CBDA Water Extraction vs Solvent Extraction

What is CBDa water extraction? Water extraction is a chemical free extraction method to retrieve oils like CBDa, CBD, hemp oil, and fragrant essential oils from plants, without using chemical solvents. CBDa water extraction works by soaking the hemp plant in boiling water. The heat from the boiling process pulls the oil out of the flower, while the water protects the oil from burning. This liquid is now set to cool, and as the water and oil cool, they separate from one another. Once separated, the CBDA oil can be collected. This process is known as CBDa water extraction, and requires W.E.T, (water extraction technology) to be properly executed.

Another extraction process used to obtain CBD, CBDa, and other plant oils is called solvent extraction. Solvent extraction is one of the more popular forms of oil extraction as it is fast, and can easily pull out large amounts of oil from plants. This method is used for extracting cooking oils from nuts and seed, as well as oils like CBDa or CBD from hemp plants. This extraction process involves soaking the plant in a solvent like hexane. The hexane effectively retrieves oils from the plant, and then quickly evaporates, leaving behind just the plant oil.

CBDa Water Extraction vs Solvent Extraction:

  • Speed – Solvent extraction will typically be faster as extraction solvents like hexane or alcohol have very fast evaporation rates. 
  • Safety – CBDa water extraction does not require the use of chemical solvents, however both methods are safe to use for oils that will be ingested or used on the body as solvents will completely evaporate from the oil product, leaving behind a pure, safe oil.
  • Extraction Amount – Solvent extraction is great for retrieving oil from plants that do not produce much oil, or are hard to draw oil out of. Solvents like hexane can effectively retrieve the maximum amount of oil from the organic material. Water extraction is better suited for organic materials that have a high natural oil content, that do not need much help producing oil for extraction.

Can You Use Hexane For Oil Extraction?

If you work in an industry that extracts oils from plant materials, you may want to look into hexane for oil extraction. Oil extraction is a process that uses a chemical solvent and heat to extract the oils from various nuts, seeds, or plants to create products such as CBD oil, sunflower oil, olive oil, or canola oil. There are many methods of extraction such as pressing or steam extraction, but a common method used today is solvent extraction. In this method of oil extraction, a low toxicity chemical solvent, such as hexane, is mixed with the product that oil is being extracted from.  The plant product sits soaking in the solvent allowing the solvent to pull the oil from the seed or plant. After the oil has been successfully extracted, heat is applied to boil the solvent and plant mixture, allowing the chemical solvent to evaporate, leaving behind a plant oil. If you are looking for a safe, easy to use chemical solvent for extraction processes like these, hexane may be exactly what you need. 

Why Is Hexane A Good Solvent For Oil Extraction? 

  • Hexane is low toxicity, making it safe to use when extracting oils for consumer use, and it does not produce any strong odors or toxic fumes. Hexane also causes less irritation to users when compared to other chemical solvents.
  • Hexane has a low boiling point. Boiling can occur between 50 – 70 degrees celsius which allows for quick and easy evaporation of the solvent.
  • Hexane can naturally pull more oil out of plant products than other solvents like ether or ethyl acetate, without disturbing the nutritional value of the plant’s natural oil.

Hexane for oil extraction is a great alternative to other more volatile solvents. If you could benefit from implementing the use of hexane for extraction you should contact us today or shop our hexane products here.

What Are The Best Solvents For Oil Extraction?

Before diving into the best solvents for oil extraction, you should understand the solvent extraction process. Oil extraction is simply the process of pulling oil out of plants like seeds or nuts, that produce consumer products such as olive oil, cbd oil, sunflower oil, and many others. There are several methods of extraction that involve processes such as pressing, squeezing, or steaming the subject to extract oil, but one of the most efficient and cost effective methods is solvent extraction. In this process a low VOC or low toxicity solvent is mixed with the plant product to extract oil. The mixture of the solvent and plant oil is then boiled, allowing the solvent to evaporate, leaving behind just the plant oil products. There are several types of low VOC solvents that can be used for this process, each with their own benefits, and it is important to understand the differences before purchasing a large solvent supply.

Safe Solvents for Oil Extraction:

  • Acetone – Acetone is a potent solvent that dissolves and extracts with ease, and it’s high evaporation rate expedites the evaporation portion of the extraction process, sometimes eliminating the need to use heat.
  • Hexane – Hexane is a popular solvent for extraction as it has a very low VOC, is safe to be used with goods produced for consumption, and it produces no foul odor or poisonous fumes. All of this coupled with hexane’s low boiling point, it is considered a safe, fast, easy to use solvent for extraction.
  • Isopropyl Alcohol – IPA is also a low VOC solvent, making it ideal for extraction. IPA is also less flammable when compared to similar solvents used for extraction and in concentrations of 95% or higher, yields more oil than other, weaker solvents.
