Essential Oil Blotter Test

Essential Oils Purity

Aromatherapy is defined as the use of essential oils, either applied topically, orally, inhalation or other means, to promote health, hygiene, and psychological well being. However, to reach the maximum effectiveness of its therapeutic properties, the essential oil used must be 100% pure and natural. This would mean that the essential oil should only be extracted from a single botanical species, not mixed or adulterated with any other substance or material. The color, texture, and scent will also vary depending on the time/season that the parts of the plant are harvested. As the trend of using essential oils are gaining more popularity in recent years, many home users are using the essential oil blotter test to check the purity of their essential oils. But how accurate is the essential oil blotter test anyway?

 

What is an essential oil blotter test

Essential Oil blotter test, also known as the white paper test, is one of the hot topics on the Internet. Many believed that it is a sure-way for  testing the purity of the essential oils. The process is quite simple. Just put a drop of essential oil on a white paper and allow it to dry up to 24 hours. The test is based on the assumption that pure essential oil will dry out without leaving any stain. You should also notice that the scent changes as the essential oil evaporates.

 

The misconception of essential oil blotter test

Blotter test only works well for oils that are clear like eucalyptus, tea tree or lavender. Oils such as lemongrass, orange, patchouli etc will leave a residue as it is naturally colored/tinted. Also, depending on the oil’s composition, different oil will evaporate at a different rate. So just leaving it to dry for a couple of hours will not be accurate for some essential oil. Heavier oils like ylang-ylang, patchouli, cedarwood, and cinnamon bark will take a few days (2-4 days) to dry out but still leaves a very faint stain on the paper.

 

It is important to note that essential oil stain is different with oil stain. As mentioned earlier, essential oils that are tinted/colored naturally will leave some residue/stain due to its color. But once evaporated it will no longer have any scent and there’s no greasy feel on the paper.  Oil stain will have the same wet-looking appearance throughout even during dry out.

 

What can essential oil blotter test do

Blotter test is merely intended to help you determine if an essential oil had been diluted with a carrier oil. If the test indicates that there’s carrier oil added and the dilution is not declared on the label, then that is a problem. However, it is not able to test whether the oil had been adulterated. To know whether the oil had been adulterated, a GC/MS lab test needs to be performed on the oil and a specialist is required to interpret the result, but that’ll be a discussion for another day. On a side note, our essential oils do come with the necessary documents that certify the purity of our oil, such as COA (Certificate of Analysis), MSDS and GC/MS. Do contact us should you require a copy or assistance with regard to the documents.
