Jan 17, 2024

Dimethyl sulfoxide (DMSO) is a versatile compound with valuable properties, but it also poses potential hazards. Understanding the risks associated with DMSO, implementing safe handling practices, and carefully considering the information provided in the safety data sheet are essential for ensuring the safe purchase, handling, and usage of this compound. 

Delving into the Hazards of Dimethyl Sulfoxide

DMSO poses several hazards that require careful attention:

  1. Toxicity: DMSO is readily absorbed through the skin and can cause systemic toxicity. It can affect the liver, kidneys, and central nervous system, leading to symptoms such as nausea, vomiting, headaches, and dizziness.
  2. Skin Irritation: Contact with DMSO can cause skin irritation, redness, and itching. Prolonged exposure may lead to skin damage and dermatitis.
  3. Eye Damage: DMSO can cause severe eye irritation and potential corneal damage. Contact with the eyes should be avoided.
  4. Flammability: DMSO is flammable and can release flammable vapors when heated. In the presence of an ignition source, such as a spark or open flame, these vapors can ignite, causing a fire or explosion.

Exploring Safe Handling Practices for Dimethyl Sulfoxide

To minimize the risks associated with DMSO, adhere to these safe handling practices:

  1. Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, eye protection, and respiratory protection, when handling DMSO to prevent direct contact with the substance.
  2. Ventilation: Ensure adequate ventilation in areas where DMSO is handled or stored to prevent the buildup of toxic vapors.
  3. Storage: Store DMSO in tightly sealed containers, away from heat sources and incompatible materials.
  4. Disposal: Dispose of DMSO in accordance with local regulations. Never pour DMSO down the drain or into waterways.

Essential Information to Consider When Purchasing Dimethyl Sulfoxide

Before purchasing DMSO, consider the following factors:

  1. Purity: Ensure that you are purchasing DMSO of high purity, as impurities can introduce additional hazards.
  2. Concentration: DMSO is available in various concentrations. Choose the appropriate concentration based on the intended use.
  3. Supplier Reputation: Purchase DMSO from a reputable supplier that can provide safety data sheets (SDS) and information about proper handling and storage.
  4. SDS Review: Carefully read and understand the SDS provided by the supplier. The SDS contains vital information about the hazards, safe handling practices, and emergency measures related to DMSO.
