Extraction Products

What To Do with Waxes Removed During Winterization?

Written by Caleb Summeril

Winterization is an important step in the process of purifying cannabis and hemp extracts. This process involves mixing crude extracts in a solvent like cold ethanol and then waiting for the lipids and waxes from the plant material to partition as insoluble solids. Once these less desirable ingredients are separated from the extract, they are filtered off and the resultant oil is a commercially viable, potent ingredient that can be used in myriad cannabis products such as tinctures, isolates, and edibles.

But can the waxes removed during winterization of hemp crude extract, for example, be used for other purposes or are they truly unwanted byproducts?

There isn’t a plethora of authoritative information out there regarding what to do with these plant waxes. Most of the suggestions found below are anecdotal and based on popular opinion/commentary. But to simply throw them away after winterization is a waste, so here are some suggestions to explore if you have substantial amounts of wax left over.

Repeat the Extraction/Winterization Process

Perhaps before giving up on the waxes as waste, one initial option is to repeat the extraction/winterization process. This can eek out additional cannabinoids, terpenes, and other desirable compounds that can be used as a separate or additional extract. Chances are, it won’t be as potent as the first pass, but an extra rinse makes sense from a practical standpoint. Think of it similarly to an additional steep of a tea bag. Measuring potency in-house offers a data-driven way to know what you’re leaving behind in the wax.

Soaps and Salves and Pomades

Another use for these waxes is to turn them into topical products such as a soap or salve. These can be fairly easy DIY experiments if you are feeling like utilizing your inner homesteader, and cannabinoid-infused topicals offer an alternate way to enjoy their many benefits while being beneficial to your skin. Soaps can be made by using a base or from scratch, and salves are wax-based topical products that are easy to attempt at home. There’s even evidence of some brands using hemp wax in hair pomades.

Eat it Up

While eating wax sounds far from appetizing, there are some people out there who suggest mixing in the remaining waxes after winterization into a variety of edibles. Some folks suggest putting them into capsules and swallowing them down or using them as a thickening agent in other cannabis-based recipes.

Ultimately, while there may not be much discussion of specific uses for hemp waxes, there are many other products designed from plant waxes, such as candles, waterproofing (e.g., surfboards), etc. As more people attempt home-based extracts and the hemp market continues to grow, there are sure to be more ways uncovered on what to do with this leftover wax. Let us know if you have any experience with this in the comments below.
