First things first, what exactly is ethanol? Ethanol, also known as ethyl alcohol or grain alcohol, is a clear, flammable liquid that is made from plants. You've likely encountered it before in various forms, whether in alcoholic beverages or household products. But what sets ethanol apart is its versatility. Derived from renewable sources like corn, wheat, or sugar cane, apples and more, ethanol is not only eco-friendly but also widely used in industries ranging from pharmaceuticals to cosmetics.

In the world of cannabis processing, ethanol extraction stands out as a key method for extracting valuable compounds from the plant. Whether you're new to the concept or seeking to understand the latest advancements, this guide will walk you through the basics of ethanol extraction, its evolution within the cannabis industry, and what the future holds for this fascinating process.

What is the ethanol extraction method?

Let's start with the basics: what exactly is ethanol extraction? Simply put, it's a method of using ethanol to pull out desired compounds from the cannabis plant. Ethanol has been utilized for centuries in various industries, including perfumery, food production, and medicine, thanks to its ability to dissolve a wide range of substances.

Ethanol extraction has come a long way over the years, evolving alongside advancements in technology and our understanding of the process. What began as a simple method has transformed into a sophisticated technique capable of producing high-purity extracts.

In the early days, techniques involved soaking the plant material in ethanol and then separating / straining plant material from the alcohol cannabinoid solution. From there, the alcohol simply evaporates leaving the cannabis resin. While effective to some extent, these methods lacked precision and often resulted in impure extracts. Additionally, the alcohol evaporation methods resulted in the total loss of the alcohol with no ability to recover and reuse.

Ethanol Evaporation & Recovery

Ethanol recovery typically occurs during the evaporation stage of the extraction process. After the plant material has been soaked in ethanol to extract desired compounds, the ethanol-extract solution needs to undergo evaporation to remove the solvent and concentrate the extract.

Steps of Evaporation:

  1. Heating: The ethanol-extract solution is heated to a specific temperature, typically below the boiling point of ethanol. This heat helps accelerate the evaporation process.

  2. Evaporation: As the solution heats up, ethanol evaporates, turning from liquid into vapor. This vapor contains ethanol along with other volatile compounds extracted from the plant material.

  3. Condensation: The ethanol vapor is then condensed back into liquid form using a condenser. This condensed ethanol is collected and can be reused in subsequent extraction cycles.

  4. Separation: The remaining extract, now free from ethanol, undergoes further processing to remove any remaining impurities and concentrate the desired compounds.

The Importance of Ethanol Recovery

Recovering ethanol after extraction is essential for several reasons:

  1. Cost Efficiency: Ethanol for extraction can be expensive, especially when working on a large scale. Recovering and reusing ethanol can significantly reduce extraction costs.

  2. Environmental Impact: Ethanol extraction is considered eco-friendly, but minimizing waste by recovering ethanol helps further reduce environmental impact.

  3. Product Purity: Recovering ethanol ensures that the final extract is free from solvent residues, meeting quality and safety standards.

Modern Techniques: Cold Ethanol for Extraction

Today, one of the most exciting developments in ethanol extraction is the use of cold extraction methods. By chilling the ethanol to extremely low temperatures, we can increase its selectivity, meaning it's better at pulling out specific compounds while leaving unwanted substances behind.

Cold ethanol extraction involves loading the plant material into an extraction chamber and introducing chilled ethanol to soak the material. The resulting solution is then processed to remove the solvent, leaving behind a highly concentrated extract ready for further refinement.

The Future of Ethanol for Extraction

As the cannabis industry continues to grow, so too does the need for efficient extraction methods. Technologies like continuous-feed centrifuges and membrane filtration are revolutionizing the way we extract and refine cannabis and hemp extracts.

Automation is also playing a significant role in streamlining the extraction process, reducing costs, and increasing throughput. With advancements in technology and a deeper understanding of the extraction process, ethanol extraction is poised to remain a cornerstone of cannabis processing for years to come.

Ethanol extraction is a versatile and effective method for extracting valuable compounds from the cannabis plant. From its humble beginnings to the cutting-edge techniques of today, ethanol extraction has undergone a remarkable evolution, paving the way for a more efficient and scalable cannabis industry.

As we look to the future, it's clear that ethanol extraction will continue to play a vital role in meeting the growing demand for cannabis extracts. With ongoing advancements in technology and a commitment to innovation, the possibilities for ethanol extraction are truly endless.

Conclusion

In conclusion, ethanol for extraction is a versatile solvent that has revolutionized the cannabis industry. Whether you're a manufacturer looking for high-purity extracts or a consumer seeking premium products, ethanol extraction offers a safe, efficient, and cost-effective solution. With ongoing advancements in technology and a deeper understanding of the process, the future of ethanol extraction in cannabis processing looks brighter than ever.

Ethanol for Extraction: 200 Proof, 190 Proof, or Ever Clear? – 190 Proof vs 200 Proof for Extraction

200 proof ethanol extraction oil

Ethanol for Extraction: 200 Proof, 190 Proof, or Ever Clear?

Ethanol production contributed $34.7 billion to the country’s GDP. Manufacturers use that solvent to make sanitizers, extract oils, and as a cleaning agent.

Alcohol grading depends on the solvent’s concentration and the impurities present. In this article, you’ll learn what makes 200 proof ethanol vital in extraction procedures. And factors making it better than 190 proof ethanol or Everclear.

What is 200 Proof Ethanol for Extraction?

Vendors call the product 100% absolute, anhydrous, or dehydrated alcohol. However, it’s challenging to gain a 100% solvent concentration because it evaporates fast. Therefore, you’ll only get 99%+ ethanol processed from advanced molecular filtration techniques. And that means that the final product will contain little to no water.

The solvent doesn’t have toxic additives such as kerosene, isopropyl alcohol, or acetone that render it bitter and foul-smelling. 200 proof ethanol is often used in foods and beverages. For example, you’ll find the liquid in whiskey, rum, and vodka beverages. Or as the leading solvent that botanical oil manufacturers use in the extraction process.

High-Performance Liquid Chromatography (HPLC) is a technique that pure ethanol creators use to ensure purity. Some contaminants tested using that method are heavy metals such as lead, arsenic, and thallium. And after analysis, the pure ethanol has a concentration of 99.98%, with the rest being trace amounts of water.

How Does 200 Proof Ethanol Affect Extraction?

When you use USP grade 200 proof pure alcohol, you’ll have a high-quality end product. How? By preventing the solubilization of unfavorable impurities such as chlorophyll, pyrogens, and microbes. Also, the little water in absolute ethanol catalyzes the oxidation of pathogenic cell membranes and prevents combustion hazards.

The product helps you prevent disease transmission to your customers. When ethanol eliminates microbes such as mites, microbes, and fungus, you’ll get that benefit. Furthermore, alcohol increases your company’s yield and enhances quality consistency.

200 Proof Ethanol for Winterization

Winterization is a technique used to refine oil in the botanical oil industry. First, the oil extract is dissolved in ethanol, and then the mixture is cooled in a freezer. The cold temperature allows for separating different compounds based on their melting and precipitation points. This process causes the fats and waxes with higher melting points to solidify, which can be removed through filtration, centrifugation, decantation, or other separation processes. After removing these solids, a pure, liquid oil extract can be further processed and used.

The botanical extraction industry prefers using alcohol in the winterization extraction technique because the solvent solubilizes alkaloids, terpenes, cannabinoids and other beneficial oils that enrich the customer’s experience.

Apart from ethanol for extraction, essential oil manufacturers also benefit from ethanol as the ideal solvent. They remove waxes and lipid impurities with ethanol.

Ethanol is a pioneering solvent that could lead to the innovation of new medications and treatment modalities. Recent research supports that statement by confirming that pure alcohol preserves the integrity of tissues and nucleic acids of many plants. Thus serving as the basis for recycling the plant biomass waste acquired after extraction.

200 Proof Ethanol for Terpene Extraction

Ethanol facilitates extract of over 100 terpenoid molecules, together with significant cannabinoids. Distillers thus prevent the evaporation of those compounds, which could happen with steam distillation or vaporization. Therefore, extracting a highly potent product with ethanol for extraction.

What is 190 Proof and Everclear Ethanol?

Everclear Ethanol

Everclear is an alcohol brand that an entrepreneur named Luxco created in 1950. That company sells colorless and odorless 190 proof / 95% ethanol.

Manufacturers make the solvent from selected grains, hence the name grain alcohol. And distilleries alter, dilute, package, and distribute Everclear to ‌food-based industries.

190 Proof Ethanol

The solvent contains 95% food-grade alcohol, similar to Everclear. That classification means that water accumulates a 5% range in any product volume sold. Moreover, the ethanol doesn’t have any denaturants. Thus, it’s safe for human consumption.

What are the Differences Between 200 Proof Ethanol and 190 Proof or Everclear?

Alcohol Per Unit Volume

There’s a significant difference in the water content found in 95% and 100% ethanol. You’ll get more of that solvent when you purchase absolute alcohol instead of Everclear. Consequently, you’ll produce high-quality and high-yield botanical extractions and tinctures.

Product Availability

Some states in the U.S, such as California, Ohio, and Maine, ban the sale of Everclear. In contrast, you’ll often purchase 200 proof ethanol without a permit. And some reputable companies, such as Simple Solvents, will deliver the product to your home or business address. However, ensure that you comply with your state’s laws and regulations.

Product Quality

Simple Solvents’ 200 Proof and 190 Proof ethanol products are both pharmaceutical and food grade. Everclear is a food and beverage grade ethanol that is not tested against the USP monograph.

Caution

Consuming pure grain alcohol is harmful to your health because your liver can best handle 20 -40% of alcohol present in vodka, whiskey, or rum. Examples of side effects include liver disease, nerve damage, confusion, and loss of physical control.

Use ethanol in a well-ventilated room and away from direct heat or flames. That measure prevents fire accidents because the solvent is volatile and highly flammable.

Due to several factors, 200-proof ethanol is considered better for botanical extraction than 190-proof ethanol. Here’s why:

  1. Higher purity: 200-proof ethanol is also known as 100% absolute, anhydrous, or dehydrated alcohol. It has a higher ethanol concentration, typically 99% or higher, with little to no water content. The ethanol will pick up water during the extraction process. Starting with 200 proof ensures you will get as many uses as possible of your ethanol because no water is present. 
  2. Enhanced extraction efficiency: When using 200-proof ethanol, the higher ethanol concentration helps solubilize desired compounds such as alkaloids, terpenes, and cannabinoids in botanical extracts. It improves the extraction process by efficiently dissolving these compounds, resulting in a higher-quality end product with enhanced flavor profiles and therapeutic benefits.
  3. Improved yield and consistency: Using 200-proof ethanol in botanical extraction processes can increase the yield of desired compounds and improve the consistency of the final product. The higher purity and efficient solubilization properties of 200-proof ethanol contribute to a more reliable and reproducible extraction process.

Conclusion

200 proof ethanol for extraction is the common solvent that most prefer. Manufacturers rigorously test the alcohol, thus certifying that it’s free from heavy metals such as lead, arsenic, and denaturants. Moreover, you’ll get a higher percentage of the solvent when you use 200 proof than 190 proof or Everclear ethanol.

High purity and concentration give 200 proof ethanol an edge in ethanol for extraction procedures. Thus, botanical oil and essential oil companies use the solvent to obtain fragile organic compounds such as terpenes and alkaloids. Consequently, manufacturers satisfy customers with the potent product, leading to more profits.
