Things worth knowing about "Ethyl acetate"
Ethyl acetate is an organic solvent with a fruity odour, widely used in food, cosmetics, pharmaceuticals, and industrial applications.
What is Ethyl Acetate?
Ethyl acetate (also known as ethyl ethanoate or acetic acid ethyl ester) is an organic ester formed by the reaction of ethanol with acetic acid. It is a colourless, volatile liquid with a characteristic sweet, fruity smell reminiscent of fruit candy or nail polish remover. Its chemical formula is C₄H₈O₂ (CH₃COOC₂H₅).
Occurrence and Uses
Ethyl acetate occurs naturally in many foods, including wine, beer, fruits, and fermented products. It has a wide range of industrial applications:
- Food industry: Used as a flavouring agent (e.g. fruit flavour) and solvent for food additives; approved in the EU as food additive E1504.
- Cosmetics and pharmaceuticals: Used as a solvent in nail polishes, perfumes, and pharmaceutical preparations.
- Industry and technology: Widely used as a solvent for lacquers, adhesives, printing inks, and cleaning agents.
- Coffee decaffeination: Employed as a natural solvent to extract caffeine from coffee beans.
- Analytical chemistry: Frequently used as a solvent in thin-layer chromatography and other laboratory techniques.
Effects on the Human Body
Ethyl acetate is considered relatively low in toxicity when used as intended and in small quantities. However, several health-related aspects are relevant:
Acute Effects
- Inhalation of high concentrations can cause irritation of the eyes, nose, throat, and respiratory tract.
- At very high concentrations, dizziness, headaches, fatigue, and impaired consciousness may occur due to its narcotic properties.
- Skin contact can lead to dryness and mild irritation, as ethyl acetate has a defatting effect on skin.
Chronic Effects
- Long-term occupational exposure to high concentrations may cause damage to the liver and kidneys.
- Repeated skin contact can lead to dermatitis (skin inflammation).
Safety and Exposure Limits
Ethyl acetate is flammable and can form explosive mixtures with air. Occupational exposure limits apply in most countries (e.g. the maximum workplace concentration in Germany is 400 ppm). The European Food Safety Authority (EFSA) has assessed ethyl acetate as a food flavouring substance and considered it safe at concentrations typically used in food production. In the body, ethyl acetate is rapidly broken down by esterases into ethanol and acetic acid and subsequently metabolised.
Ethyl Acetate in Fermented Beverages
In wine and beer, ethyl acetate is produced as a natural by-product of alcoholic fermentation. In excessive concentrations, it is perceived as a wine fault and gives the beverage an unpleasant, solvent-like off-flavour. The sensory detection threshold in wine is approximately 120–160 mg/l.
