Raw CBD or distillate?

[V1thc]

Hello
Which is better for producing CBD oil, distillate or raw CBD? Is it possible to obtain 60% CBD oil?

[RockSteady]

CBD distillate is produced via the fractional distillation of a crude hemp extract.
CBD crude is typically 60-75%.

[V1thc]

Which of these products will be better for producing CBD oil?

[RockSteady]

what are you trying to do with it? what kinda products are you making.

typically you cant go wrong with a distillate

[V1thc]

I want to make CBD oil in drops 5%, 10%, 15%, 30%, 50%

[RockSteady]

like an MCT tincture or something?

CBD isolate would be the easiest to formulate with unless your going for a broader spectrum of active compounds in the tincture then distillate is your best bet.

[V1thc]

and raw CBD will not be good for this solution?

[RockSteady]

yeah if you wanted to emulate an “RSO” like broad spectrum product you most certainly could. just make sure you find really nice crude there’s a ton of garbage out there. ask to see residual solvent testing; if ya see any solvents besides ethanol; i would find a different supplier with cleaner crude.

What your inputs are completely depend on what the goal of your final product is.

Thank you very much for your help!
If I use a rock-hard distillate and dissolve it in hemp seed oil, will it not crystallize in the oil over time?
The picture shows the distillate that I can buy

You don’t have to worry about the CBD redissolving once you get down to 50-60% Since your drops are 50% and lower you don’t need to worry about it, just do a good job of melting your CBD so it dissolves in your carrier.

The solubility limit of CBD in hemp seed oil is about 28%. You may increase that a bit by adding CBDa.

[V1thc]

Does MCT oil have a higher solubility limit?

[cyclopath]

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.

@Dr_Jebril

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.

Thank you for your help

[lolwut]

400mg/ml? Were you making tincture for an elephant? 400mg oral THC just sounds uncomfortable

[cyclopath]

Yep, 400mg would definitely be in my “uncomfortable “ range.

How many drops in a ml?

[lolwut]

20, gotcha. Just a drop or 2 then eh?

@cyclopath

400mg/ml THC in MCT

What happens once over that treshhold
I mean they are both oils so think they would yust mix !
Folks cut their carts with 10-15 % so
See no reason any concentration of either gives isseus THC that is not cbd

[cyclopath]

Fair enough.

No clue.

That was about as concentrated as I could get it…I admit I was in a hurry, and aiming at a specific viscosity, so your mileage may vary.

@cyclopath

I used MCT last time I played this game. at 400-500mg/ml cannabinoids…getting 150ml past customs as “bicycle chain lube” worked like a charm…but I ended up adding it to my coffee rather than vaping it, because vaping MCT sucks.
