Interesting idea Matthew. But I feel that if it was this easy, well someone would have already been producing odorless DMSO this way.
You might be interested in the information Gaylord Chemical has about the impurity that they remove to make their odorless USP DMSO. http://www.gaylordchemical.com/home/default.asp "Gaylord Chemical provides the only USP grade DMSO backed by a Drug Master File [link to pdf] . . . A little known fact is that an impurity BMTM (bis-(methylthio)methane) is responsible for most of the odor . . . Gaylord Chemical has developed engineering processes that remove this and all other odor causing trace impurities from USP grade DMSO." Their product is $180 / liter or $100 / 500 ml. Producing a USP product requires a very expensive set up. www.jacoblab.com has a low odor product made by adding 10% urea. It is not USP. I have not tried either product, both are pricey. To obtain Gaylord's USP DMSO you must be a health care practitioner. Their vendors will not sell to the public according to the VP of Marketing that I spoke to a few months ago. For now I will put up with the odor as I pay ~$5 for 16 oz from www.jeffersequine.com -- but I would like to try it when I have time to track down a vendor and can afford the high price tag. If I were taking it orally or using real often good manners would dictate that I spring for the higher priced product. My family dislikes the smell very much, but they do try not to complain since it is so effective for the uses we do find for it. Some of the odor is supposedly due to metabolites of DMSO, specifically Dimethyl Sulfide. A garlicky smelling compound found in many foods like coffee, corn, oysters and others. If this is true then the Gaylord product should still produce some odor.
