Is DMSO safe for human use?

Oct 29, 2025 Leave a message

The CAS number 67-68-5 is for dimethyl sulfoxide (DMSO). Dimethyl sulfoxide is a sulfur-containing organic compound with the molecular formula C₂H₂OS. It is a colorless, odorless, transparent liquid at room temperature and is hygroscopic and flammable. CAS 67-68-5 is highly polar, has a high boiling point, is thermally stable, is aprotic, and is miscible with water. It is soluble in most organic compounds, including ethanol, propanol, benzene, and chloroform, earning it the nickname "universal solvent."

 

DMSO is approved for human use as a prescription treatment for certain conditions (like interstitial cystitis) and is used in clinical settings.

Pharmaceutical-grade DMSO is generally considered safe for topical use in approved medical products (e.g., for pain relief), though it may cause mild skin irritation (e.g., redness, a "garlic-like" taste) in some individuals. However, industrial-grade DMSO (containing impurities like dimethyl sulfide or heavy metals) is unsafe for human contact
