Industrial Applications of Dimethyl Sulfoxide:
- Paint Stripping Applications: Dimethyl Sulfoxide DMSO is a non-toxic and biodegradable solvent that serves as an alternative to the hazardous polar solvents typically used in conventional paint strippers. DMSO demonstrates exceptional stripping performance across a wide range of coatings, including enamels, elastomers, latex paints, polyurethanes, and various cured polyurethane systems.
- Polymer Cleaning: DMSO (CAS 67-68-5) is a powerful polymer cleaning solvent. Compared to commonly used cleaning solvents such as acetone, DMSO offers significant advantages, notably being non-flammable and exhibiting low volatility.
Pharmaceutical Uses of DMSO:
- DMSO plays a significant role in the pharmaceutical industry:
- It serves as a drug delivery enhancer.
- dimethyl sulfoxide is utilized in pharmaceutical formulations.
- It is applied in treatments for inflammation and pain relief (to be used under medical supervision).
Safety and Handling Information
DMSO has a special property of enhancing skin penetration. It can carry dissolved substances through the skin, which requires careful handling in industrial environments.
Recommended precautions:
- Wear chemical-resistant gloves (nitrile gloves recommended)
- Use protective goggles and suitable PPE
- Avoid skin contact with contaminated DMSO solutions
- Store away from incompatible chemicals
- Handle in a well-ventilated area
- Always refer to the SDS before use.
Storage Conditions
DMSO has a melting point of approximately 18.4°C.
Recommended storage conditions:
- Store at 20–25°C
- Keep container tightly sealed
- Store in a cool, dry, and well-ventilated area
- Avoid prolonged storage below 18°C
If DMSO freezes during transportation or storage, warm gradually to room temperature until completely liquefied. Freezing does not affect product quality when handled properly.
