How to Red The Label:Gritman's Classification Codes for Essential Oils

To enable our customers to make better informed decisions about our oils, we have developed this proprietary scheme for classifying Essential Oils, Absolutes, Concretes and other related products, based on how they are processed. This is called the Gritman Classification Code (GCC). It is not so trivial as the field is so complex.
Each oil must be taken individually and differences to preference may occur between professionals. Sometimes it is desirable to have an oil rectified, sometimes not. The Citrus when cold pressed have coumarins in them, which are phototoxic. If they are distilled, the coumarins are removed and many consider this to be a safer oil, while others would consider it tampered. What we will do is give you the information you need to select the best oil for you. You decide.

PROCESSES: Methods Used to Produce Essential Oils.
Blending: Using a combination of natural or synthetic oils to copy or create a new blend or fragrance.
BN: Blending, Natural: All components in the blend are natural.
BS: Blending, Synthetic: One or more component is synthetic.
Reconstituting: Blending a combination of natural or synthetic chemicals to mimic the composition of an essential oil as found in nature, e.g. Melissa & Yuzu.

RN: Reconstituting, Natural: All components in blend are natural (from other plants).
RS: Reconstituting, Synthetic: One or more components are synthetic.

Distilling: Extracting essential oils by distillation producing the volatile & water insoluble parts of a plant.

DD: Distilling, Dry: Extracting essential oils by heating within a vacuum.
DE: Distilling, DEstructive: Extracting essential oils by heating wood or plant within a confined enclosure.
DF: Distilling, Fermentation: Extracting essential oils by soaking in warming water and allowing a fermentation process to begin.
DS: Distilling, Steam: Extracting essential oils by steam distillation. Used for most essential oils.
DW: Distilling, Water: Extracting essential oils by boiling in water.

Fractionation: Additional processing of essential oils to remove "undesirables".
FF: Fractionation, Folding: Oil is re-distilled removing some but not all of the terpenes in the oil.
FT: Fractionation, Terpeneless: Oil is re-distilled and all terpenes are removed.
FR: Fractionation, Rectification: Part(s) of the oil is removed using re-distillation, heating or chilling.

Liquefied Solvent Extraction: Extracting essential oils using liquefied gases.
LC: Liquefied Cooling Extraction: Oils are dissolved in gas liquefied by cooling. Oils are then recovered by evaporating the liquefied gas, e.g. CO2.
LP: Liquefied Pressurized Extraction: Oils are dissolved in gas liquefied at room temperature by compression. Oils are then recovered by evaporating the liquefied gas, e.g. 1,1,1,2 - tetrafuoroethane.
