Raw CBD or distillate?

somewhat. Still not gonna hit 50%

@Akoyeh

The highest concentration I have formulated is 440mg/ml CBD in MCT, and it was made with lightly polished crude. I cannot speak to the shelf stability much, as the tincture was consumed by the patient within a month. There were no complaints of anything falling out of suspension, and I made that concentration for a patient until they passed.

Indeed, using crude with good waxes, one can reach somewhere around 47% without issues.

@Dr_Jebril

Later I found out that the solubility actually depends on the MCT oil composition and also on the presence of waxes. The limit of the pure CBD Isolate in the pure MCT oil I use is ~33% At room temperature (22°C). It can be increased to ~47% using hemp waxes (maybe higher). It gets 5-6% lower in other kind of oil such as olive or hempseed. The more linoleic acid the less it is soluble. Thus tuning the MCT oil C8:C10 composition may also allow to increase the solubility.

Solublity apppears also a few % lower for CBG.
I have not tried to find the limit for CBN. It is at least as soluble as CBG.

I’ve managed 400mg/ml THC in MCT, but did not explore the limits thoroughly.
