WHAT IS THE BEST WAY TO USE HERBAL SELECT ESSENTIAL OILS?

Herbal Select essential oils are suitable for any applications involving essential oils (e.g. air freshening, perfume making, aromatherapy, etc.) as we use only pure and natural essential oils of the highest quality. For household use, we recommend adding 6- 8 drops of our oils to the Herbal Select PurMist diffuser or approximately 30 drops of essential oils per 30 mL of water in a spray bottle to create a room mist, to fill your room with glorious fragrance.

 

HOW DO YOU ENSURE THE QUALITY OF YOUR OILS?

Because identity and purity are key attributes of any essential oil, testing for these attributes is the best way to ensure an oil’s quality. At Herbal Select™ our identity and purity testing program consists of four individual tests.

  1. Gas Chromatography (GC) is a sophisticated analytical technique that uses specialized technology to separate an essential oil into its major components for analysis. The results of this testing is reviewed by our experienced analytical chemists and carefully compared to the specific peaks and lines of standard test results for the specific oil. Any lines or peaks (on the graphic output) that don’t correspond to the standard test results (unique genetic fingerprint) indicate adulteration.
  2. Fourier Transform Infrared Spectroscopy (FTIR) is another sophisticated analytical technique we utilize. A beam of infrared light is passed through a sample, which causes the chemical bonds to vibrate. Every compound has a different vibrational pattern (called specta) due to its distinct bonds, and this pattern serves as a standard for the material being tested. Highly trained chemists compare the spectra of the sample against standard spectra to determine that critical components are present and there are no adulterants. Although the two techniques are vastly different, when used together, GC and FTIR provide incredibly powerful assurance of identity and purity.
  3. Optical Rotation Analysis reveals optical activity of a substance and can reveal common forms of adulteration, such as the addition of synthetic compounds, or natural components of different botanical origin, which drastically changes the biological and aromatic properties of the oil.
  4. Organoleptic Comparison is used by our Quality Control department to go one step further than analytical testing alone. This is where our experienced, professional quality inspectors physically inspect our essential oils for clarity, colour and aroma.
