Is ethyl acetate a solvent (CAS 141 78 6)?

CAS 141-78-6 Ethyl acetate is a very common and versatile organic solvent.

Ethyl acetate (EtOAc) is a clear, colourless liquid with a pleasant fruity smell reminiscent of ripe pears. Boasting key properties that make it indispensable across industries, it features a boiling point of 77.1°C, a melting point of -83.6°C, and high volatility-enabling rapid evaporation that is critical for time-sensitive processes. It exhibits excellent solubility in organic solvents such as ethanol, ether, and acetone, while being slightly miscible in water, paired with a flash point of -4°C (closed cup) that classifies it as a flammable liquid requiring standard safety precautions.

These inherent characteristics make ethyl acetate (CAS 141 78 6) a versatile workhorse:

It is widely utilized as a solvent in the coatings, paints, adhesives, and printing ink industries, where its fast-drying nature and strong solvency power enhance product performance and production efficiency. Additionally, its mild, fruity aroma and low toxicity qualify it as a safe flavouring agent in the food industry, used to mimic natural fruit notes in confectionery, beverages, and baked goods. As a prominent ester, ethyl acetate stands as one of the most important chemical compounds supporting a diverse range of industrial processes worldwide.

Is ethyl acetate a toxic solvent?

Ethyl acetate is generally considered a low-toxicity solvent relative to many alternative.

Its primary hazards are:

• Flammability (its most significant risk).
• Irritant: It can cause irritation to the eyes, respiratory tract, and skin upon exposure.
• Narcotic Effects: High vapor concentrations can cause dizziness, drowsiness, and central nervous system depression.

Its "low toxicity" refers to its lack of severe long-term health effects when exposure is controlled, but proper ventilation and personal protective equipment (PPE) are always required.
