The question of purity of DMSO has surfaced multiple times (on this list) over the past seven years.....the pertinent parameters remain the same. A majority of DMSO produced in the USA originates with about three companies, the largest producer remains James River Paper Co. (formerly Crown Zellerbach)...or at least our purchasing agent informs me. As DMSO is produced, primarily, as a universal-type chemical solvent....the commercial market for medical applications remains a microscopic one (in terms of total dollars). The purity question hardly (it seems to me) demands intense examination....as the only concern of high order would appear to be one of contamination through negligent bottling/packaging techniques. (The bulk DMSO product is routinely and regularly verified by U.S. Government Chemical Process Inspectors.) While conceivable in nature, such infrequent potential aberrations do not readily recommend a major concern. At least they never have with us. Early on (circa 1992)in our evaluations of DMSO purity (at the beginning of our personal human experimentations....primarily topical in character), we did conduct contamination analyses on separate purchases from different wholesale...and retail...vendors. After 50 or so series of tests we discontinued the practice. It is conceivable that the plastic vessels containing a majority of the product sold to the general public, might reveal some out-gassing from the container material....but we have never found such evidence. While there are sellers of DMSO material touted as "Medical Grade", we have been unable to detect ANY differences (except the glass container), whatsoever, between the product sold by the local Agricultural Feed Store and that offered by Medical Supply houses at a price increase of an order of magnitude. In closing I would like to add that due to the EXTREMELY powerful solvent, entraining and transport capabilities of DMSO....maintaining rational precautions regarding what---and how---companion substances are incorporated recommends good judgement.
