What to Look for When Buying Essential Oils

by | Mar 26, 2021 | Aromatherapy 101, General

Some of the most commonly asked questions I get and see online are: “Is this a good essential oil company?” or “Is this a pure oil?” While there is no way for anyone at home to be absolutely certain about the quality or purity of an oil, there are general guidelines that can be followed to immensely increase your chances of purchasing a good oil. In addition to our knowledge of who is well-known for being reputable in the industry, the following are many of the things qualified aromatherapists keep in mind when we are assessing a company and their products.

 

Important Points to Remember

  • Just because an oil states that it is 100% pure, does not mean that it is! This has been proven numerous times by analyses performed by chemists that specialize in essential oil analysis, some of which can be found here and here.
  • There is no regulating/independent body that determines essential oil grades. Therefore, if oils are said to be “Therapeutic Grade”, “Perfume Grade”, etc., know that these are not industry standards. They are only standards decided on by that particular company or individual.
  • Purity does not equal quality, and only pure, high quality oils produced for the aromatherapy industry should be used. Avoid anything labeled as anything less than that, such as fragrance oils.
  • Oils do have a shelf life that varies depending on the particular oil. This is something else to keep in mind when deciding where to purchase from. Do the sellers know how to properly store the oils and rotate them so that you are not getting a bottle of already oxidized oil? At best oxidized oils will have diminished effects. At worst they can cause serious adverse reactions.
  • It is recommended that you do NOT buy oils from internet marketplaces or anywhere other than the actual company or qualified distributor that sells the oils. It is very easy for someone to adulterate, tamper with, and even knock off a known company’s oils. Also, replacement tamper-evident caps can be purchased easily for just a few cents a piece and used to recap the bottle so that it looks like it has not been previously opened. Please only buy from trusted sources.

 

Key Details to Look for on the Bottle and/or Website

  • Common name and complete latin botanical name including chemotype (ct.) if applicable
  • Plant part used
  • Country of origin
  • Method of extraction/production (Is it an essential oil, absolute, CO2, etc? If an essential oil, is it steam distilled, hydrodistilled, or cold pressed? For example, if the company claims it is a pure essential oil and calls it a CO2, that is a major red flag. EOs, absolutes, and CO2s are not the same thing and a reputable company will not make that mistake.)
  • Contents of bottle (Should indicate if it is a pure single oil, diluted in a carrier, etc. If a blend, it should list all oils in the blend.)

All of these things are very important as the chemical composition is different for each of these aromatic materials, which also may affect its usage safety guidelines as well as aroma. For example, cold pressed/expressed Lime is phototoxic and can cause burns when it is applied topically and exposed to UV light, but steam distilled Lime is not.

Another example using phototoxicity is Orange. Expressed Sweet Orange (Citrus x sinensis) peel is not, but expressed Bitter Orange (Citrus x aurantium) peel is. Neither of which should be confused with the oil produced from the leaves (Petitgrain) and the flowers (Neroli).

There are also examples like Thyme ct. linalool which is much milder in chemistry and aroma than Thyme ct. thymol, which must be diluted much more than the linalool chemotype when used topically. You also do not want to confuse oils like Cinnamon Bark with Cinnamon leaf essential oil.

Then there are the suppliers that do not even know the difference between an essential oil and a lipid (carrier) oil. The last thing you want is someone who is not educated enough about what they are supplying, to get it wrong when they are selling these types of products.

 

Additional Things to Consider

  • How are the oils packaged? (They should be in glass bottles without a rubber dropper top. Pure oils will deteriorate these droppers and they will ruin the oils left in the bottle so NO reputable essential oil company will ever package pure oils this way.)
  • All oils should not be the same price.
  • Are the prices in line with other reputable companies? Are the prices too good to be true or extremely overpriced? (Keep in mind that average commercial pricing where pure essential oils are produced and sold in large amounts to thousands of people will be different than Artisan made oils that are produced in much smaller quantities and are usually a few liters at most. They are produced with keeping the oils at the highest quality possible in mind, and most times yield is sacrificed due to this. Artisan producers and sellers usually cannot meet these averages due to production size and quantity levels. As with any small business, it is not uncommon to see higher prices in these cases.)
  • What do you know about the supplier? How long have they been in business and what is their education and qualifications in the field? For example, is the company owned by or does it have a qualified aromatherapist on staff?
  • Do they provide quality safety information for the products they sell and do they promote safe usage?
  • Do they provide batch specific GC/MS information either on their website, or by request, that are performed by a reputable 3rd party lab?
  • Do they sell oils from threatened and endangered plants? If so, are they CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) certified?
