I've used the quick wash ethanol method for making smokable oil or for making concentrated green dragon. The "quick wash" part is to avoid extracting some of the bad tasting compounds from the plant, from what I understand. If I want to make oil for oral consumption (mixed with coconut oil and put into gelcaps), wouldn't it be beneficial to have a longer extraction process? I used to let batches of green dragon sit in the closet for a month or more just to extract the most I can from the plant. The only downside is the awful taste, which wouldn't matter if it's inside a pill.

I've also made batches with 99% iso (quick wash for smoking or longer extraction for oil to be consumed). For someone making smaller batches, this is much cheaper than using 190 proof Everclear. I don't think there's anything dangerous about using 99% isopropanol as long as you remove all the solvent before consuming.

still has the ill effects of chlorophyll overdose. set it in the sun while still dilute in solvent for uv degradation of chlorophyll.

THERES also a link their for the oil distiller. Cheers.

Thanks Gray Wolf- I actually have a fair bit of experience with distillation (enough to want to farm out making 190 proof- that's pretty tedious- and spend my time with rum and whiskey).

Like I said, that was hopefully an isolated incident- production had been down for weeks, they were back ordered, they may have been pushing to hard for yield, etc...

I personally would not deal with them again cause I have some bad feelings, but it is hard to imagine they could be putting out noticeably bad product for 2-3 years and stay in business.

Bazarocka- those countertop distillers are notorious for having dubious plastics in the vapor path- I'd steer clear...

They are a bit of a pain to deal with at first- you'll have to set up an account. At times they have had minimum orders, or surcharges if you don't meet the minimum.

If Alchemical Solutions is still in business, they must have cleaned up their act by now...

Nice. I see they sell in 25L size - about six and a half gallons. The 200 Proof ethyl alcohol sounds good. Do you know about how much 25L of that runs?

A shitload, I'm sure...


200 proof isn't worth the money for these purposes. EtOH absorbs H20 from the air every time it is exposed to the atmosphere, so under most conditions it won't stay 200 proof for long anyway.


Also, it is really hard to distill off that last couple of percent of water, so some processes actually add benzene to change the physical properties (although the benzene should all boil away during the distillation.

Sorry, went off on an alcohol dissertation-

-what can I say...?

I was wondering if 200 was past the point of diminishing returns. I think organic 190 proof is what I want.

I've read this before, but I've never understood it. How could someone experience ill effects from ingesting chlorophyll? Does this only affect people with certain medical conditions? You'll get more chlorophyll in a spinach salad than you'd get in a gram of "green" oil from a long extraction in 190 proof ethanol. People buy and consume chlorophyll all the time as food coloring or as a dietary supplement with no ill effects. I'd expect a high chlorophyll oil to have more health benefits than oil with the chlorophyll removed or broken down by UV light.

The final product from a longer extraction has a stronger taste than from a quick wash, but I wouldn't care about taste if I was making oil capsules.

Do you know why 200 proof ethanol is so expensive relative to 99+% isopropanol? Is the isopropanol distillation process just easier at producing a pure product than with ethanol? Does the 99% iso absorb water vapor every time it's exposed to the air too? Sorry for all the questions; I just need to get a better understanding of how this works if I'm going to be making large batches of oil.

ANY food grade ethanol is expensive relative to iso because most of what you are paying for is Federal Excise Tax- more than for the alcohol itself. It is hard to justify paying the $$ for organic food grade ethanol (or even nonorganic) when you are just going to evaporate it any way.
It is a more sustainable product though- there aren't any certified organic mom+pop isopryl distiileries!


The issues in producing 200 proof EtOH are still there when making isopropyl. The alcohols and water form an azeotrope, and the remaining water cannot be separated by distillation without adding other chemicals.

Iso is also hygroscopic (absorbs water from the air), but I think less so than ethanol.
