Are doTERRA Oils Pure?
The purity of an essential oil is its most important characteristic. When an essential oil is adulterated or contaminated, it becomes less effective and can even be dangerous. Above all else, purity is doTERRA’s first priority when producing essential oils.
How Does doTERRA Make Sure Their Essential Oils Are Pure?
From the beginning, we’ve made it our mission to share pure, quality essential oils with the world. However, without a definitive standard for essential oil purity, doTERRA decided to set the standard for purity in the essential oil industry.
Not all essential oil companies choose to enforce high testing standards for their oils. In fact, many companies skip important steps in the testing process in order to save money or time. Unfortunately, when proper testing measures are not taken, it’s impossible to ensure that an essential oil is truly “pure.”
To ensure that each bottle of essential oil is pure and free from contaminants or synthetic fillers, doTERRA created the CPTG Certified Pure Tested Grade® protocol. The CPTG process includes a rigorous examination of every batch of oil, along with third-party testing to guarantee transparency.

Why Is It Important to Use Pure Essential Oils?
Some people ask, “Does essential oil purity really matter?” Or, “What happens if I use essential oils that aren’t pure?”
The answer is yes—essential oil purity matters. If you use an oil that has been adulterated, contaminated, or loaded with synthetic fillers, you will not receive the full natural benefit of the plant. And in some cases, low-quality oils can even be dangerous and pose serious threats to your health.
This is why doTERRA cares so deeply about essential oil purity. If you use an impure oil, it can be difficult to feel the benefits of the oil and can possibly put your health at risk. However, when you use pure, unadulterated essential oils, they’ll be more effective, and you can stay within the bounds of safe use.
How to Know If Your Essential Oils Are Pure
How can you tell if your essential oils are pure? Before you buy essential oils, do a little research to find out how essential oil companies source, produce, and test their oils.
Here are a few questions to ask during your research:
Plant quality: Does the company use high-quality plants to produce their essential oils? Are the plants grown in the right conditions with the right farming practices?
Production practices: Does the company have safety procedures in place to guard against contamination during the production process? Are oils adulterated or are synthetic fillers added to cut costs?
Testing methods: Does the company test each batch of essential oil? Is impartial, third-party testing used? Are test results available to the public?
Storage and handling: Are the oils carefully processed, packaged, and stored to avoid chemical alterations caused by exposure to heat or light? (Amber bottles are typically the best option for essential oil storage.)
Ensuring Essential Oil Purity: The CPTG Process
doTERRA begins the CPTG testing process shortly after distillation, when each oil is reviewed for its chemical composition. The doTERRA production facility carries out a second round of testing to ensure that the oils distilled and tested during the first round are the same ones that arrived at our facility. A third review of the chemistry of the oils is conducted as the oils are packaged into the bottles before they’re shipped out to consumers.
Each test confirms that our essential oils are free of contaminants and that no unexpected alterations occurred during production.
8 Ways to Know That doTERRA Essential Oils Are Pure
The CPTG quality testing process includes eight main steps to guarantee that every batch of doTERRA essential oil is pure, unadulterated, and safe for use.
Here are the tests doTERRA uses to ensure essential oil purity:
Organoleptic testing
Microbial testing
Gas chromatography
Mass spectrometry
Fourier-transform infrared spectroscopy (FTIR)
Chirality testing
Isotopic analysis
Heavy metal testing
Using organoleptic testing to detect essential oil purity
Organoleptic testing involves the use of our human senses, specifically sight, smell, taste, and touch. To expert distillers, the senses are used as the first line of quality testing to provide immediate clues as to the acceptability of a product. An oil that has an unusual smell, uneven consistency, or strange color instantly tells the distiller that something is wrong. Often times, this testing is used as a preliminary quality control step before any other tests are conducted.

sing microbial testing to detect essential oil purity
Microbial testing involves analyzing a batch of essential oils for the presence of biohazardous microorganisms, such as fungi, bacteria, viruses, and mold. The process involves drawing a sample and then adding that sample to a sterile growth medium in an enclosed dish or plate. The sample is incubated for a period of time and then observed for microbial growth. This test is performed on product entering the manufacturing facility and on finished products prior to distribution to ensure that no products have been contaminated during the filling process.
Using gas chromatography testing to detect essential oil purity
In gas chromatography, an essential oil is vaporized and passed through a long column to separate the oil into its individual components. Each component travels through the column at a different speed, depending on its molecular weight and chemical properties, which are measured as it exits the column. Using this testing method, quality control analysts can determine which compounds are present in a test sample.
Using mass spectrometry testing to detect essential oil purity Mass spectrometry is used together with gas chromatography to further determine the composition of an essential oil. In mass spectrometry, the constituents previously separated by gas chromatography are ionized and sent through a series of magnetic fields. Using molecular weight and charge, the amount of each constituent can be identified, providing additional insights into the potency of an essential oil.
Using Fourier-transform infrared spectroscopy (FTIR) to detect essential oil purity
Fourier-transform infrared spectroscopy (FTIR) is conducted to ensure the potency and consistent quality of a batch of essential oil. This testing method identifies the structural components of essential oil compounds. In an FTIR scan, infrared light of different frequencies is shined through a sample of essential oil and the amount of light absorbed by the sample is measured. The quality of the sample is determined by comparing the results from an FTIR reading to a historical database with absorption patterns of high-quality samples recorded.
Using chirality testing to detect essential oil purity
Chirality, a term derived from the Greek word hand, is a term used to describe the 3D orientation of a molecule. Just as you have two hands, chiral molecules exist in two forms, distinguished as either the right or the left hand. You may visualize this principle by looking at your hands: when placed side by side, they’re mirror images of each other. In molecules, each “hand” has different chemical properties, which affects their physiologic interactions in the body. One hand is produced predominantly in nature. However, in a laboratory environment, the ratio of right- to left-handed molecules is always 50/50 because of their structural similarities. The ratio of right- to left-handed constituents can be determined through a special type of gas chromatography. Though not commonly performed on a batch-to-batch basis, this testing method is used to ensure that no synthetic elements are present in any essential oils.
Using isotopic analysis testing to detect essential oil purity
Matter is made up of tiny chemical building blocks called elements. Although dozens of elements exist, each one is distinct due to the protons it contains. Sometimes, an element can exist in more than one stable form if it has more or less neutrons. When this occurs, the elements are called isotopes. The element carbon exists in two stable isotopes, carbon-12 (6 protons and 6 neutrons) and carbon-13 (6 protons and 7 neutrons). Because essential oils are organic compounds, they are composed primarily of carbon atoms and will have a certain ratio of carbon-12 to carbon-13 isotopes. This ratio varies based on location around the world. Using a special type of Mass Spectroscopy, it is possible to determine which isotopes are present in an essential oil constituent and at what amounts. If sourced from the same location, every constituent in an essential oil should have the same ratio of isotopes. If a particular constituent has an isotopic profile different than that of the other constituents, then the quality control analyst will know that a particular essential oil contains an adulteration.
Using heavy metal testing to detect essential oil purity Heavy metal testing shows the amount of heavy metal content in any given essential oil. When properly distilled, essential oils shouldn’t contain heavy metals. ICP-MS testing uses a high-energy medium called inductively coupled plasma (ICP) to ionize the sample. The sample is then run through a mass spectroscope, which separates the sample into its elemental parts and provides a reading about which elements are present and at what quantities.
