Benzalconium chloride

[Biohpilic]

Hi guys,

I've been reading these forums for a while and for the first time I can't find the answer to my question, so I decided to post it.

The thing is, i have recently done a couple of runs of QWIso and I was stupid enough to use pharmaceutical iso alcohol, which has 0.1g/100ml of benzalkonium chloride. I realized a couple of days ago and after researching a little bit I found that it is slightly toxic to mammals and thought I would have to toss it. However, I found today that its flash point is 250C, so I should be ok vaping it at or below 210C right?

Any info is greatly appreciated!

Wiki says 250C if solvent based. I wouldn't mess with it imo. Possibly redissolve it in solvent and then try and flash it off, but not sure how you would get up high enough to remove it and still have any solvent left.

Good luck!

It is listed as a mutagen and reproductive system toxin, so I would advise against using it.

Thanks a lot for the answers guys,

Ill obviously not be using that same alcohol for future extractions, I have found a couple of places where they sell pure ethanol, so ill be switching to qwet next time. But for this time should I toss out the 0.5-1g that I got from the last runs? I mean, i dont like that it is mutagenic, but this stuff is used in every contact lens solution and on eye drops among other things, so isnt there a safe way to consume it like making cannabutter or vaping it?

Thanks again!

How most first and second posts look after a while, nothing you can do about it:

"Hi! I work for a syndicate and we can't give away our harsh overfert buds, but extracting really cuts into our profits! Can we QWISO with the cheapest rubbing alcohol we can find on plants that are already full of miticide and fungicide?"

It doesn't help that the connection to this chemical and a word like lung is missed or ignored. The best hope is dissolving in nonpolar solvent like heptane and trying to wash contamination out with water several times, but in reality this would either give a bad emulsion or a questionable product.

Edibles: is that chemical allowed in foods - Y/N. If it's only a gram, you shouldn't have a problem with tossing it out.

Thanks a lot for your answers guys, I wish I had known before.

GrayWolf, you have been an amazing resource for me when researching both here and at skunk pharm. Your webpage is extremely useful and has a lot of great info on it, so I wouldn't like to offend you or anything, but maybe you could include some info about what kind of alcohol should be used on the qwiso page, as you did on your bho article, which was extremely useful too.

There it goes, a gram of superskunk qwiso shatter to the trash!

no iso at all man.. use straight ethanol.. everclear 190 proof.

any grain alcohol over 180 proof will work fine.. the more water the more water solubles to be picked up.

i know people like to get the cheap shit to do extracts.. but if u want cheap . grab some power 5x.. thats safer then ISO

 

[JointOperation]

1 thing i know is . no flourides or chlorides lol.

 

[Biohpilic]

Yeah, next time I'll buy pure ethanol, I found a place where I can get a L for about 25-30 bucks.

I did a little more research and I found that benzalkonium chloride's boiling point is actually below 40C, so what if I decarboxylate it at like 120C? will it still make me grow a third lung if I smoke it?

 

[G.O. Joe]

benzalkonium chloride's boiling point is actually below 40C

Any organic chemist would glance at the structure, then say that's impossible. Sorry, it will not boil out for you, and you have bad information. How does the resin taste?

It doesn't taste bad at all. I decarbed it yesterday at 120C for 20' and after I took a dab i can say it still is very potent, it might taste a little bit more like vaped bud than before, and definitely tastes less than the original product, but it tastes kind of like every other oil i've tried. The hit is very potent, it expands in my lungs about a minute after the dab and usually makes me cough, but this might be because i'm just not used to dabbing.

I did a little more research and found that the melting point is the one below 40C, and the boiling point is actually around the 130-150C mark, which makes sense considering it is a 9 carbons chain. I'll decarb it again at 160C for a few minutes.

By the way, I don't think I'll smoke it in the end, but i just dont want to throw it away and i thought it would be interesting to experiment woth decarboxilation, and maybe try to get different textures from the oil, as well as study the changes in taste and smothness.

It has 18-28 C's - that R means more C and H. It's a quat salt. It isn't volatile. .

 

[Biohpilic]

You're totally right, I didn't see the R group. I guess I should stop doing these vital kind of things while being extremely high...
So, what does the fact that it's not volatile mean? It must have a melting and a boiling point anyway right? And if it isn't volatile why is it risky to vaporize it?

Hey guys, sorry to be annoying, but it just hurts so much to throw away such a nice looking extraction. I'm thinking about decarbing it at 160C and vaporizing it at 200C, leaving a 40C window for the benzalkonium to evaporate. I mean, either it boils at some point, and I would say before 160C, or it doesn't boil at all, in which case it wouldn't evaporate at 200C either. Am I correct?

Not sure how to answer you other than point out again that it is a known mutagen and reproductive system toxin. How much is too much?

It was used because it is difficult to remove and unpleasant enough to dissuade alcoholics seasoned and desperate enough to drink isopropyl alcohol.

How desperate are you feeling, and willing to gamble?

Is this for you or some one else?

Benzalkonium chloride (BC) is soluble in water but not ether.

You can try to wash out the BC by dissolving your oil in ether then washing multiple times with water. BC will prefer the aqueous phase so you can discard the BC with the water, keeping the ether phase. Then all you have to do is remove the ether to get your oil back. Don't use lowgrade ether or else you are likely switching one contaminant (BC) with another (whatever's in technical grade ether.)

So did you iso say it contains it?

Looking at MSDN sheets of the ISO they sell locally and it isn't listed as an ingredient.

99 iso....1%water
or 91 iso....9% water

Nothing else as far as I can see.

The only thing with benzalkonium chloride are antiseptic wipes etc.....

 

[flatslabs]

Lab grade isopropyl that I have seen is ~100% in the MSDS not accounting for the denaturing products, but certainly doesn't contain benzalkonium chloride.

I suspect OP is not telling the complete story, and actually used some type of lab grade sanitizing solution for cleaning surfaces, contact lenses, or hands. Something like Sterillium.
