Dimethyl sulfoxide (DMSO), CAS number 67-68-5, is toxic. Despite this, due to its unique chemical properties, it is classified as a hazardous chemical. As a highly penetrating solvent, it can rapidly transport dissolved toxic components across the skin barrier into the bloodstream. Furthermore, this liquid is classified as a Class 4 flammable liquid, and direct contact with skin and eyes may cause mild irritation.

 

The main safety risks and basic precautions for DMSO 

Skin penetration risk:

This chemical can be rapidly absorbed through skin contact, potentially carrying harmful impurities, leading to stinging, burning, or other unpleasant skin reactions.

 

Irritation risk:

Direct contact can irritate skin tissue and mucous membranes of the eyes, causing localized discomfort.

 

Protective measures:

Operators should wear qualified protective gloves (butyl rubber gloves are recommended over latex gloves) and handle the product in a well-ventilated workplace.

 

Flammability characteristics:

DMSO is a flammable liquid with a flash point of 192°F (90°C).

 

Toxicological characteristics:

Under normal exposure conditions, DMSO has low acute toxicity. However, high-dose exposure or accidental ingestion may cause adverse reactions such as nausea, vomiting, and central nervous system disorders.
