What is TFE and why is this oil better?
TFE (Tetrafluoroethane aka Florasol) is an extensively researched and utilized solvent, now commonly found in the flavor and fragrance industries. Its unique chemical properties allow it to easily extract the most delicate and volatile botanical compounds without degradation or residue, ensuring the true profile of the flower is preserved and concentrated in a full spectrum oil without winterization or distillation. No other oil can match the rich bouquet and potency of TFE.
How is it different from CO2 or ethanol?
CO2 is normally an inert gas that is pressurized to a supercritical state to condense into a polar solvent. It is generally considered a safer and greener choice because it can simply evaporate into the atmosphere rather than contaminate land or water. Unfortunately, CO2 processing is considerably more energy hungry than other methods of extraction and requires subsequent ethanol work-up to create a usable extract. This rough handling leads to diminished yield and degradation of active components like cannabinoids and terpenes.
Ethanol is a non-discriminate polar solvent that is most typically used to extract at very low temperatures (below 40C) to minimize co-extraction of unwanted plant lipids and waxes. It too requires work-up like CO2 and produces a similarly degraded product. Virtually all of the ethanol extract is further distilled to improve color and taste, but at the cost of a majority of the minor cannabinoids and terpenes.
Is it safe?
TFE is commonly used in aerosols like asthma inhalers and designated GRAS (Generally Regarded As Safe) by the FDA. It is non-toxic, non-flammable, and does not cause ozone depletion like some other Freons.
How can it be used?
TFE oil can be directly consumed, such as in a vaporizer, or infused into topicals and edibles. Its most striking feature for CBD vape carts is that it does not crash out and crystallize like most CO2 or distillate vape carts.
What about THC?
THC is co-extracted with CBD during the extraction process, but can be remediated in post-processing down to compliant 0.3% or all the way to zero through a gentle enzymatic method that preserves the original plant profile.
What about terpenes and flavor?
TFE is perfectly suited for terpene extraction and has seen widespread adoption in the flavor and perfume industries over the traditional steam or ethanol methods. For customers interested in the entourage effect and the (much) higher efficacy of full spectrum extracts, TFE CBD oil delivers more flavor and more effect than CO2 or ethanol.
