Should I be concerned about storing my DMSO?

Hi Ted,

I just ordered the DMSO. I've been concerned about storing this product in its plastic container, since it's a solvent and might pick up some of the plastic. I transferred my last batch to a glass jar. Do you think there's any basis for concern?


Greetings Bob,

The very special type of plastic used for the last 40 years by Jacob Labs as the primary container to store and deliver their various DMSO products is a laboratory grade of polyethylene; this is not your garden variety plastic.   As you correctly point out, DMSO will leach and transport many polymers and chemical elements if it is kept in the wrong kind of plastic container.  This is a subject I covered with the Jacob Lab people over 10 years ago when we first started to work together to develop a Peyronies treatment protocol.   Dr. Stanley Jacobs is a medical doctor, as well as a teaching and research professor at Washington State University, and he gave me his complete assurance that this more costly container is completely safe to transport and store DMSO.

Personally, I would be more worried about the DMSO picking up the residue of what used to be in your glass jar (mayonnaise, spices, even the soap you washed the jar with, etc.) and getting into your tissue, than anything from the original polyethylene container the DMSO comes in.

    If you are going to use DMSO for Peyronie’s disease treatment you can extend storage by using refrigeration. Freezing point of DMSO is 65.3 °F so you can insure your DMSO by putting it in a refrigerator and it should be solid with out any liquid, just sit it with your milk and juice. Once solid it should last forever. It is more or less like a block of wood or ice. Ice never goes bad.

    Greetings Ed,

    Thanks for your thoughtful comments about Peyronie’s disease treatment and DMSO storage.

    While what you say is true, our interest is not so much storage of DMSO, but using it. As a matter of fact when we get a shipment of it from the laboratory where it is made, each bottle of DMSO can be frozen solid when the temperature dips into the 60s and below.

    The average man uses his PMD DMSO twice a day; a few men use it three times daily and some men only once a day. So you can see that keeping DMSO in the refrigerator would not be helpful during active Peyronie’s disease treatment since it would be inconvenient to thaw it out so often. Using just a few drops a day, the typical person finds that his four-ounce DMSO bottle will usually last 2-3 months before it is used up. If the Peyronie’s disease treatment plan is being conducted properly storage should never be an issue since when you receive it from PDI the DMSO is never more than a month or two old. It is as fresh as it can be. TRH
