There are 2 grades of DMSO.
Medical and Industrial.

If you have DMSO that smells, flush it down the toilet
and get the Medical grade that is colorless an odorless.

Hi jbnet,

I would be interested to know where you got your info about DMSO. It is something I have investigated and as far as I have been able to learn, Gaylord is the only producer making true USP (US pharmacopia) grade DMSO and they won't let you buy it unless you are a doctor or a drug manufacturer. The manager I spoke with there also said the wholesale cost is about 10 times more than the other grades. You can go to the Gaylord LLC site and see what grades they offer.

My local chemical supplier can supply their "Pharmasolvent" grade which is not true USP although it misleadingly sounds like it is, or they can supply the Gaylord "Industrial" grade, which I have no experience with.

You can buy Pharmasolvent grade that comes from Gaylord on ebay for very low prices. It is the real thing, but it is not USP grade as some of the ads say.

Here are some comments I wrote on another thread (genesis2forum.org/index.php?option=com_kunena&func=view&catid=31&id=6039&Itemid=66#6128):

What you said about the DMSO is probably true, the one that smells a lot is more of an industrial grade. But it probably works just as well. I buy DMSO from my local feed store (FWI Tulsa OK) and have purchased it online and it does not smell much. Gaylord is the company that appears to make much of the DMSO in the US, and possibly throughout the world. They claim on their site to be the only ones making USP (US pharmacopia) grade DMSO under cGMP conditions (www.gaylordchemical.com/products/dmsousp.htm). I don't know if that means they are the only producer of USP grade in the world.

FWI in Tulsa, Oklahoma does apparently produce their own DMSO and they supply it to the veterinary market. I have consumed a lot of theirs and I think it is excellent quality but apparently you cannot get a certificate of analysis from them.

Gaylord sells many grades of DMSO. I talked with the company and the true USP grade costs about 10 times more than the other grades of DMSO available at my chemical supplier. I only know of one site that probably sells true USP grade DMSO (shop.apricotsfromgod.info/DMSO-8-oz-bottle-21.htm) because it is $38 for 8 oz. and that would be more in line with the price the company told me.

Everyone else in the US is selling one of the other Gaylord grades as far as I can tell, unless Jacob labs makes their own somehow. Gaylord has one grade called Pharmasolvent (www.gaylordchemical.com/products/dmsopharmasolvent.php) which looks to me like it would be the cleanest and yet affordable. I bought a drum of this and have a certificate of analysis on it that says it is 99.99% pure. Interestingly it doesn't tastes as good as the FWI at the feed store to my tastes.

My local chemical supplier sells the Pharmasolvent and the Industrial grades of Gaylord, and they are the same price at my supplier. Gaylord's products are available in Europe they told me because I was asking in reference to that, but I imagine they are available throughout the world.

I am only guessing, but I think all the grades of DMSO will work for what we are doing. The cleaner grades are supposed to smell less though, according to the company literature.

Jbnet, if you know of a source of true medical grade DMSO that is not 10 times the cost of the other grades, I would be interested in knowing about it.

More information about the DMSO (Dimethyl Sulfoxide)

Dimethyl Sulfoxide (DMSO) is a highly polar and water miscible organic liquid. It is essentially odorless, and has a low level of toxicity. As do all dipolar aprotic solvents, DMSO has a relatively high boiling point. Gaylord Chemical Company L.L.C. (GCC) is the world’s leading provider of Dimethyl Sulfoxide (DMSO) products.

Since the early 1960’s, the focus of GCC has been on the development of new uses for DMSO. In order to meet customer-specific needs, GCC has pioneered the development of multiple grades of DMSO, including the only DMSO grade that meets USP specifications. The electronics industry values the low-metals grades we produce. Learn more about the grades through the links below.

Available Grades

Procipient® (dimethyl sulfoxide USP, Ph. Eur.): Highly pure grade of DMSO for drug delivery and healthcare applications.

DMSO Anhydrous: An extremely dry grade of DMSO for water sensitive reactions.

DMSO ACS Spectrophotometric: Contains low levels of UV absorbing impurities, for analytical applications.

DMSO ACS Reagent: Grade appropriate for industrial solvent cleaning use.

DMSO PharmaSolvent: The high purity of this product make it solvent of choice for the synthesis of Active Pharmaceutical Ingredients, and intermediates

DMSO EL 10 / DMSO EL 50: DMSO grades with extremely low metals content. Required in electronic applications such photoresist stripping.

DMSO Enviro-S®: An environmentally friendly alternative for sulfiding applications.

DMSO Industrial: A general purpose grade.
