarwood essential oil you buy is pure is to have it checked by an institution. However, that method for customers who buy small quantity is completely not positive.
The method I give here is going to be easy and anyone can do it with. That is to add the essential oil solution to the water.
Understand that "most" essential oils have a lighter density (M) than water. So when the essential oil is poured into water, it will float, suspended or submerged, depending on its density.
This test will not help you know if the oil is impurities, but it can tell you if there is more than 1 type of essential oil in the bottle because the specific gravity of each type is different.
What you need to do this test:
Essential oils need to do experiments
Small glass bottle
Country
Step 1: Pour water into 3/4 bottles or small glass tubes (transparent for easy viewing).
Step 2: Put 1 drop of oil into the glass bottle and cover.
Step 3: Shake the bottle of essential oil and water mixture vigorously.
Shake vigorously for about 10 seconds then you will find it interesting. The large drop of oil has split into many smaller oil seeds.
Then leave it there and start watching. Here are the possible results.
Case 1: There is only 1 essential oil contained in the bottle.
Initially, the mixture was still cloudy, small oil particles began to float and stay above the water.
After completely settling, you will see the oil float completely on the water and stick to the wall of the glass jar. At the same time the aqueous solution is clear.
Case 2: The mixture is still cloudy, there are some small particles connected, some sink and some are suspended in the middle.
There appear 4 interesting parts in this experiment.
1: On the top of the tube you will see some opaque substances sticking to the opaque white wall.
2: Oil droplets floating on the water.
3: The drops of oil are hanging in the middle.
4: The drops sink.
Each case is different, but we cannot determine what these four separate layers are, but we can determine that the above sample is not a homogeneous essential oil, but a mixture of many types.
After 5 hours, the oil seeds sink and the suspension started to float and stick together to form an inverted peak. But still appears the translucent compound sticking on the top of the glass bottle.
Bottom Line: This essential oil sample is not pure frankincense.
Case 3: Transparent mixture, there are many bubbles emerging on the top then disappear gradually.
Conclusion Agarwood essential oil contains "coconut oil fraction"
Case 4: The mixture is transparent, the small drops float and form a homogeneous mixture, a little bit cloudy on the bottle wall.
This model contains a lot of agar oil, but there are 2 types of oil that are blended together. One is bass oil, the second is not.
Case 5: The oil particles floating on the water surface stick to the wall of the bottle, the water is still cloudy.
This is often the case, since the sedimentary oil has been diluted with solvents to increase the volume of the essential oil.
Case 6: Transparent mixture, 3/4 submerged essential oil, 1/3 floating essential oil.
This is a sample of agar oil that is extracted by the liquid CO2 method (CO2 is pressed with very high pressure will return to the liquid state). Before doing this experiment, I had predicted that this oil would sink into the water with a mass of 1.03 grams / 1 ml and of course it was heavier than the density of water (MH2O = 0.997 grams / 1 ml).
Interestingly, when the export of the same material is crushed frankincense into powder, there are two types of essential oils that can sink and float in water.
For example, from ginger, which is extracted from supercritical CO2, all float on the surface of the water.
Why is the capacity by CO2 like that?
Below is the verbatim excerpt translated into Vietnamese.
When its density is heavier than water, it sinks.
To find out more, I asked Dr. WS, who replied: "As oil resins have different (length), the materials (older) the oily resin tends to sink, during the distillation process. By steam or hydrogen you get mostly volatiles or short chains simply because it is light so it is easy to carry, and by the CO2 method it will pull and squeeze longer structural chains, especially in supercritical level. "
3. End the test.
1. Pure agarwood oil: This is our product sample given for testing.
Claimed to be pure agarwood oil but it is not, it contains more than 1 essential oil.
3. The mixture of agar oil and fractionated coconut oil
Claimed to be pure agarwood oil, it still has a little bit of turbidity on the surface so it has more than 1 pure agarwood oil.
5. Frankincense oil sticks to the bottle, but the water is not clear: Frankincense oil has been diluted by a solvent dedicated in cosmetics (this solvent is water-soluble, so it is cloudy).
6. As the pure frankincense essential oil exported by CO2 method, this method obtained 2 essential oils which, as Dr. DW explained, this method obtained 2 kinds of long chain essential oils (density larger than water) and short chain (density is less than water) so as in the above test you will see 1 type submerged under water and 1 type floating in the water, but the water is still clear, not appearing cloudy.
Thanks for reading our analysis, hopefully it will help you understand more about agarwood essential oil
