Why Certified Pure Therapeutic Grade Essential Oils?
Purity is one of the most important characteristics of essential oils. Among the things that can affect purity are poor production processes and the development of synthetic essential oil variations. If you want to get the best results possible, you’d want to opt for Certified Pure Therapeutic Grade (CPTG) essential oils. These oils, such as dōTERRA undergo rigorous testing to ensure purity and quality.
CPTG quality testing is done to ensure that essential oils are made by using proper methods of growing, harvesting, and distilling their plant source. It is done through a series of processes that include:
- Validation of Quality
Under this process, each essential oil is reviewed for chemical composition after plant selection, harvesting, and distillation. Then, it is tested two more times to confirm that it has remained free of contaminants and unexpected alterations during production.
- Organoleptic Testing
Organoleptic testing involves the use of the human senses to determine the quality and acceptability of the product.
- Microbial Testing
Under microbial testing, a batch of essential oils is analysed and tested for the presence of micro-organisms like fungi, bacteria, viruses, and mould that can be detrimental to your health. Samples are taken before and after the essential oils are packed to ensure they haven’t been contaminated during the packaging process.
- Gas Chromatography and Mass Spectrometry Analysis (GC/MS)
In this process, essential oils are vapourised and passed through a long column to separate them into individual components. This is to determine the exact chemical composition of a particular essential oil.
- Fourier Transform Infrared Spectroscopy
Fourier Transform Infrared Spectroscopy (FTIR) is designed to ensure that each batch of essential oil is potent and consistent. As part of this test, structural components of essential oil compounds are analysed by passing them through infrared light.
- Heavy-Metal Testing
Heavy metal testing determines the heavy metal content in the essential oil. Ideally, pure essential oils do not contain heavy metals when distilled
