Iso stinks

I just made som QWISO using isoproprylalcohol and I love the color -brown.
It´s still needs to evaporate some but it stinks of naphtalin.Why? Nothing is added, it´s pure ISO. Should I redisolve with ethanol? Doesn´t Iso brake down to carbondioxide and water?

No napthalene (C10H8-Mothballs smell) in ISO, so not sure where it might have come from. Are you sure it is napthalene?

Isopropyl doesn't break down in this process, it just evaporates. If burned it would break down into CO2 and water.

My side is that in Finland we have no good quality ISO(there is some dirt on it)

Thats why i havent try it myself, but i have seen it failing many times.

They sometimes add lanolin to the lower concentrations isopropyl rubbing alcohols here in the colonies, but not to 99%.

The iso should be pure, no mention on the bottle of any additives. The smell is sort of like gasoline/nafta but iso also doesn´t smell like ethanol. It´s pretty much evaporated now and it´s looking good...I guess it won´t kill me eh?

Yeah, Isopropyl alcohol is pungent and doesn't smell much like anything but Isopropyl alcohol. Not even the Propyl alcohol, that is an isomer of.

Both are based on the propane alkane molecule, with the addition of a single oxygen molecule, but even propane doesn't taste or smell like naphtha, so the origin of your odor and taste is still a mystery.

If you Google the brand of Iso that you used and add MSDS, you can get a list of ingredients that are not necessarily required to be on the label. You might give that a try.

You can smell and taste Isopropyl well before it reaches threshold limit values, so I guess it depends on just how much is left as to the effects, but death is unlikely. Unlike playing with yourself or drinking Methanol, you are more likely to go deaf than blind first.

If you are smoking or vaporizing, if you keep your oil above 180F in something with a large surface to depth ratio, like a Pyrex pie plate, the oil will be molten and the alcohol will exit faster.

If you are going to consume it orally, you want it decarboxylated anyway, so if you put the oil container in a pot of 250F oil until the big bubbles are gone and the small bubbles suddenly drop significantly, the Iso will be significantly below TLV.

Lovely comment!

It´s pretty much evapurated now, I wonder if I should just let it dry out? I was hoping on some "goo" to brush on my joints but I guess I can redissolve it in ethanol later on.

My dry humor, that not every one appreciates and a play on Isopropyl poisoning sometimes attacking the auditory nerves, while Methanol poisoning can cause blindness.

If it is an ISO extraction and isn't pretty stiff, you most likely still have alcohol left in it.

You haven't mentioned what percent ISO you used. If it was less than 99%, it may also have some water in it.

Hi, This should be 99% so I´m on the right track -I hope. I had it on the radiator awhile and not much liguid left, dark brown color, looks like chocolate!

I guess I´ll give it a rip tomorrow...could you speak a bit lowder please ;)

i put mine in an oil bath to be sure.

other thoughts?

I ended up drying the last moisture out in the oven at 150C but with the door open. It bublled out nicely and left som dark brown/red "oil". I then popped it in the freezer and this morning I scraped it a bit andit peeled of nicely even though it still is a bit soft even after the freezer -it´s back inthere now "freeze drying". The smell still isn´t clearly cannabis and I´m starting to wonder if the smell could also be affected by the strain, I used Thyphoon from an outdoor grow, good quality, and I used maybe 30gr that I ground up and let the iso cover it plus about 2cm extra.

Whatever is left in it should be smokeable.

More thoughts?

i do strain specific oils. they all have their own aroma and flavor.

The only time my ISO has ever turned out good is when I used it to clean my grinder and vaporizer. Whenever more plant material has been involved it has turned out to taste and smell really horrible. I have only used trim and/or fans though. Haven't had the heart to use buds.

Doing the whole process really fast is supposed to produce good quality (hence the "quick" in quick wash iso). I've tried to be fast but I guess I just haven't succeeded in being fast enough. Since you mention that you somehow submerged the buds in alcohol I have a feeling the same may be true with you (my methods have been similar). If you still have some material to work with you might want to try putting it in some kind of tube and having the alcohol just quickly run through it, this may improve quality.

But you know, there is a reason why all the "errl heads" use butane despite it being hella-expensive and hella-dangerous. ISO stinks.

Errl head? Now where have I heard that?

After heating, freezing, drying and one last freezeing I still have a tarlike substance -except itś like darkbrown. The smell of the goop is still of petrol or something and the ISO I used (whatś left of it) still smells of ISO. Weird.

Have you tried any of the above suggestions?

GW: I´ve tried it all -except smoking it. What is this supposed to smell like? The last batch I made was coal black, brittle, and tasted like hell when I tried it but that was made from recycled trim (first bubblebags then QWISO -not recommended) and this was good bud.
