Essential Oils: What’s Really in that Bottle?
Marketing hype or Myth??
One of the very first lessons I learned in my aromatic journey was 'know what to ask for'. Being curious, I asked, ‘what exactly does that mean?’ The reply (from my professor at Purdue, Jim Simon, currently at Rutgers)… “Know how to identify what it is you want to purchase”.
Even today, when some customers call, they are still not educated on what are the differences between essential oils, absolutes, resins, carrier oils, infused oils or fragrance oils. Allow me to shed some light on this.
* Essential Oils:
An essential oil is a product obtained from natural raw material, either by: distillation with water or steam or from the epicarp of citrus fruits by mechanical processing, or by dry distillation. They are concentrated extracts and should never be used ‘neat’ (directly) on the skin.
Essential Oils are found in:-
The flowers, leaves, bark, wood, roots, entire plant or fruit peel.
* Vegetable Oils (Carrier Oils):
Vegetable oils work to benefit skin and health. They are produced from nuts and seeds, producing oils, butters and fats.
For example: Sweet Almond, Sesame Seed, Shea butter, etc.
Essential oils are typically blended with some type of Carrier oil before applying to the skin or a skin care product.
* Fragrance Oils:
Fragrance oils are made out of synthetic material. This came to pass because an essential oil scent would vary from year to year depending on the weather conditions. (Too much rain, too little rain would stress the plant which would effect the scent). Especially for the perfume industry, they needed to ensure that the scent was identical every time they produced a fragrance.
More and more the trend today is to ‘go back to basics’. This is one of the reasons why Natural Perfumery is making such a big come back.
So, you’re looking for a certain essential oil?
No worries... Just be sure that the following basic information is on the bottle:
- Essential oil: Lavender
- Botanical Name: Lavendula angustifolia
- Country of Origin: France
The ‘botanical name’ and ‘country of origin’ are what identify the essential oil you are looking for, it’s 'fingerprint' if you will.
Lavender - Country of Origin could be France or Bulgaria
Rose Otto - Country of Origin could be Bulgaria or Turkey
Vetivert - Country of Origin could be Haiti or India
The scent will vary due to country of origin.
Rose Absolute Morocco - Rosa centifolia
Rose Absolute Bulgaria - Rosa damascena
The above not only have different countries of origin, but also have different botanical names, be sure to identify the product you are looking for as it will affect the scent of these materials.
Some essential oils have many subspecies - i.e.:
Eucalyptus citridora (this has a lemon scent)
Eucalyptus globulus (the most common)
The examples above show - ‘what you want’, ‘what is in the bottle’ and knowing the botanical name is crucial.
Which 'chemo type' do you require?
Depending on the properties you desire, you will need to understand the composition of the essential oil. The ‘chemical constituent’ or the three (3) major classes of essential oil constituents:
* monoterpenes and their derivatives (monoterpenoids)
* phenyl propane derivatives
* sesquiterpenes and their derivatives.
We can get into some chemistry here, however, for the purposes of this article this is an overview. It would be advisable to get to know the different properties and why you would choose them.
For a little overview:
Essential oils with Linalool are found in coriander seed, lavender, clary sage, and linalool chemo type of thyme.
Properties associated with monoterpene alcohols:
• strong antibacterial, antifungal and antiviral properties
• vasoconstrictive properties i.e. menthol, linalool, geraniol can make the site of application feel cold.
• Tonic and general stimulant properties
• Sedative properties
Properties associated with sesquiterpene alcohols:
• Antiviral properties
• Farnesol found in i.e. rose and chamomile is an excellent bacteriostatic. It is well suited to skin care and deodorant products, as it is know to inhibit, rant than kill, growth of bacteria.
• Tonify muscles and nerves
Properties associated with phenols:
• very powerful antimicrobial properties
• skin and mucous membrane irritants
• general tonics and stimulants
• stimulants to the immune system.
Marketing hype or Myth?
We are all in the business to sell our essential oils. However, there is much marketing hype that exists. When you see: aromatherapy grade, therapeutic grade, etc., to the best of my knowledge, there is no such grading system in
What else would be helpful in purchasing your essential oils?
- Distillation date – when the material was actually distilled. Some essential oils have a longer shelf life then other. Be sure to store properly (cool, dry, dark areas) and tightly close the cap to extend shelf life.
- ‘Batch’ or ‘Lot’ number is important if there is an issue with the order. However, not always available. This way the seller can pinpoint the batch and identify it more readily. (If this is not available, the distillation date will help).
- Organic – You should be given the certifying program (i.e. Ecocert, NOP, etc). This may vary from country to country.
Some customers prefer only organic, other have no preference at all. Cost is a factor, due to organic oils being more costly. (do to all the strict farming laws and paper work).
As a side note: I would prefer all citrus to be organic if possible. The oil for this is cold pressed from the rind where the pesticides are sprayed.
The key is to be an informed buyer.
- Read the labels
- Essential oil & Botanical Name
- Country of Origin
- Organic / wild crafted / conventional
- Lot or Batch Number
Start a sample box. Samples are important to compare different country of origin, and different suppliers. As well as different years. I have aged Patchouli from 2000 that is wonderful, as you know; some oils just get better with age.
Breathe in the wonderful aroma and know that you 'get what you ask for'.
