To avoid the risk of toxic residue, solvent extraction can use natural solvents instead, such as olive oil or ethanol. These solvents are just as effective at extracting CBD oil, but remove the risk of toxic residue.
During CO2 extraction, a series of pressurized chambers and pumps are used to expose CO2 to high pressure and very low temperatures, resulting in an extracted oil containing high amounts of CBD.
Many people know that CBD comes from cannabis. It’s right there in the name: cannabidiol.
The precise nature of CO2 extraction also makes it suitable for producing specific concentrations of CBD oil. Manufacturers can simply adjust the solvent and pressure ratios to achieve the desired concentration of CBD.
Full-spectrum CBD oils also contain other beneficial elements from the plant material, such as terpenes and amino acids. Many people prefer full-spectrum CBD oil because of the “entourage effect.” While this effect has not been proven, some users believe that the CBD is able to engage the endocannabinoid system more effectively when more cannabinoids are present.
CBD products made using other extraction methods can be safe and high-quality as well, but there can be more risk with these products. Specifically, CBD products that were made using hydrocarbon extraction may contain solvent residuals. And while steam distillation and natural solvent extraction are lower-risk, they can produce lower or inconsistent amounts of CBD, which can affect the cost/mg value of your CBD product.
There are pros and cons to each extraction method. At CBDOil.org, we recommend CO2 extraction. While it is the most expensive extraction method, it consistently produces the highest concentration of CBD, resulting in a quality product. It’s also one of the safest extraction methods, leaving behind no neurotoxic residue.
Importantly, the cannabinoids extracted using this method are the purest and contain no chemicals or contaminants. If you source your supplies from a reputable company that uses this extraction method, it will ensure that the products you manufacture using them will be of the highest possible quality.
As a CBD manufacturer, you are striving to ensure that the cannabidiol products you manufacture are of the highest quality.
Ethanol extraction operates under zero vapour pressure and is significantly less-flammable than CO2 — making for a safer extraction environment.
What is the best CBD extraction process for manufacturers?
As manufacturers, it’s crucial to understand the various CBD extraction processes and, more importantly, how they can influence the end product and its health benefits.
You need a favourable CBD/THC ratio. The extra-high CBD content renders the psychoactive effects of THC inert even in plants that have a THC concentration of up to 6%. This was proven in research carried out by Western University and published in the Journal of Neuroscience.
This high cost helps to explain why top-quality CBD oil costs more than you may expect. Another reason for the high cost is that UK CBD laws make it difficult for extraction to be done in the UK; therefore, many of the oils are extracted abroad and then imported into the UK.
With the ever-growing popularity of CBD oils, consumers are more educated about products and their range of health benefits.
