CBD extraction is a key step in the production of oils and derived products. Different methods are used to extract cannabidiol from cannabis plants. Each extraction method influences the purity, quality and composition of the final product. Understanding these methods is essential for consumers seeking quality products and for producers aiming to offer competitive products to the market.
1. Ethanol extraction:
Ethanol extraction is one of the oldest methods of obtaining CBD. It involves the use of ethyl alcohol to dissolve and extract cannabis compounds. This method is relatively simple and inexpensive, but can extract not only CBD, but also other compounds such as chlorophylls, which can give a bitter taste to the final product.
2. Supercritical CO2 extraction:
This method uses carbon dioxide (CO2) in a supercritical state (both gas and liquid) to extract CBD. Supercritical CO2 acts as an effective solvent without leaving toxic residues in the final product. It also allows precise temperature and pressure control to specifically isolate the CBD, producing a pure, high-quality product.
3. Oil extraction:
Oil extraction is a traditional method where vegetable oil (like olive or coconut oil) is used to extract cannabis compounds. This method is simple and safe, but it often produces lower concentrations of CBD than other extraction methods. The final product may be less concentrated and less pure than those obtained with other techniques.
4. Extraction with hydrocarbon solvent:
The use of hydrocarbon solvents such as butane or propane is a powerful extraction method but potentially dangerous if poorly controlled. This method extracts CBD efficiently, but requires specialized equipment to ensure the solvent is completely removed from the final product, avoiding any toxic residue.
5. Water extraction:
An emerging method simply uses water to extract CBD from cannabis plants. Although safe and environmentally friendly, this method is less used because it produces lower concentrations of CBD compared to other extraction techniques.
Simplified extraction process:
- Supercritical CO2: CO2 is heated and pressurized to reach a supercritical state where it acts as a solvent without leaving any residue. The CBD is extracted then the CO2 is evaporated, leaving a pure product.
- Ethanol: Cannabis plants are soaked in ethyl alcohol to extract the compounds. Then the alcohol is evaporated to obtain the CBD extract.
- Oil Extraction: Cannabis flowers are heated in vegetable oil to extract the compounds. The mixture is then filtered to obtain the final product.
- Hydrocarbon Solvent: Butane or propane is used to extract compounds from cannabis. The solvent is then evaporated to obtain the final product, but it requires further purification to remove residues.
- Water Extraction: Plants are soaked in water to extract the compounds, but this method produces lower concentrations of CBD.
It is essential to emphasize that all our CBD oils are obtained exclusively by the supercritical CO2 extraction method. This rigorous approach guarantees not only the purity of the final product but also its maximum concentration of cannabidiol.
The exclusive use of supercritical CO2 extraction is a guarantee of quality and safety for our consumers. This method preserves the integrity of active cannabis compounds while eliminating any toxic residue, ensuring high-quality products that are free of contaminants and rich in natural benefits.
By choosing our CBD oils extracted by supercritical CO2, you are choosing a safe and effective approach to fully benefit from the benefits of cannabidiol in superior quality products.
