Hello, this is my first attempt at winterization. I put 7-10 grams of wax into iso 99, dissolved it and let it set in the freezer overnight, probably 18-20 hours now. My question is should there be a gathering of particles and frozen chunks at the bottom by now? I read it takes 24-48 hours and was curious if there should at least be a little bit of a reaction occuring by now. Thanks for taking a look and showing an old dog some new tricks

Iso is not as polar as ethanol so it fails to winterize well.

A lot have people have used it fine.
I like looking at a polarity index for this sort of thing. Butane bout 0. Water is about 10, ethanol about 5 and iso about 4. The difference isn't great and gives good results, the fats and waxes have to dissolve in anyway the chilling then lowers solubility
More important was the temp and amount used before it went into solution and chilled

polarity index
Iso = 3.9
Etoh = 5.2 (significantly improves results)
Iso = 3.9
Etoh = 5.2 (significantly improves results)
Thanks for the replies, good information to have. Ill try ethanol next time. I used the iso99 becuase i had it on hand and had seen other threads about using it.
It put 7-10 grams of the remaining wax i had into a jar of iso99. The wax had been in a heat vac for about 4 days and had a tough carmel or taffy like consistancy. The iso99 was room temp and 9oz or so was used. It had been in the freezer approx 24 hours now. I was curious if i should be seeing any kind of a reaction by now ? There is a few debris particles at the bottom of the jar but nothing substantial, 5-6 particles maybe. Is there anything else i can do to help this process along?

I wouldn't vacuum purge bho that will be winterized, rather in leiu of the vacuum chamber I would dissolve in warm (90f) ethanol and let the rest of the butane fizz off before freezing.

How cold is the freezer? 0F?
Im not sure of the freezer temp but i just checked the jar and there is now quite a few white colored particles at the bottom of the jar. Ill let it set one more day just to be safe but i think it may now be taking effect. I have 3 questions tho if you dont mind me asking.
1) can a throw in another 14 g into this jar ?
2) what is the correct amount of liquid to use per oz of wax?
3) if i were to skip the first vac and use the ethanol to purge off the butane as mentioned above, would i then use the vac in the last step in order to purge off the ethanol as well as give a good consistancy to the product? Basically im curious that since the butane is gone id just be pulling to make it a wax or shatter or whatever and get rid if any leftover ethanol right? Thanks in advance

12:1 ratio is best. The solvent needs to flow like water when laden with bho @ 0f.
Only need to vacuum purge if the film is thick using etoh.
No point in vac purging 2x.

I usually look at dielectric constants, such as shown in the attached chart. The break line between polar and non polar is generally accepted as being 15, with n-Butane not shown, but at about 1.34.
Note Methanol at 32.7, Ethanol at 24.5, and Isopropyl at 17.9, barely making the polarity cut.
You can winterize with any of them, given the spread from 1.34 to even 17.9, but Methanol does the best job, and Isopropyl the least.
PS: Highly polar, water is at about 80.1.

What SP says about skipping the butane purge if you are winterizing.

My point was that, on your preferred scale etoh is only about 6.5 points higher than iso. Etoh not exactly being all that polar either, both can winterize fine
It does not "fail to winterize well"
And the higher the polarity doesn't necessarily mean better or we would be using that highly polar water mentioned. This is why I said temp and amount used has much more to do with it
