Some people ask us, “Is the purity of essential oils really that important?” or “What happens if I use essential oils that aren’t pure?” The answer is: yes, the purity of essential oils is very important. If an oil has been adulterated, contaminated, or modified with synthetic additives, the natural benefits of the plant are often compromised. This is why dōTERRA places such great importance on the purity of its essential oils. If you use an impure oil, it may be difficult to experience its benefits and use it safely. However, when using pure and unadulterated essential oils, it will be easier to use them safely and fully appreciate their potential.

How does dōTERRA ensure that its essential oils are pure?
From the beginning, we set ourselves the mission of offering the world pure, high-quality essential oils. However, without an authoritative model to follow, doTERRA decided to create its own standard for purity in the essential oils industry. Not all essential oil companies choose to adhere to high-quality standards; in fact, many take shortcuts to save time and money. Unfortunately, without rigorous testing, it's impossible to ensure that an essential oil is truly "pure." To ensure that every bottle of essential oil is pure and free from contaminants or synthetic additives, doTERRA created the CPTG™ process (Certified Pure Therapeutic Grade). The CPTG process involves a thorough analysis of each oil batch, along with independent testing to ensure transparency.

How to know if an essential oil is pure?
Before purchasing essential oils, it's important to do some research to understand how the company sources, produces, and tests its oils. Here are some questions to ask yourself:
Quality of the plant: Does the company use high-quality plants to produce its essential oils? Are the plants grown under the right conditions with proper agricultural practices?
Production methods: Does the company adopt safety procedures to protect the oils from contamination during production? Are the oils adulterated, or are synthetic additives added?
Testing methods: Does the company test each batch of essential oils? Are independent and impartial tests conducted? Are the test results made available to the public?
Storage and handling: Are the oils processed, packaged, and stored carefully to prevent chemical alterations from heat or light exposure? (Amber bottles are usually the best option for storing essential oils).

8 Ways to Verify the Purity of doTERRA Essential Oils
The CPTG quality analysis process involves eight main steps to ensure that every batch of doTERRA essential oils is pure, unadulterated, and safe for its intended use. Here are the tests used by doTERRA to ensure the purity of essential oils:
Organoleptic Analysis
Microbial Analysis
Gas Chromatography
Mass Spectrometry
Fourier Transform Infrared (FTIR) Spectroscopy
Chiral Analysis
Isotopic Analysis
Heavy Metals Analysis
Purity is one of the most important characteristics of an essential oil. When an essential oil is adulterated or contaminated, it loses its effectiveness and fails to fully meet your needs. Purity is, above all, the primary priority for doTERRA in the production of essential oils.
Ensuring the Purity of Essential Oils: The CPTG Process
-
dōTERRA initiates the CPTG testing process immediately after distillation, during which the chemical composition of each oil is analyzed. The dōTERRA production facility then conducts a second round of tests to ensure that the oils distilled and analyzed in the first phase are the same oils that arrived at the facility. A third analysis of the chemical composition is carried out when the oils are bottled before being shipped to consumers.
Each test conducted ensures that the essential oils are free from contaminants and that no unexpected alterations have occurred during the production process.
