The CBD Extraction Process
CBD oil is made by extracting the compounds from the flowers and leaves of the hemp plant. There are various methods of extraction that can be used: however, the top two are CO2 and Ethanol Extraction. CO2 Extraction requires expensive equipment: however, it has an advantage of being able to selectively extract specific compounds and allows for purity of the cannabinoids and flavor (terpenes) in the refined CBD oil. Ethanol Extraction involves heating the material to achieve decarboxylation and then soaking the plant material in ethanol for a period of time. Then the liquid is filtered from the material and left in the open and allowed to evaporate. One of the advantages to this method is it does produce a high volume of full spectrum hemp extract.
CBD isolate is a crystalline solid or powder that contains 99% pure CBD. A traditional extraction process removes all the active compounds from the Hemp plant, followed by a refinement process that strips away all other Phyto cannabinoids, including THC, and any plant matter, leaving behind nothing but the CBD chemical compound in its purest form.
Water Soluble CBD
In order for CBD to become water soluble, it must be broken into very small particles, or nanoparticles and then delivered with a lipid delivery system. This requires combining with a self-emulsifier system which is actually a naturally self-assembling colloidal delivery system.
