The Miracle Quality Promise

At Miracle Essential Oils™, we strive to create the highest quality products. We’re committed to ensuring that each of our essential oils thoroughly meets industry standards and exceeds customer expectations. In an effort to make our practices more transparent, we’d like to share with you the process of how we source and test our oils.


Each essential oil undergoes exhaustive and rigorous scientific testing to guarantee the utmost quality. We utilize a Gas Chromatography Mass Spectrometry (GC-MS) process, an industry standard technique that breaks down and analyzes the individual molecules in each oil to ensure that they are within desired quality specifications.

Our comprehensive quality process tests for everything from odor to appearance, refractive index (the speed at which light, when passing through an essential oil, is refracted), specific gravity (the weight of an essential oil) and optical rotation (the direction to which light bends when it passes through an essential oil) - all of which are indicators of an essential oil’s purity and authenticity.

Each oil comes with a specifications sheet that provides an acceptable range that testing results should fall within, along with a Certificate of Analysis and Authenticity (COA) that lists the test results in detail. Other details provided in the certificate include the essential oil’s country of origin, botanical name (if applicable), and whether it is non-GMO (Genetically Modified Organism) or natural (if applicable).

When further analysis is needed to verify an oil’s purity and naturalness, it is subjected to another battery of tests, including Carbon Dating or C14 testing, which determines whether an oil contains synthetic components.

Our Quality Control
& Testing Process

We're committed to providing only the highest-quality essential oils to our customers. As our Quality Promise to you, we ensure that before any oil reaches your doorstep it must has passed the following stringent scientific testing qualifications.

  • Gas Chromatography (GC) Analysis

    This is the process of breaking the oil sample down to its most basic compounds by dissolving in a solvent and vaporizing into a gas. This allows for a detailed analysis of the individual compounds to determine what molecules are present and at what quantity.

  • Flame Detection Ionization (FID) Analysis

    Once the sample is in a gaseous state we're able to apply heat to gain a unique profile of the components within the oil sample. This process provides a 'footprint' of the oil for analysis against known compounds. Finally, we're given a specific percentage of each compound present within the oil sample. This process is the primary test for quality in our essential oils.

  • Mass Spectrometry (MC) Testing

    This scientific technique measures the amount and type of individual molecules by analyzing their mass-to-charge ratio. Through measuring the different elements at the ionic level, we're able to further determine the exact chemical composition of each oil sample. This ensures that each oil is completely free of any synthetic or inauthentic ingredients.

  • Refractive Index (RI) Testing

    Refractive index measures the speed at which light passing through an essential oil is refracted. Every oil is made up of a unique combination of constituents. These constituents predictably influence the speed and number of degrees at which they refract light. If an oil is inauthentic, the speed and degree of refraction may be thrown off.

  • Specific Gravity

    Specific gravity measures the weight of an essential oil at 25 degrees Celsius. Every oil is made up of a unique combination of constituents. At a given temperature, these constituents have a predictable weight. If an oil is inauthentic, the weight may be thrown off.

  • Optical Rotation

    Optical rotation measures the direction and the degree to which light rays bend or rotate as they pass through an essential oil. Every oil is made up of a unique combination of constituents, which predictably influence the direction and degree to which light rays bend as they pass through the oil. If an oil is inauthentic, the degree of rotation may be thrown off.
