Here is a 8 ounce bottle of liquid, 99.99% pure undiluted Sterile Filtered DMSO. This is a PHARMACEUTICAL GRADE SOLVENT and should be used only in a Laboratory. This product is shipped in a container recommended by the manufacturer. The manufacturer recommends that DMSO be stored in polyethylene or polyethylene lined containers (CAS:67-68-5 EINECS: 200-664-3). If you consider transferring the contents into another container, glass is acceptable, but it is subject to breakage and difficult to handle.

Sterile Filtered DMSO is used in many applications, including, but not limited to cell biology, cell freezing, stem cell biology and the treatment of interstitial cystitis. Sterile filtering removes all particles as 1µm, which is as small as cigarette smoke. Sterile filtered DMSO is required by most laboratories and for pharmaceutical penetration enhancement of some drugs. The filtering process is labor intensive and very time consuming.

While it is claimed by some people to be widely used for medicinal purposes, it is not approved by the FDA and prolong or repeated contact may dry skin and cause irritation. It is a great solvent, but care must be used when applying it as it absorbs through the skin into the blood stream, almost instantly. No warranty of fitness for any particular purpose, warranty of merchantability, or any other warranty, either expressed or implied, is made.

Facts About DMSO

1. DMSO is a colorless liquid with a slight solvent odor, similar to garlic.

2. DMSO is readily absorbed through skin, and enhances the rate of skin absorption of skin permeable substances.

3. DMSO is irritating to eyes, respiratory system and skin.

4. DMSO solidifies or freezes at about 68 degrees Fahrenheit.

5. Repeated application of DMSO to the skin results in slight irritation.

6. High vapor concentrations of DMSO may cause drowsiness.



DMSO is a colorless liquid solvent with a slight odor that is similar to garlic. The odor is a characteristic of DMSO and a liquid without that characteristic odor is not pure DMSO. Without the odor it does not have the same chemical makeup commonly and historically known as DMSO. Removing the element causing the odor changes the chemical makeup rendering the liquid to nothing more than a placebo. A liquid without the odor could be anything.

When working with DMSO precautions should be observed. Wear latex or similar gloves. Suntan lotions and insect repellents should be washed off prior to working with DMSO in case of an accidental spill on that area of the skin. Products known to be safe or beneficial to the body, such as Aloe Vera may not have to be removed, unless the area has become dirty.

DMSO will freeze or crystallize at about 68 degrees Fahrenheit (18.4 centigrade) . That usually occurs during shipment, especially during the winter. It will return to liquid form by keeping it at room temperature for several hours. Thawing may be accelerated by placing container in warm water. The freezing and thawing process has no affect on the effectiveness of DMSO. Crystallization temperature will vary from 64 to 68 degrees Fahrenheit between batches. Diluted DMSO will have a lower freeze temperature.
