- Quality & Chemistry
The purest essential oil is one that has been harvested and extracted using the correct methodology. A pure oil maintains a level of chemical composition that is within a certain acceptable range that would rule out adulterations of any kind.
The Quality of an oil is gauged from therapeutic viability and aroma profile (organoleptic properties). In the most extreme example an oil could potentially be entirely synthetic and adulterated but still be considered higher quality then the pure form of that oil.
At EOW we look for the marriage of purity of an essential oil and the quality of an essential oil.
The purity and quality, and hence the therapeutic efficacy, of an essential oil is much more nuanced than most essential oil companies will have you believe. Many of the differences in composition are very easily explained from one distillation batch to another. If all the parties involved understand these differences the customer will have a greater understanding of the choice that they have when purchasing a desired oil.
The atmospheric pressure and soil composition directly affect the chemical components of an oil. The plant will naturally utilize different compounds to adapt to its surroundings, for example if a wild Lavender plant was harvested in the mountains it would chemically look different when compared to a Lavender that was harvested at sea level.
Another potential variance that affects chemical components is the weather or season for that particular harvest. This comes about mostly from temperature changes and moisture differences in soil. Another parameter that affects oil quality is the human element. Humans will sometimes unintentionally vary the time during the extraction process (time it takes from extraction to bottling). The time to bottling greatly changes composition in some cases, for example the timing on Rose Otto oils is extremely sensitive and can cause large percentage swings in citronellol and other constituents of the oil.
At EOW we don't see these parameters as problems at all, we see them as important components that help us arrive at a place where we can choose the perfect oil for a given harvest cycle. With all of these parameters in mind we test for chemical composition ranges and if a value may seem “out of whack” we begin then assess if this is due to adulteration or totally normal changes due one or more of the variables described previously.
Choosing the highest quality of an essential oil is understanding all of these parameters and ensuring that the best parts of an oil's chemical composition is present. Here at EOW we like to be transparent and show all of our oils constituents and have our customers choose which oil is best for their specific situation. We believe in finding the highest quality oils by constantly monitoring all of the factors that go into truly great products.
