This article is about CO2 vs. ethanol extraction and the scalability of the cannabis industry, where biased opinions on extraction methods are. Which extraction method is best for your cannabis company: CO2? Do you want to produce full-spectrum cannabis oil? The cannabis is then removed; the liquid is filtered and the alcohol purged from the extracted. Carbon Dioxide vs Ethanol Extraction of CBD CBD oil is the most interesting cannabinoid from a medical and pharmaceutical perspective, with studies.

Scrap the hash off the Plexiglas with your scraper and place it into one of the jars. Ethanol, low-grade alcohol, and butane are among the most common substances used in Solvent Extraction.
Although ethanol extracts the full range of cannabinoids and terpenes from the plant which makes the end product safe for consumption, it also extracts chlorophyll which may lead to some unpleasant side effects. Butane offers a stronger oil than ethanol, but it is more likely to contain solvents which could irritate the lungs.
All you have to do is add the liquid whether it is butane, alcohol or ethanol to the plant material. The extraction liquid will strip away the cannabinoids and flavor from the plant material but will probably take some of the green colorings too.
Once you believe you have enough cannabinoids in liquid form, heat the liquid to evaporate it down to the CBD base oil. It is extremely important to understand the various CBD extraction methods as they have a major impact on the quality of the end product; not to mention your health. The cost of CO2 supercritical extraction means it is not possible for Those who create their own CBD oils will tend to use dry ice or olive oil, which provide great purity, yield and are easy to do.
There are also other extraction methods that we have not mentioned in this guide. If you have experience in extracting CBD from the cannabis plant and would like to share your method, feel free to contact us through our Facebook page.
We also sell hemp biomass, clones and seeds. If you want to check us out you can see here. Since chlorophyll is water soluble, and the essence your after, is not. Use hot water to rinse and squeeze the material and repeat. Then the solvent process will yield a higher quality of product. I would think ethyl ether would be even better, however way more volatile of a solvent.
In any event, any reaction using ethyl ether should only be carried out by knowledgeable and qualified personnel. If you thought butane was flammable, step aside cupcake, ether is extremely volatile.
Also, keep in mind there is water in acetone too! Water is the most abundant solvent on earth, given time, it will break down anything. Why are you calling chlorophyll harmful? It actually enhances bioavilability and has other health benefits.
Chlorophyll is very easy to remove from any extraction as well. All you have to do is leave your extraction in the sun for an hour or two and let nature do it. Use fan leafs with lil clippings and used ISO I would do the same process but with high quality buds and high THC content leafs clippings and be a lot more delicate careful not too disturb it too much. Pls help me understand this process. Cbd comes home with so many benefits. Capable of treating multiple sclerosis, a very bad disease.
How do I achieve this? In the US we need to be under 0. Most companies will use flash chromatography to remove THC from my experience. Cbd is surely a fighter to deal with any kind of sleeping problems. It is free of side effects that are common in painkillers so I am using it for insomnia regularly. Far better than painkillers!

What Does Weed Do to You? This article is sponsored by Capna Labs. Capna Labs is an industry-leading extraction laboratory and research facility based in Southern California. Yet a third solvent, ethanol, has been gaining on butane and supercritical CO2 as a solvent of choice for producers manufacturing high-quality cannabis extracts. No solvent is perfect for cannabis extraction in every way.
Butane, the most common hydrocarbon solvent currently used in extraction, is favored for its non-polarity, which allows the extractor to capture the desired cannabinoids and terpenes from cannabis without co-extracting undesirables including chlorophyll and plant metabolites. That said, butane is highly combustible, and incompetent home butane extractors have been responsible for the manifold stories of explosions resulting in serious injuries and giving cannabis extraction as a whole a bad rap.
Furthermore, low-quality butane utilized by unscrupulous extractors can retain an array of toxins that are harmful to humans. Supercritical CO2, for its part, has been praised for its relative safety in terms of toxicity as well as environmental impact.
That said, the lengthy purification process required to remove co-extracted constituents, such as waxes and plant fats, from the extracted product can take away from the final cannabinoid and terpenoid profile of extracts yielded during supercritical CO2 extraction. Capna Labs , a California-based extraction company founded in , considered the benefits and drawbacks of several solvents, including butane and supercritical CO2, before choosing to work with ethanol as their solvent of choice.
Ethanol turned out to be just that: As a result, it is commonly used as a food preservative and additive, found in everything from the cream filling in your donut to the glass of wine you enjoy after work. Chlorophyll is one of those compounds which will easily co-extract when using ethanol as a solvent. When a concentrate retains chlorophyll, it will introduce a dark coloration and a bitter, grassy flavor — and unsurprisingly, not too many patients are excited about dabbing some black shatter or budder that tastes like a freshly mowed lawn.
Through research and experimentation over the span of several months, the team at Capna was able to conceive a method that bypassed both the chlorophyll and the lipids in botanical materials during extraction.
This proprietary function allows for the creation of pure ethanolic extracts. The patent-pending process is also capable of removing nearly percent of residual ethanol from the byproduct after extraction, without compromising the cannabinoid and terpene profile captured initially. The ethanol removed from the finished concentrate can be reused in multiple extractions, which effectively eliminates the production of chemical waste.
CEO Vitaly Mekk says he founded Capna Labs with a mission to lead by example, introducing professional lab standards and controls to the cannabis extraction industry. At present, Capna is working on a line of extractors capable of executing their proprietary process, and has already launched an in-house quality assurance department to provide full-spectrum testing for both the general public and retail patients.
In the meantime, the team plans to continue to raise the bar of extraction industry standards by expanding its repertoire of partner brands. For more information on partnerships with Capna Labs, please visit the Capna Labs website.
See the links below for some real-life examples of injuries and deaths from CO It may be that ethanol is as safe to use as CO2 in this application or perhaps safer. Ethanol will not cause asphyxiation and you can detect when it is present in the atmosphere through your sense of smell. Given the known flammability hazard of ethanol, those who use this solvent in their processes generally take care not to expose it to heat sources or open flames.
Also despite being fit for human consumption Ethanol does have a measurable toxicity and when looking at lethal dose is actually only about half the toxicity of Isopropyl alcohol an alcohol that is not suitable for ingestion. I realise this is not really an issue when using it as a solvent as toxic doses are way above what could be in even poorly purged oils, but inhalation of ethanol is dangerous, the flammability is a danger and while the toxicity is low enough to be relatively meaningless in oils it may be an issue when used for tinctures.
Ethanol is a good solvent choice and is less toxic than things like Naptha, hexane, methanol, acetone and even Isopropyl but it is not as selective as butane, is more toxic than Co2 and is hard to get pure in many parts of the world is also more expensive than others. If you got access to high tech labs then a lot of solvents become more useful and desirable, but for every day oil makers which still represents the majority of oil makers, thanks to the ongoing prohibition of cannabis it may not even be an option, let alone the best option.
Why would anyone working with a flammable solvent work in an area anywhere near an electron-based ignition spark, flame, etc,. The main reason is lack of another option. Now people are seeing safer alternatives like the Rosin technique for making oil without solvents but mot people have used the rice cooker method and usually use either Ethanol or Isopropyl alcohol as a solvent due to low toxicity of both, compared to other choices like Hexane and Naptha.
I have always used everclear as a solvent. The major deciding point is product safety. Ethanol is safe to consume in the quantities present, after solvent removal. But they are comparing the flammability or explosion risk with how safe it is to consume. Regarding extraction methodologies, two companies that I work with, Wildfire CBD and Smooth CBD, will soon be releasing a variety of CBD based product lines, some of which are extracted with hydrocarbon, and some with alcohol.
You will be able to compare for yourself. In states where we are licensed, we will, under different brands, have similar product lines, using THC, or the combination of THC, CBD, and full-spectrum cannabinoids. The questions of taste are, of course, just a matter of preference; though for reason stated, many prefer hydrocarbon extracted products.
Laws are continuing to place severe safety restrictions on these processes, and it is debatable as to where and for how long these will be permitted.
Intuitively, as well as from anecdotal experience, the full-spectrum provided by food-grade ethanol, extracted slowly, under cold temperatures, seems to be superior in terms of medicinal benefit.
However, this is a very broad and sweeping statement; and, it is not something, as was suggested, that can properly be elucidated in the lab setting. Rather, to have definitive proof, we will need standardized random, double-blind, clinical trials, such as those done in the pharmaceutical industry.
While we do intend to proceed in this direction, as permitted by law, it is an expensive, and exhaustive process, and will take time. The downside here is that the price paid for a purer compound is the loss of many of the minor cannabinoids, as well as terpenes, which are believed to play a vital role in creating the maximum benefit. Thus, we and others, are experimenting with procedures such as starting with a pure cannabinoid oil, and then adding back minor cannabinoids and terpenes, derived either from cannabis, hemp, or other plant material.
It remains to be seen whether this can adequately duplicate the full spectrum offered by the whole plant, without the extra lipids, dyes, and so forth. Ultimately, as scientists, we try not to be biased in our expectations, and we tend to look for conclusive evidence; though anecdotal information is crucial, as a guide, both in research, product development, and healing arts in general.
Beyond this, I can only add that our goals very much revolve around quality, consistency, efficacy, cost savings, availability, customer service, and education. I look forward to presenting more for consideration in the near future. Thanks for the reply. We do a full spectrum on potable The higher the potency of alcohol the better the extraction.
Utilising spagyrics ensures for an extraction in the original ratios. Esterisation needs to occur as well. We produce an extract full spectrum delivering It has an amazing medicinal ability. Unfortunately, sponsored articles tend to have an inbuilt bias.
From a medicinal standpoint, the extraction of all relevant cannabinoids is the single most important issue. I hope a neutral, professional source such as a reputable university or long established lab with impeccable credentials, will carry out the necessary analysis so we can finally get to the bottom of this very important issue. Yes I am also a chemist, ethanol is a great solvent for extracting the full spectrum of thc, canabanoids, and terpenes.
This is where chemical principles steps in, my 1st extraction is
