Anybody in Cali notice that all/alot of the thca isolate is popping for Chlorfenapyr… wondering why it seems like everyones running dirty product, or that no one is performing flushes on their system after running dirty material. Any ideas??

It’s a easy fix
Im listening…
Seems to have been in the market in California for a while now, like many years. And certainly alive in the news in the last 6 months due to the recalls.
Are you pretesting all the flower you are running?
Do you already have methods for cleaning out your systems?
Are you buying material from someone else that is contaminated?
This stuff is used widely around the country for mosquito prevention, even if its not used in California (because they have different rules…).
So if you are getting material that isn’t from California, you might be seeing other issues as well.
There are some activated charcoal products which have been designed for Chlorfenapyr remediation.
And its also worth noting that Chlorfenapyr likes to stick around in soils long after plants are harvested. And that there are many plants (could cannabis be among them?) that are hyperaccumulators. There’s even plants being used to remediate contaminated soils, you know?

Ive had a few people tell me they have popped for this pesticide. When doing the research it is a powder with a melting point of 100c. There is a possibility it is cold crashing out with the thca.
Very likely as it seems to be heavier than thca

Yep. I saw it. Glob helped fix It. Dumb easy solution. But, for him to tell, not me.
Few are the contaminants that can’t be removed with a few ReXs…

Its been from material thats supposed to be for Cali legal market, weve had a few different processors/suppliers pop for it in last month. Just seems weird that so many people in legal market are running material with chlorfenapyr.
One of the cases even happened with some of our biomass we had another company toll, seems like it was hung up in their system.
Weve remiediated plenty of pesticides in past just annoying to have to remiediate something that was supposed to be a finished product.
Anyone have any info on how to remediate it out of isolate? I was thinking of re-dissolving it and running it though a large silica bed? If anyone has any more info id appreciate it. kind of weird to be gatekeeping pesticide removal. Thank you!
Unless you tag or reply to the person(s) you believe is/are gatekeeping…they won’t be notified.
As it stands you’ve notified the OP.
Chromatography is certainly a viable option, so long as you understand taking and testing fractions.
You might find that the advice listed up thread is at least as viable.
Just search it. That hit shows bentonite as another remediation route. It’s ill-advised to use UV treatment or distillation to purify due to degradation products being unsafe, despite passing testing.
I usually try to search all the info i can before posting something like this.
I am trying to not redissolve the isolate if possible.
I have seen 0 answers from people that tried the said remediations of the ideas given. I was looking for a straight forward answer. If anyone else can help Id appreciate it. Thank you all.

I ran into a bunch of chlorfenapyr last month, had like 2,000lbs of material that kept popping for it. High amounts. After trying a few things, i found the best thing to help was to redisolve in butane and recrash. After i started doing that i was non-detect for the rest of the lot. I would crash it, take it out, put into a jacketed column with heat, add butane, let it redisolve completely and put back into the crash column. No eztra media or crc needed. Hope this helps!

Thanks for the reply !
Yep. As @MagisterChemist pointed out:
It’s built into the process, and has been used as purification for hundreds if not thousands of compounds.
Thanks for providing @Terpjesus with the first hand report they desired.
Pretty sure @globtek33 would have provided confirmation if they’ed actually seen @RockSteady’s post…ReX is one of his specialties.
But then is it in the butane ? I have mine setup with a crc with some carbon and silica after the wash
“In the butane?” Sort of…
In general terms, most pesticides are not going to make it back through two phase changes into your solvent tank, but you do want there to be liquid left for it to “be in” when you pull (then spin or rinse) your solids. If you pull ALL the solvent, your contaminants have nowhere to go but precipitation…
Sacrificing some cannabinoids is required if you’re leaving a liquid fraction.
Once you’ve crashed and separated, you should be able to recover the rest of your solvent, and clean your evaporator with something appropriate to the contaminant(s).
Using bentonite or activated carbon is another route that gives your contaminant somewhere else to be.
