    Default DMSO not freezing

    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.
    Didn't use.

    39* is not freezing temperature, generally...

    FWIW, it was 29* in my barn this morning, and my betadine and Koppertox were not frozen either.

    Sorry, I'll clarify. Asking only about dmso which used to freeze or solidify @ 60*

    I just recently purchased a bottle, and took it to the barn to apply to geldings shoulder, and i swear, 15 minutes, at 50* and it had crystallized...i'm not sure how yours didn't freeze...bizarre

    It doesn't freeze if there are additives like cortisone or sarapin in it. Any chance that is why?

    The freezing point of DMSO is very low, and additives can most certainly change the freezing point.

    Actually it is very high, somewhere around 60 degrees.

    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.

    DMSO is exquisitely hygroscopic, which means it sucks water out of the air.
    I'd bet that it's water lowering the freezing point.

    Glad to hear it's a bad bottle-thought maybe they had "changed" to make more user friendly. Not mixed w/ anything why I fully expected the need to "heat to use"
    Thanks
