RSO 2.0 2022 - A Revolution in making oil at home.

1 November 2022

RSO 2.0 2022 - A Revolution Has Arrived in Making Cleaner Oil Easier, Faster and Cheaper.

In the early 2000’s, Rick Simpson brought the healing quality of cannabis oil to the masses using simple extraction techniques. In the larger picture of extraction processes, this methodology is simple and oils are crude. Crude No Longer!

Today, CHS is ecstatic to announce RSO 2.0 2022, a radically different approach in making oil at home. This update contains TWO recent discoveries enabled through Isopropyl Alcohol's Super Power. This unique characteristic, only found in Isopropyl, allows Brine water to separate unwanted compounds just by mixing the two liquids together! Take a look -

Discovery #1 - Brine Isopropyl Degumming

Here's what is happening in the above video -

By pouring fully saturated salt water into Isopropyl Alcohol, the alcohol loses its ionic bonding to water and the two separate into layers. This is called 'Salting-Out Isopropyl' and is very well known high school chemistry experiment. Salting-Out Isopropyl removes excess water, but it also frees up all other molecules dissolved by the alcohol. Picture the molecular world freed and now dancing in a big game of Musical Chairs except when the music stops, molecules tend to bond with similar molecules creating pure crystals. This pure crystallization of phospholipids is what you are seeing as a snow blizzard in the water layer.

Now for the first time ever, damaging phospholipids can easily be separated out of the oil. Phospholipids are responsible for locking impurities into the oil. Using this technique, phospholipids can literally be shaken free of the oil.

Introducing 'Silting'

Silting is a comprehensive cleaning step that works at multiple levels. Dividing the wash in two separate layers by Salting-Out the isopropyl is a great tool for cleaning out unwanted compounds.

  • The brine vacuums up all water soluble compounds, both polar and semi-polar. Acids, sugars and water soluble impurities are drawn out of the alcohol into the water.

  • Brine in conjunction with water distilling (the next step..) also deodorizes the oil. It smells and tastes more like oil..

  • Room temperature soaks can now be cleaned up.

  • There are two forms of phospholipids removed in this step. The two forms are water loving (hydratable) and water hating (non-hydratable). Adding the brine isolates the water loving phospholipids. By adding 1 milliliter of lime juice, the water hating phospholipids dissolve into Free Fatty Acids and Glycol.

  • No more filtering out trichome shells through paper coffee filters as the trichome shells sink into the water.

  • 99% Isopropyl is prefered but 91% Isopropyl works very well. Alcohol recovery and recycling further reduce costs.

Discovery #2 - Rapid Winterization

Brine Isopropyl Degumming purifies the oil by removing polar and most semi-polar compounds leaving lipids in high concentration. The term 'Lipids' is simply the family name for oils, fats, phospholipids and waxes. Using Isopropyl for the bulk solvent sets up a unique condition due to it being less polar than ethanol. Once distilling is done, the waste water dumped out, ethanol is used to redissolve the oils for the final reduction. Here's where the magic happens. Ethanol's higher polarity causes the liquefied waxes to be repelled. These repelling forces cause the waxes to compress into smaller spaces, even at room temperature. By placing the ethanol wash in the freezer for 10 minutes, the waxes accumulate into clumps, easily caught in a paper napkin. A simple folded napkin is all that is needed to catch a majority of the waxes.

Steps in making RSO

#1 - WASH. Wash the plant material in 99% Isopropyl Alcohol.

#2 - SILTING. All the magic explained above.

#3 - DISTILL. Remove the alcohol, collect the oil.

#4 - WINTERIZE. Separate out waxes with cold temperatures.

#5 - REDUCE. Reduce one last time to final oil.

    1. Brine enables low heat extractions for saving terpenes and avoiding unintentional decarbing. Extractions can now be made across a wide range of temperatures starting as low as 65c/150f and upwards to 100c/212f.

    2. Water-soluble plant compounds, sugars, etc., are absorbed in the Brine. These compounds historically have been boiled into the RSO.

    3. Residual Isopropyl is completely removed, first through distillation, then completely in the final reduction.

    4. A common problem while distilling is 'burning' the oil on high heat devices (IE, the use of water distillers). This never happens now as the oil floats on top of the water. The water buffers the oil from hot metal surfaces. Once the alcohol boils off, oil and water naturally separate making recovery easy.

    5. Burning the oil in the final reduction remains a concern. Temperatures must reach at least 100c/212f in order to remove all water content. Once the water boils off, the heat immediately spikes, evidenced by the presence of smoke. The solution? Using a double boiler setup with Brine in the base boiler.


The introduction of Brine makes the use of Isopropyl Alcohol safe for home extraction. This in turn significantly reduces the costs of making oil. Salt in the final oil is avoided because oil and salt don't mix just like oil and water don't mix. Steps are taken to wash any residual salts out of the oil after distillation. Overall, there are now five steps to make oil. Each step is presented in video with descriptive captions of the technique. This new technique is presented in a Quick Start guide, found below. A more complete ‘RSO 2.0 Shop Manual’ will soon be available for a deeper exploration of each step. Yields are close to the original but may be decreased as much as 1/4th from what is normally expected. This makes sense when the trash is removed, the volume goes down, but the concentration goes up. Trading off junk for higher purity is a good trade.

Making RSO The New Way

Here's a demonstration video showing how to make cleaner oil in just over an hour. This demo extracts oil from 2oz of hemp trim and delivered 3.77ml of oil in the final reduction.

WARNING: Never distill alcohol near open flame. Alcohol vapors are highly flammable so always distill in well ventilated spaces.

This oil is appropriate for oral ingesting and vaping. Due to the potential of residual salts, do not torch this oil. Torch temperatures can reach over 760c/1400f and can vaporize any residual salts.
