Activated carbon for bleaching and deodorizing of oleo-resin tinctures to produce high quality concentrates.

Pictures are of a control sample followed by the application of our carbon on a cold solution at 3% concentration w/w for 30 minutes.  This carbon can be used hot or cold and your residence time and concentration must be adjusted so your results will vary. 

This product is not acid activated so will not cause isomerization.  This product is not classified as food grade so must be fully recovered from your solution through filtration or on the boiling flask.  

Activated Carbon is used everywhere in industry to remove smells from the air and contaminants from liquids and has thousands of applications.  Carbon is dependent on what it is made from (wood, coconut, etc...), how it is made active (fire, chemicals), and what size it is ground to, among other factors.

We reached out to the top carbon companies in the US and asked what could work for our application, most provided dozens of possible samples as there is no research available for this industry for the use of this product.  We took those samples and did lab tests using different sizes and types of carbon, applied them to our tincture in different concentrations, we agitated all those at different temperatures for different times.  Dozens of tests later we chose the carbon that had the best results and thus offer it here for this application.

We looked for a carbon that was inexpensive, easy to use, reacted fast, and removed most of the contaminants possible without removing the compounds we need.

All filter media including this product will tend to capture some of the molecules you are looking for how ever little, this is just a fact unfortunately.  Cold solutions will capture more of those molecules while hot solutions especially those suspended in ethanol will strip those molecules.  At hot temperatures, heavy metals and pesticides absorbed will strip, negating the benefits of the carbon. Chlorophyll will generally be difficult to strip at any temperature.  We recommend room temperature agitation to perform adsorption, a good balance to remove odors, color and contaminants. 

We sell this product in various sizes by weigh, with price breaks the more you buy.  This product is intended for single use, and is meant to be discarded after each use.  This product will react with your tincture and actual results will depend to the quality of the starting material.  The key to a clear oil is good starting material, but as important is proper equipment and operating procedures and know how.

Depending on the quality of your crude, the typical dosage is 1-3% by volume.  To be used on solvent/crude mixture, not pure crude.  Always use as little as possible and we recommend you do lab tests to determine the correct amount to use.  Recommended agitation time and temperature also is debatable but generally 10-30 mins agitation is ideal at room temperature.  We do not recommend using carbon on a warm solvent as carbon tends to strip with warm ethanol.  Many will debate this but we feel heat is unnecessary and probably detrimental.

If you need help with this process we would gladly refer you to a consultant to develop an SOP for your company.
