NOW Essential Oil Identity & Purity Assurance (source: www.nowfoods.com)
Essential oils are pure reflections of the botanicals from which they’re derived, but their production is an extremely complicated process with a multitude of variables, each of which has a significant impact on the quality of the final product. Raw material supply is one of the most important of these variables. Over the years NOW® Solutions has established long-standing relationships with many of our growers, which help us assure the quality and availability of the raw materials used for our essential oils. However, factors such as global market conditions and unanticipated weather events can affect the supply of certain oils from year-to-year and even season-to-season. As with many natural products, when supply is constrained there is concern regarding quality. Over the years we’ve seen examples of dilution, substitution, and even the use of synthetic alternatives masquerading as their natural counterparts.
So how does NOW Solutions consistently assure the identity and purity of our essential oils? How do we protect retailers and consumers and ensure they’re getting the product they paid for? We utilize state-of-the-art testing and analysis as well as numerous checks and balances, including:
- Identity and purity testing
- Use of The Essential Oils compendium by Ernest Guenther, Ph.D. and Fenaroli’s Handbook of Flavor Ingredients, edited by George A. Burdock, Ph.D., to verify the correct essential oil species
- Supplier/grower track record of providing high quality materials
- Aroma comparisons
- Review of essential oil processing to ensure that appropriate extraction methods are used
- Appropriate cautionary and regulatory language
Because identity and purity are key attributes of any essential oil, testing for these attributes is the best way to ensure an oil’s quality. At NOW Solutions our identity and purity testing program consists of four individual tests.
1. Gas Chromatography-Mass Spec (GLC-MS)
This sophisticated analytical technique utilizes specialized technology to separate an essential oil into its components for analysis. Our chemists take the results of the Mass Spectrometry analysis and compare them with a standard analysis for the specific oil being evaluated, carefully noting the presence and ratio of key identifying components and unique markers. Components and markers not present will indicate oil from an incorrect species, and components not normally present will generally indicate adulteration with other less expensive essential oils, fragrance compounds, plasticizers and the like. NOW owns and operates several gas chromatographs, with an entire in-house laboratory devoted to this method of analysis.
2. Fourier Transform Infrared Spectroscopy (FTIR)
Another sophisticated analytical technique we utilize is infrared spectroscopy. For this analysis, a sample is scanned with different Infra-Red frequencies which energizes the chemical bonds in the sample components causing them to vibrate. Every compound has a different vibrational pattern (called spectra) due to its distinct bonds, and this pattern serves as a “fingerprint” for the material being tested. Each essential oil will also display a characteristic spectral pattern. Highly trained chemists compare the spectra of the sample against standard spectra for that essential oil to ensure its identity. Abnormal spectral patterns will indicate the presence of adulterants. Although the two techniques are vastly different, when used together, gas chromatography-mass spectrometry and infrared spectroscopy provide incredibly powerful assurance of identity and purity.
3. Refractive Index
Refractive index is an analytical technique in which light is passed through a thin layer of sample sandwiched between two agate prisms. The degree to which the light is bent or “refracted” is measured and then compared to the value for the reference material, in this case the essential oil. Each essential oil will refract light differently due to their unique chemical composition, so the difference will indicate not only the identity of the substance but, more importantly, if the oil is pure. An essential oil that has been diluted with other substances would display an unacceptable variance in refractive index. Refractive index is another analytical technique used to confirm the identity and purity of the essential oil.
4. Specific Gravity
This relatively simple analytical technique compares the density of a material sample to a reference sample for the purpose of verifying identity. Certain types of adulteration will result in a unacceptable variance in specific gravity, allowing our technicians to further determine the identity and purity of an essential oil.
The combination of gas chromatography-mass spectrometry, infrared spectroscopy, refractive index, and specific gravity, and the ability to perform these sophisticated tests in-house and on-demand, provides NOW Solutions and our customers with powerful assurance of the identity and purity of our essential oils. These tests are performed on all of our essential oils.
Combining the results of all these techniques enables the chemist to achieve a complete characterization of the essential oil.
Food Grade and Therapeutic Grade
We’re often asked if our essential oils are edible, or “food grade”. All of our citrus oils, and other specific edible oils, are from edible plants. If you recognize the source of these oils as food (i.e. peppermint, oregano, cinnamon bark), then natural extraction methods such as steam distillation and cold pressing do nothing to change this quality, and these methods do not make the oil toxic. However, in order for us to claim an essential oil is food grade we would have to sell the oil as a food product and include a Nutrition Facts panel on the label, as required by law. Brands that claim their essential oils are food grade should display a Nutrition Facts panel on their label.
Our oils are intended for aromatherapy and are labeled as such. Additionally, we include cautionary language created by the American Herbal Products Association (AHPA) intended to protect consumers from misuse of the product. Some presumably food grade oils do have specific cautions against internal use that should be followed. Please note that our essential oils are highly concentrated and thus caution should be taken if you consume them. Oils that are not food grade will have the statement “Not for Internal Use” in the caution box on the label. If you have questions regarding the use of any NOW Solutions essential oil please contact our Certified Nutritionists by calling 888-669-3663 and choosing option 5 or by emailing firstname.lastname@example.org.
Therapeutic-grade essential oils are oils that a third party pharmacopeia or other statutory organization has (supposedly) created monographs for, which can be used by any brand as a measure of quality. We’ve reviewed the information regarding this grade and have concluded that “therapeutic grade” is just a marketing term used by some brands, with no authoritative body or organization behind the term.
