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 (to create the gel). Carbopol 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.

The melting point/freezing point for pure DMSO liquid is 65.3°F (18.5°C).  Products can become crystallized (hard/frozen) when the product has been stored in temperatures 65.3°F (18.5 °C) and/or below.  For constant liquidity, storage is recommended at approximately 70°F (21°C) or higher. Product may crystalize during transit. To accelerate the thawing process, place the sealed DMSO container in a warm water bath. Never microwave. Crystallization does not affect the efficacy or purity of the product after thawing occurs.

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

We only use the safest processing equipment and product containers available based on DMSO’s physical properties and good manufacturing practice. 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 high-density polyethylene (HDPE) and/or polypropylene (PP) containers and lids.  We’ve used these same materials for over 45 years and they’re 100% compatible with DMSO.

DMSO is a commercially manufactured nontoxic organic solvent or cosolvent; however, it is also a naturally occurring substance in a variety of foods and beverages. It is supported by over 50 years of industrial and academic experience. To determine the safety of this chemical, there have been numerous toxicological, environmental, and medical studies over the decades. Many prominent researchers have studied DMSO over the years such as Dr. Stanley Jacob (known as the "Father of DMSO") and Dr Joseph Mercola.
