In today’s health-conscious world, where natural solutions are increasingly valued, the conversation around essential oil purity is more important than ever. With so many options available, how can you feel confident you’re choosing an essential oil that is carefully sourced and quality tested? This is where doTERRA’s Certified Pure Tested Grade® (CPTG®) quality protocol comes into focus, representing the company’s approach to quality assurance and testing.
Learn more about doTERRA’s CPTG process and what helps these essential oils stand out in terms of quality control and transparency.
What is CPTG? More Than Just “Pure”
The word “pure” can be used broadly within the essential oil industry. doTERRA’s CPTG quality protocol reflects the company’s commitment to extensive testing and quality practices. Rather than being a regulatory certification, CPTG describes a series of internal testing standards designed to help verify that oils are carefully sourced and evaluated for quality.
This multi-step testing approach is intended to help ensure products are evaluated for contaminants, adulteration, and consistency.
The Journey of Quality: From Source to Bottle
doTERRA’s quality focus begins well before the oil reaches your diffuser or personal use. Their process typically includes:
Sustainable Sourcing:
doTERRA works with growers and distillers around the world, often in regions where each plant naturally thrives. Through their Co-Impact Sourcing® initiative, the company aims to support responsible sourcing practices while maintaining oversight of the supply chain.
Careful Cultivation and Harvesting:
Plants are harvested according to timing and conditions that support optimal oil composition. The quality of the botanical material plays an important role in the final essential oil profile.
Rigorous Testing:
Quality testing is a central part of the CPTG process. Batches of doTERRA essential oils undergo multiple tests, which may include:
Organoleptic Testing: Evaluates aroma, appearance, and consistency.
GC/MS (Gas Chromatography/Mass Spectrometry): Analyzes the chemical profile of the oil to help verify composition.
FTIR (Fourier Transform Infrared Spectroscopy): Used to help confirm consistency between batches.
Microbial Testing: Screens for microbial contamination.
Heavy Metal Testing: Evaluates for the presence of heavy metals.
Pesticide Testing: Screens for certain agricultural residues.
Chirality Testing: Helps assess the natural composition of aromatic compounds.
Isotopic Analysis: Used to help differentiate natural from synthetic components.
Why CPTG Matters
For individuals seeking thoughtfully sourced essential oils, understanding CPTG can provide helpful context:
Quality Awareness:
It reflects doTERRA’s internal commitment to testing and quality control practices.
Consistency:
Detailed testing helps support batch-to-batch consistency in aroma and composition.
Transparency:
doTERRA provides batch-specific reports through the Source to You® platform, allowing customers to review testing information for their particular bottle.
Choosing doTERRA essential oils means choosing products supported by the company’s detailed quality testing process. For many users, this provides added confidence in the sourcing, evaluation, and consistency of the oils they bring into their homes.
