Our DMSO is 99.9% pure, whether it's in our liquid Gallons/Pints, or in our gels, like our 8 oz Roll-on. By volume, our gels are 90% DMSO (at 99.9% purity) and 10% gel.

Our gels are made with Carbopol, which is a common, widely used water-soluble polymer. It's used in an array of industries as an emulsifying, stabilizing, and suspending material for things like shampoo, hand sanitizer, lotion, and bath gel.

Because DMSO is a strong solvent, only a few polymer materials can be used under continuous exposure. Of the seven forms of plastics, we use BPA-free, high-density polyethylene (HDPE) and/or polypropylene (PP) containers and lids. We were the first company to package DMSO for sale in the United States. We’ve used these same materials for over 45 years and they’re 100% compatible with DMSO. There are also numerous compatibility charts available to the public, most of which are available online if you’d like to research further. 

We avoid glass containers due to safety and chips/breakage issues involved in shipping.

Yes. BPA is not used in the manufacturing process of our bottles or caps/lids.

Crystallization is normal for DMSO, especially during cold weather, and it does not affect the efficacy or purity of the product after thawing occurs.

The melting point/freezing point for pure DMSO liquid is 65.3°F. Products can become crystallized (hard/frozen) when the product has been stored in temperatures 65.3°F and/or below. This can occur during shipping.

For constant liquidity, storage is recommended at approximately 70°F or higher.

To accelerate the thawing process, you can place the sealed DMSO container in a warm water bath. Never microwave.

The product will then thaw and return to its original liquid or gel form and can be used as normal.

When stored properly, our DMSO liquids and gels expire after approximately 5 years.

Originally, DMSO was made from wood pulp (from different trees depending on the location or the producer), however that's no longer the case for most producers today.

With current technology, the process to produce DMSO is more reliable, cleaner, and creates higher purity DMSO than those made as a byproduct of the Kraft (wood pulp) process.

The Kraft process for making DMSO required the byproducts of wood pulp production, but those byproducts were then further reacted in the manufacturing of DMSO. Nowadays, the manufacturing process no longer depends on the paper-wood pulp making process for obtaining the raw materials needed to make DMSO.

DMSO is supported by over 50 years of industrial and academic experience. Many prominent researchers have studied DMSO over the years.

If you would like to do more research on DMSO “The DMSO Handbook” by Hartmut Fischer “DMSO Nature’s Healer” by Dr. Morton Walter, as well as publications from Dr. Stanley Jacob and Dr Joseph Mercola are all great resources.
