Many people are unaware of the various cannabis extraction methods that are used to extract cannabinoids THC, CBD etc and their essential oils terpenes. Some of those methods include:. Today we are going to focus on Ethanol and CO2 cannabis extraction because they are the most commonly used techniques when it comes to making extracts and tinctures. Oils and butters are great for the home crafter, but it can be difficult to determine exactly how much extracted CBD or CBG is in the final product.
This is my preferred method of extracting cannabinoids and is the technique that FlowerChild uses; it takes longer and is more expensive in the long run, but I believe this is what makes our products work as well as they do. The hemp flowers are put into large containers and proof food grade alcohol is poured over them and agitated for a while to extract the cannabinoids.
This mixture is heated to around degrees and the alcohol is slowly cooked off, leaving a rich, dark, molasses-like oil.
This oil extract is filled with the goodness and healing potential of whole plant medicine. As a supplement and possible treatment for cancer, whole-plant cannabis oil can be orally administered in minute quantities or applied directly to the skin. Sublingual delivery under the tongue is the preferred method of ingestion and is the best way to get maximum benefits. Not only is it a convenient way to medicate, but intake through the oral mucosal membranes in your mouth provides for rapid and effective absorption; it goes directly into your systemic circulation because of the increased bioavailability of the cannabinoids.
FlowerChild takes this whole-plant cannabis extract and infuses it into cold-pressed grape seed oil to create our hemp CBD and CBG products. Our topical salve products have added essential oils and herbs, but our tinctures are pure grape seed oil and cannabis extract, with a peppermint oil option for taste. Carbon dioxide CO2 is a supercritical fluid, meaning it converts into a liquid form when pressurized.
At the same time, it is a pure chemical substance that occurs naturally and leaves behind no residues. Accordingly, the Supercritical CO2 extraction method aka CO2 extraction can help ensure cannabis concentrates are pure.
Supercritical CO2 extraction is a standard extraction method for the food and herbal supplement industries. CO2 is used to produce carbonated soft drinks and as an extraction solvent when producing essential oils. It is also used to remove caffeine from coffee beans in order to make decaffeinated coffee, and as a solvent for dry cleaning.
The CO2 extraction process allows compounds to be extracted with little damage and low toxicity. It utilizes a high pressure vessel containing cannabis that essentially pulls the phytocannabinoids out of the plant. Supercritical CO2 is inserted into the vessel and pumped through a filter, where it is separated from the plant matter once the pressure is released.
For Whole Plant Therapy it is vital that you get the terpenes as well as the cannabinoids. Lavender would not be lavender if the terpene linalool was removed. Think about it. The most important difference here is that the alcohol cannabis extraction retains the chlorophyll, all the naturally-occuring terpenes and cannabinoids, and all the other plant compounds that contribute to healing. Chlorophyll is very important in that it oxygenates the body and creates an alkaline environment, and cancer and other diseases cannot survive in an alkaline environment.
Terpenes are the essence of the plant and one of the main healing factors.Strawberry DNA Extraction - STEM Education Activity
All the flavonoids and other plant compounds also contribute healing potential and do best when they are working together in their natural form, the way nature intended. Alcohol extraction is a very gentle way of extraction that has been the go-to for herbalists for centuries.
Ethanol extractions are more natural, more gentle, and more effective. Give your body the best chance for healing!Ethanol, or Ethyl Alcohol, is a clear, colorless, flammable liquid with high volatility. Produced from the dawn of mankind, alcohol is ingrained in human history.
Available in many concentrations, grades, and purities, it has applications in food, medicine, and manufacturing. Due to its unique solvation properties, ethanol is used by oil extraction specialists, as a denaturant for tissue cultures, and even in universities to conduct lab experiments.
Since alcohol is also considered a drug, it is regulated by federal and state agencies. Choosing the right type of ethanol, denatured or undenatured, is critical for cost, quality and safety.
History of Denatured Ethanol. Bymethanol, or wood spirits, was added to ethanol so it could be used for industrial purposes at lower tax rates .
During Prohibition, even more toxic chemicals were added to alcohol to discourage drinking. Today, denaturized alcohol, or methylated spirits, might contain methanol, isopropyl alcohol, acetone, ketones, or other poisons. Undrinkable, it is exempt from federal alcohol excise tax.
The TTB, the Alcohol and Tobacco Tax and Trade Bureau, regulates the taxation, formulations, permitting and uses of both ethanol and undenatured ethanol. Ethanol intended for foods and fuels is typically produced by fermenting grains and distilling off the ethyl alcohol.
When ethanol reaches Although ethanol boils at To concentrate ethanol to Ethanol enters the cell was through the lipid bilayer membranes in nanoseconds, interacting with the hydrophobic portions of the protein and quickly replacing water in the cell . The isopropyl present in reagent grade ethanol might even aid paraffin infiltration. Non-Denatured Ethanol. If subject to excise tax, it is more expensive, but a permit may not be required. You must be 21 to purchase it.
Check state laws and consult with your EHS coordinator before ordering. Tax-free Alcohol is pure non-denatured Hospitals, charity clinics, government labs and universities can qualify for tax-free usage with permit approval.
Lab students might use non-denatured ethanol to learn how to run GC or to conduct synthetic organic reactions. Hospitals pharmacies can compound prescriptions or run analyses with pure ethanol. Since it is hydroscopic, it should remain tightly capped.
Non-Beverage Drawback. When using food-grade non-denatured ethanol to manufacture a non-beverage food, flavor, or perfume, you may be able to claim a return on TBB alcohol excise tax. Industrial Non-Beverage Ethanol. Pure non-denatured ethanol does not contain adulterants and is a popular tool for manufacturing culinary extracts, essential oils, tinctures, and even tobacco flavors. If pure ethanol is a raw material for foods or beverages, federal excise tax might apply. Because ethanol is a polar solvent, it will extract both water and oil soluble components, like chlorophyll and terpenes.
In cold-process extraction, it might prevent heat-induced degradation. Whether used as a processing agent for winterization or as a wash for other extraction processes like CO2, ethanol is a popular choice for extraction specialists. Since it is pure, it leaves little to no residual.
Ethanol is a flammable, mildly toxic liquid that can be ignited at most ambient temperatures.Both ethanol and isopropanol are organic compounds known as alcohols. The key difference between ethanol and isopropanol is that ethanol has a linear molecular structure whereas isopropanol has a branched molecular structure. Both ethanol and isopropanol contain —OH hydroxyl groups as their functional group. Ethanol is also called ethyl alcohol. Another name for isopropanol is 2-propanol.
Overview and Key Difference 2. What is Ethanol 3. What is Isopropanol 4. Ethanol is an alcohol having the chemical formula C 2 H 5 OH. Ethanol has many uses including the application as a fuel, as an ingredient in food and beverages industry, etc. Ethanol is a flammable, volatile liquid with a characteristic odour and a sweet taste.
Ethanol contains an ethyl group bonded to a hydroxyl group. Due to the presence of —OH groups, ethanol molecules can form hydrogen bonds with other hydrogen bond forming molecules.
Due to the difference between the electronegativity values of the oxygen atom and carbon atom, the ethanol molecule is a polar molecule. Therefore, ethanol is a proper solvent for polar compounds.
Ethanol is the main ingredient in the production of some alcoholic beverages. And also, it is used as a solvent for paints.
Above all, ethanol is a fuel. And also, it is a useful intermediate in the synthesis of different chemical compounds such as ethanoic acid, polymers, esters, etc. Isopropanol is an alcohol having the chemical formula C 3 H 8 O.For years, flower was king.

While this might remain true in some markets, flower profits are becoming leaner. There has been a significant decrease in flower price in the most mature markets due to the expansion of outdoor growing techniques that produce high-quality flower in large quantities, as well as market saturation driving prices down.
The second assumption is that two potential outcomes of yield exist from the extraction and refinement process i. More revenue can be gained through scale and the manufacturing of extracted products than through flower sales. The Food and Drug Administration FDA classifies ethanol as a Class 3 solvent with low risk for acute or chronic toxicity in pharmaceutical manufacturing processes where the residual is less than 5, ppm or 0.
The FDA also implies that residual solvents in this category should be limited to 0. As such, OSHA requires that ethanol vapors be held at 25 percent of the 3. Therefore, areas containing ethanol in production facilities must maintain no more than a 0.
Numerous other considerations apply to the storage and use of ethanol in manufacturing laboratories that could fill a column of their own, so I will simply outline that, when it comes to storage, the maximum flammable cabinet storage is 60 gallons, and the maximum storage permissible outside of a flammable cabinet or storage room is 25 gallons.
Ethanol extraction is a single-stream process that can be conducted under warm or cold conditions. An example of a warm ethanol extraction processes is the Soxhlet technique. This technique essentially boils ethanol in a flask or pot, then condenses the alcohol on a cooled-coil, which then drips through the packed flower material, stripping the cannabinoids and terpenes during the process. The advantage to this approach is that the extraction is time efficient and of relatively low solvent-to-feed ratio.
Decarboxylation is the conversion of THCA, for example, to THC through heating and agitation that yields carbon dioxide during the process. Therefore, heated ethanol extractions might require additional dewaxing and clarification steps. This type of technique is also limited in the number of products it can produce because all the acid-form cannabinoids are decarboxylated during the extraction. Therefore, it can be used as an extraction solvent at room temperature or under supercooled conditions.
Using ethanol at room temperature or under cooled conditions are the most common practices because these conditions allow for the retention of cannabinoid acid forms that can be leveraged to manufacture shatters, THCA crystals or THCA-rich oral formulations. A few differences exist between the outcomes of room temperature and supercooled ethanol extractions. First, room-temperature extractions generally extract more waxes and pigments than supercooled techniques, which results in additional dewaxing and clarification steps.
However, room-temperature extraction techniques are more efficient.
In short, ethanol is a very good solvent as it applies to the extraction of cannabinoids and terpenes. In the literature that describes the solubility of cannabinoids in ethanol, there is no definitive carry capacity, but many sources suggest that cannabinoids are soluble in ethanol at a ratio meaning that 1g of THC is soluble in 1mL of ethanol.
Finally, ethanol extraction can be conducted as expensively or inexpensively as the manufacturer desires. Ultimately, there is always one major problem to address with ethanol extraction beyond the safety requirements: downstream solvent handling. All types of ethanol extraction require that between 0. The reason for this requirement is not due to the solubility of the cannabinoids or terpenes; it is due to the absorbent nature of the plant material.
To extract the solutes from the feed material, ethanol must fully saturate the flower or trim. For that reason, a significant volume of ethanol is needed to execute the process with an efficiency rate of more than 90 percent. While some automated machines have built-in processes to minimize the required ethanol volume, the best-case scenario is that the amount of ethanol required ranges from 0.
Machines with automation features have also compensated for the problem of squeezing the ethanol from the plant material by adding spin-of-compression cycles to their processes. This is helpful because recovering all the ethanol from saturated plant material—which holds cannabinoids and terpenes—can be a difficult and messy affair with basic approaches.
So, how does one deal with the large amount of ethanol required to extract the cannabinoids from a highly productive cannabis grow? The answer: planning and large solvent-recovery systems. To meet that requirement, the ethanol extraction system will need to process 4.

Difference Between Isopropyl and Ethanol
Filtered through a coffee filter into a pyrex and put a fan over it to let it evaporate until morning. What's left has been absolutely awesome. My question Seems to work pretty well.
If you're smoking it then no you dont need to decarb it. How it feels? I think this has been disproven…? Tastes absolutely amazing. Just got done sharing some with close buddies and they loved it. Really does the job too. Suuuuuuuper potent. Can't wait to try it again with another strain to see if holds true. Probably the easiest way to make extract. Perfect for beginners. Just don't spill the pan that you fill up with THC laden isopropyl. Did that the first time I ever tried this method.
I suggest having your evaporation container in it's final resting place before filtering into it. It is a matter of preference in my opinion. Personally I like it when it has been de-carbed. Either method will get your super stoned though. Cool to see some other people rocking the alcohol extractions - I far prefer it to most butane based extracts.
I have a fat bottle of proof everclear - thank you arizona! With it shouldn't take much, maybe a minute, two at most. If you leave it in too long it tends to pick up a lot of the chlorophyll and will start to taste sort of nasty.
You will have to play around with it a bit to see what works best for you.Miscible with water, ethanol, ether, and chloroform.

Registered Capital:. Plant Area:. Sample Available.Isopropyl alcohol — also known as isopropanol — is commonly known as rubbing alcohol. Typically, isopropyl alcohol sold for consumer use is blended with water and is sold as an antiseptic or cleaning solution.
The chemical formula for isopropyl alcohol is C 3 H 8 O. Isopropanol, which is another name for isopropyl alcohol, can be used as an antiseptic, a solvent or a cleaning agent. It is important to exercise caution when using isopropyl alcohol, since it is flammable and can cause adverse effects on your health if used improperly or ingested. Isopropanol and isopropyl alcohol are different names for the same chemical compound. The confusion comes from mixing two standards for naming chemicals.
The correct name under the IUPAC system is Propanol; however, isopropyl alcohol is the most commonly-used name for this chemical. Isopropyl alcohol is a clear flammable liquid at room temperature, and is capable of being mixed with water.
Isopropyl alcohol has an odor which is similar to that of ethyl alcohol commonly known as drinking alcohol. In addition to being used as a cleaning solution or antiseptic, isopropyl alcohol is commonly used as a solvent. Alcohols such as isopropanol mix together well with other chemicals that have similar chemical structures, such as some types of ink and paint. This property of isopropyl alcohol allows it to be used to dissolve many organic compounds that other solvents, such as water, cannot dissolve.
Isopropyl alcohol may also be used for dissolving some types of plastics, such as acrylic and epoxy resins. It is important to use caution when working with isopropyl alcohol, since it is flammable and can have some negative health effects.
For example, inhaling isopropyl alcohol vapors may irritate your respiratory tract, and high concentrations of isopropyl alcohol vapor can cause dizziness, drowsiness, headache, staggering and unconsciousness. Ingestion of isopropyl alcohol can cause gastrointestinal issues such as cramps, vomiting and nausea. Isopropyl alcohol can also irritate your skin and eyes, as well as cause eye damage.
To avoid accidental overexposure to isopropyl alcohol, you may wish to take precautions such as wearing protective equipment — such as lab goggles and protective gloves — as well as working with isopropyl alcohol in a well-ventilated area.
