Is ethyl acetate toxic to humans?

Dec 11, 2025 Leave a message

When used correctly in industrial settings, ethyl acetate (CAS 141-78-6) is considered a low-toxicity solvent. However, short-term exposure to high concentrations of its vapors may trigger dizziness, eye irritation, headaches, and respiratory discomfort.

 

What is Ethyl acetate cAS 141-78-6 solvent?

CAS 141-78-6 Ethyl acetate is a colorless transparent liquid with low toxicity, a sweet taste, and a pungent odor at high concentrations. It is volatile, sensitive to air, and can absorb water, causing it to slowly hydrolyze and undergo an acidic reaction. Can be miscible with chloroform, ethanol, acetone, and ether, soluble in water. Due to its rapid evaporation rate and strong solubility, ethyl acetate solvent is widely used in many industries. Its application areas include coatings and paints, printing inks, adhesives, pharmaceuticals, fragrance and flavor production, nail polish removers, chemical intermediates, and industrial cleaning agents.

 

Is ethyl acetate toxic to humans?

Yes, ethyl acetate is considered hazardous and can be toxic to humans, especially at high concentrations or with prolonged exposure.

 

Hazards:

Ethyl acetate can cause irritation to the eyes, skin, and respiratory system. Inhalation of high concentrations can lead to central nervous system depression, dizziness, and headache.

 

Handling: Should be handled with proper protective equipment, including gloves, goggles, and protective clothing. Ensure good ventilation or use in a fume hood to avoid inhalation of vapors.

 

Storage: Store in a cool, dry place away from sources of ignition and incompatible materials like strong acids or bases. Containers should be kept tightly closed to prevent evaporation and contamination.
