Anyone else have this happen.
Was 39* in barn this morning, expected dmso to be frozen both the liquid and gel were still in original form. One bottle 4 mnths the other one 2 weeks old.
Have they changed something- or I just lucked out w/ bad batch.
DMSO should freeze reliably in the fridge (around 4 degrees C). "Officially" it should freeze at 18 deg C (60 deg F). It shouldn't necessarily matter what's added to it---if something is added to it to change the freezing temp, it would likely only raise it a few degrees if anything.
The good thing about freezing DMSO in the fridge, is that it will thaw in whatever "external temp" you remove it to, unless of course the outside is colder than your fridge. LOL

Only pure DMSO freezes at 60 degrees. The gels and roll ons and pastes and various formulations made to be easier to handle are not "pure", strictly speaking, and would have a much lower freezing point. This is probably on purpose, since frozen DMSO is not very useful.
If the bottle is actually the pure stuff and is not freezing like it used to, I'd chuck it. One of the properties of DMSO is its ability to adsorb other substances, and as it also carries whatever's mixed with it readily across the skin, I would not want to use a bottle that's contaminated.
