What is DMSO?
Dimethyl sulfoxide (DMSO) is an organic solvent that can be derived naturally from wood. It has a slightly oily consistency and in its pure state is practically odourless. DMSO is hygroscopic (binds water).
The melting point of DMSO is 18°C, and under this temperature DMSO will crystallise. In Switzerland, DMSO, in combination with other ingredients, is allowed to be sold as a drug.
DMSO vs MSM
The suphur-containing compound MSM is closely related to DMSO and both substances are chemically similar, but they differ in their effects.
The body metabolises DMSO into dimethyl sulfide (DMS) and dimethyl sulfone (DMSO2):
- The sulphureous DMS is expelled via the lungs as well as through the skin.
- DMSO2 corresponds to the organic substance MSM (methylsulfonylmethane), which is a known food supplement
Solubility and Crystallisation
DMSO crystallises at temperatures under 18°C. This process is reversible, and from temperatures of 20-22°C, the DMSO becomes fluid again. To liquify the DMSO, place the glass bottle in warm (not hot) water. Do not place in the microwave, as this destroys the structure of the DMSO.
Our DMSO meets the standards of the Ph. Eur. (European Pharmacopoeia) 8.8. of 2017.
