Certified Pure Therapeutic Grade®

doTERRA’s state-of-the-art lab uses the most advanced testing methods to verify the purity and potency of its essential oils.

After the aromatic compounds are distilled from the plant material, each batch is scrupulously tested to ensure that it meets CPTG Certified Pure Therapeutic Grade® standards.

doTERRA developed this rigorous criteria to certify that its oils contain no added fillers, synthetic ingredients, or harmful contaminants. Utilizing its own facilities, as well as trusted third-party labs, doTERRA essential oils undergo the CPTG process to ensure that customers receive the highest quality oil, every time.

The doTERRA mission hinges on discovering and developing the world’s highest quality essential oils, 
and we stay at the forefront of scientific advances by partnering with selected academic, industry, and scientific institutions.

Gas Chromatography and Mass Spectroscopy (GC/MS) have been touted as the standard for essential oil testing, and while they remain an early indicator of quality, they are not a definitive indicator of quality.

As such, doTERRA has developed a testing sequence that far exceeds the industry standard in both breadth and scope. Each step ensures that only the highest quality essential oils pass through quality control, quality assurance, and on to you and your family.

Each batch of essential oils goes through a battery of rigorous and definitive tests.

These tests include the following:

  1. Organoleptic Assessments

    1. Organoleptic Assessments

    In this phase, essential oil chemists, manufacturing engineers, and quality technicians manually assess the appearance, aroma, and color of each essential oil.

  2. Specific Gravity

    2. Specific Gravity

    The specific gravity portion of the testing process compares the volume-to-weight ratio to reference standards to verify oil quality and purity.

  3. Gas Chromatography/ Mass Spectroscopy (GC/MS)

    3. Gas Chromatography/ Mass Spectroscopy (GC/MS)

    During this stage, molecules are separated and identified to ensure that the chemistry of the oil matches the expected chemical profile.

  4. Fourier Transform Infrared Spectroscopy (FTIR)

    4. Fourier Transform Infrared Spectroscopy (FTIR)

    FTIR testing uses infrared light to analyze the material composition of an oil to determine if it meets doTERRA’s established standards.

  5. Optical Rotation

    5. Optical Rotation

    Optical rotation tests for chirality by measuring the amount of light bend produced by the orientation of the molecules to determine whether the molecular structure complies with the determined standard.

  6. Refractive Index

    6. Refractive Index

    A refractometer is used to determine the essential oil’s refractive index—a measurement of how light spreads through a specific substance—to ensure that the essential oil meets doTERRA’s established standards.

  7. Contamination Testing

    7. Contamination Testing

    Batches that meet the physical testing criteria are then run through a series of on-site contamination tests by expert microbiologists to confirm that there are no harmful contaminants. The oils are tested for potentially harmful microorganisms, heavy metals, and pesticides to certify safe use when proper usage guidelines are followed.

  8. Stability Testing

    8. Stability Testing

    doTERRA also conducts on-going stability testing to ensure that essential oils will maintain their purity and efficacy for the length of their intended use. In this series of tests, chambers that alter temperature and humidity are used to analyze how essential oils react when exposed to different atmospheric conditions for extended periods of time. This testing protocol ensures that doTERRA essential oils will continue to provide safe and effective benefits for years.
