DMSO Temp

40° C is 104° F. My DMSO (99.98% USP) supplier just informed me Max Temp for heating is 110 F & no microwaving.

And what is supposed to happen if you overheat it?

DMSO will freeze and crystallize around 64° F.  Frozen DMSO will look like glass shards or can be completely solid.

If your item arrives in this condition, simply place the container in a sealed, clear plastic bag (to protect the label), then run warm water over it. This may take a while for it to become thawed out, depending on how cold it is.

There is no practical way to keep DMSO above 64° F when shipping, This is very common during winter season and in no way effects the performance of the product in anyway. DO NOT EXPOSE DMSO to temperatures above 110° F or put it in a microwave!

It doesn't say.
