In addition to making distillate from scratch using flower/shake, we are doing pesticide/insecticide/fungicide remediation on first path SPD distillate for a number of our customers.
Our goal is to produce a medicine like Rick Simpson Oil without any toxins so it will pass the new California BCC regulations while minimizing our material loss during the remediation process.
We are experiencing a larger than acceptable loss of material during our process. We are seeking input in refining our current SOP for pesticide remediation to reduce loss of material.
We start with a clear, pale yellow, oleoresin that requires pesticide remediation to meet the new CA regulations.
Our current SOP for removing pesticides from this clear Oleoresin is as follows:
-
We start by dissolving the Oleoresin in Heptane in a 4:1 ratio.
-
We then brine wash the solution per the SOP published in the Acron Journal for remediation of pesticides. We are using a 50 liter reactor from Lab Society/Across International for this purpose.
-
We use CBleach per the Columbo Labs SOP for Wet Bleaching.
- Our question here is whether or not this step necessary since the color of the starting material is very good?
- Secondly, could we just use the Activated Carbon portion and avoid the loss of product due to the use of CBleach?
- We then use a Chromatography Column filled with MagSil to filter the solution. We use a 1:1 ratio of 1 gram Oleoresin to 1 gram of Magsil
- Is this too much? We have read that you used a 4:1 ratio of Oleoresin to Magsil. Did you have good results?
Thank you for you assistance in this matter.
