Ethanol extraction is a single-stream process that can be conducted under warm or cold conditions. An example of a warm ethanol extraction. Evolution of Ethanol Extraction. Learn how a break through at Capna Fabrication might change the future of ethanol in cannabis extraction. In a maturing extraction industry, many companies have released new technologies promising to be the “next best thing”. What you probably.
CO2 vapor is not. Therefore, from a flash fire perspective, CO2 is safer. However, you may be surprised to learn that injuries and deaths from CO2 asphyxiation are somewhat common throughout the industries that use CO2 e.
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 Combine extracts and blend as desired. Chemistry allows us to control the rate of extraction and keeps plant fats less soluble with decreased temperatures.
You would lose some cannabinoids in the process. Just take the chlorophyll dude. It has some health benefits. You have got that right about the relevant cannabinoids. It does not need to taste bad. Terpines and flavinoids can be very flavorful. If mixed improperly they can taste like a sewer. I use ethanol to make my extracts- I feel that if you are competent enough to process the material then you should be aware that exposing the solvent to an open flame may not be to bright… Regardless of the solvent used-some folks will still manage to create chaos and destruction.
Have you ever tried using Ethanol Extraction as your choice for ethanol? I was using everclear for so long and a buddy of mine gave me a bottle of his solvent and it pulls out more oil than everclear and ended up being cheaper too.
I found their site its http: Unless you were using the proof Everclear…. Your post is nothing but an ad in disguise. Thanks to Canpa Labs for investing time and money and thus expanding the base of knowledge and advancing the art of cannabis! However, I doubt that they are doing anything truly new. Share and share alike folks!!
Trying to figure out if my dispensary uses this method since all they would tell me is ethanol. They are most likely using an extraction method based on sonication; the use of ultrasonic waves to increase reaction rate. So yes, I agree with this article. Ethanol over CO2 extraction. All day, every day. And people have been doing it for centuries before me. So, some skills in analytical methods plus real lab equipment is required to perform these methods correctly and safely.
In many cases, the reagents and how they are used can create dangerous situations. Consequently, many of the techniques require safety equipment, like a fume hood.
Just as important, the extraction process must be performed correctly to produce a safe product for human use, and the results should be confirmed independently with proper analytical testing. In addition, if any CO 2 remains in an extract after the process, it just evaporates. That is especially important for any preparations for medical uses as a producer using this method can guarantee that absolutely no residual solvent will be present in the final product.
Despite the need for some financial investment in a CO 2 extraction system, a manufacturer can consider various levels of equipment. For instance, Apeks Supercritical makes introductory through high-production extraction systems and even offers refurbished systems. This gives customers a range of prices to consider. Using butane as the extraction solvent creates what is known as butane hash oil.
To do this, the process starts with cannabis and liquid butane in a pressurized and heated system. By using evaporation under a vacuum, it is then possible to remove the butane solvent. The vacuum turns the butane from liquid to a vapor, making it easier to remove.
This kind of extract is also known as shatter, which is a clear material that typically includes THC, CBD and other chemical components, including terpenes. To really make shatter, which is a hard version of butane hash oil, terpene content must be kept low or it works like a solvent that makes the extract soft. The right starting sample can help to reduce the terpenes present in the final product, such as by starting with cured flowers.
On the other hand, the butane hash oil can be heated to remove terpenes after extraction as they are more volatile than cannabinoids like THC and CBD. Cannabis alcohol extraction Several common forms of cannabis extraction rely on a solvent, such as alcohol.
In brief, the cannabis soaks in alcohol, usually ethanol, the plant material is then removed, the liquid filtered, and the alcohol is removed with some form of evaporation. One of the biggest challenges is the inherent polarity of solvents like ethanol—meaning it has a propensity to mix with water and dissolve water-soluble molecules like chlorophyll. Removing the chlorophyll from the extract is important as it produces an undesirable, bitter flavor.
A cannabis tincture created using alcohol-based extraction. This method can be performed at atmospheric pressure, but the temperature is carefully controlled, especially during evaporation.
This process can also take time and must be done carefully to avoid danger as ethanol is highly inflammable. One of the biggest benefits of this form of extraction is that there is no risk of leaving toxic residual chemicals in the final cannabis extract and, it enables the co-extraction of all compounds of interest, chiefly cannabinoids and terpenoids.
