Ethyl acetate is a solvent that is used in many industrial processes. It is good at dissolving things, evaporates quickly, and mixes well with other resins and additives. Ethyl acetate EA solvent is very important in making paints, coatings, adhesives, inks and cleaning products.
While it enhances coating performance, understanding its safety hazards and implementing proper handling protocols is critical for protecting workers, the environment, and compliance with global regulations.
This guide breaks down the essential safety considerations for using CAS No 141-78-6 Ethyl Acetate in paints and coatings applications.
What is Ethyl Acetate CAS No.141-78-6?
Ethyl acetate is a versatile organic compound that belongs to the ester family. The chemical formula of this substance is C₄H₈O₂. It is a clear, sweet-smelling liquid that is widely used as a solvent.
Understanding CAS No 141-78-6 Ethyl Acetate: Basic Properties
1. Basic chemical information
It is also called ethyl ethanoate or acetic ester. Its molecular formula is C₄H₈O₂ and its molar mass is 88.11 g/mol. Ethyl acetate is a colourless liquid that has a strong smell of fruit.
2. Core physical and chemical Properties
CAS 141-78-6 Ethyl Acetate boils at 77.2°C and its flash point is -4°C, so it can catch fire easily. The vapor density is 3.04, which is heavier than air, and its vapors easily gather in low places. It dissolves a little in water and can mix fully with common coating organic solvents like alcohols and ketones.

Safety Hazards of Ethyl Acetate in Coatings
Flammability Hazards: Ethyl acetate is extremely flammable; its vapors can form explosive mixtures with air. Never expose it to heat sources, sparks, open flames, or hot surfaces. To avoid the risk of electrostatic discharge, use only non-sparking tools during transfer and ground/connect the container.
Health Hazards: Inhalation of ethyl acetate vapors may cause dizziness, drowsiness, headache, or nausea. Direct skin contact with can cause red, painful, and dry eyes.
Environmental Hazards: Ethyl acetate Solvent is not highly toxic to aquatic life. However, improper handling or spillage into water or soil can cause pollution. EA is also a chemical present in the air we breathe, but high concentrations can contribute to smog. For companies manufacturing coatings, compliance with the U.S. Environmental Protection Agency (EPA) and REACH regulations is crucial, especially when using ethyl acetate with CAS number 141-78-6.
Safe Handling And Storage
Strict rules for operation, storage and personal protection are required to reduce the risks of ethyl acetate. Key operating rules for coating factories are listed below.
1. Handling Guidelines
Operate in fully ventilated spaces. Explosion-proof ventilation devices are preferred to stop vapor build-up.
Prevent direct skin and eye contact. Wear nitrile or neoprene gloves, chemical splash goggles and protective work clothes.
Ground all containers and transfer tools to avoid static electricity.
Keep ethyl acetate away from strong oxidants, strong acids and strong bases.
2. Storage Guidelines
Keep the product in cool, dry and ventilated warehouses. The ambient temperature shall not exceed 30°C. Seal all containers tightly.
Mark all containers clearly with chemical name, CAS 141-78-6 and hazard warning signs.
Use standard containers for flammable liquids, such as stainless steel and HDPE tanks. Do not use large glass containers.
Place fire fighting equipment in storage areas, including alcohol-resistant foam, carbon dioxide and dry powder extinguishers.
