Respect of the plant's profile
Ethanol is a solvent made by plants for plants !
We work with a laboratory that uses cold ethanol extraction, inspired by the “RSO” method.
Ethanol is the best solvent when the goal is to render the original ratios and profile present in the plant : cannabinoids, terpenes, sesquiterpenes and flavonoids. Unlike lower cost preparations extracting only a targeted molecule, our oil contains all the richness and diversity of the plant, and makes it a high quality product.
After this first extraction and in order to limit the THC rate, we mix, for certain oils, an organically grown CBD isolate extracted using the “CO2” method.
The 3 advantages of the “RSO” method :
- Polarity : ethanol is one of the polar protic solvents. It is the only solvent that maintains the original chemical ratios contained in the plant.
- By plants for plants : alcohol extracts water-soluble and oil-soluble components, low boiling point 79°C (118°C for butane). The alcohol facilitates purging without evaporation of other components.
- Food compatibility : ethanol is alcohol, present in wine, beer and other pharmaceutical preparations.
Origine of ``RSO`` cold extraction
Born in 1949 in Canada, Rick Simpson has become a legend in the world of hemp. He is the pioneer of the method that bears his name (Rick Simpson Oil or RSO), which provides a high concentration of cannabinoids in the oil extracted from the plant.
Other extraction methods
Butane is a very well known hydrocarbon solvent and is very commonly used for extractions. It has a “non-polarity” that allows the extractor to capture the desired cannabinoids and terpenes without extracting undesirable ones such as chlorophyll and plant metabolites. The boiling point of butane also facilitates purging at the end of the extraction process, giving a relatively pure result. Butane is highly flammable and has caused numerous explosions that have resulted in serious injuries. Considering that the extract will be consumed, only slight imperfections in the process can cause the extract to retain a range of toxins that are harmful to humans.
Supercritical CO2 (carbon dioxide) is a liquid gas that extracts only non-polar chemicals from a plant; the solubility of many extracted compounds in CO2 varies with the pressure to allow selective extractions. The relatively low temperature of the process and the stability of CO2 also allows most compounds to be extracted with little damage or denaturation. Low toxicity and environmental impact are the main advantages. However, the lengthy purification process required to remove undesirable constituents (such as vegetable waxes and fats) calls into question the advantages obtained in supercritical CO2 extraction. The use of carbon dioxide leads to very limited extraction spectra of the plant.
