What Are the Chemical Properties of Acetone?
Acetone’s chemical structure denotes that it is composed of three elements: carbon, hydrogen, and oxygen. It is colorless, emits a pungent scent, and is volatile and flammable. Acetone’s boiling point is 56°C (133°F), making it water-soluble and easy to mix with different solutions. This organic solvent is capable of dissolving numerous chemicals, which makes it ideal for cleaning and manufacturing. Furthermore, acetone’s ability to quickly evaporate enables the quick-drying of products.
Is Acetone a Ketone?
Acetone is a recognized ketone and also one of the simplest and common ketones in existence. The carbonyl group’s (C=O) bond with methyl groups (CH₃) constitutes acetones characteristic features. Thus, acetone or propan-2-one are aliphatic ketones due to having an open-chain structure.
Acetone can be found in specific parts of nature which includes the metabolism of certain animals and certain plants. For example, during the breakdown of fats, the human body tends to produce small quantities of acetone, especially during prolonged fasting periods or while following a ketogenic diet. In those circumstances, acetone levels can be 0.5 to 5 mg/dL in blood and 1–2 mg/dL in urine.
In terms of industry, acetone is a very important product for manufactured goods. In 2022, production of acetone reached approximately 7 million metric tons. This was primarily brought on by the pharmaceutical market, plastic industry, and the personal care market. It is used as a precursor in the synthesis of methyl methacrylate (MMA) and bisphenol A (BPA) which are essential to producing acrylic plastics and epoxy resins. Also, due to the properties of acetone, it is used in nail polish remover, some adhesives, and as a reagent in some laboratories.
Because acetone is flammable, delicate and stringent safety protocols must be followed when handling or disposing of it. Acetone is considered a volatile organic compound (VOC) and in many places, it is under environmental regulations to protect the air from pollution.
Why Is Acetone Considered a Volatile Organic Compound?
Acetone is considered a volatile organic compound as it can evaporate at room temperature, releasing organic substances into the environment. In addition, the boiling point of acetone is about 56 degrees centigrade or 132.8 degrees Fahrenheit, making the change for liquid to gas easier and faster. It is known that VOCs such as acetone can affect the quality of air; also, the VOC emissions have been a point of concern owing to their tendency to contribute to ground-level ozone and secondary organic aerosols, which are detrimental to human health and the environment.
The U.S Environmental Protection Agency (EPA) concerns VOC emissions and suggests there needs to be control in processes such as manufacturing of products and industry to reduce the emission of air pollutant. Studies indicate that indoor air concentrations of acetone might range from 1 to 1150 ug per cm cubed depending on ventilation and products used. In addition, the high flammability of acetone poses great risks when transporting and storing the compound. Even with the challenges, it is labeled as low concern when compared to other VOCs, as it is less toxic and breaks down faster in the atmosphere.

Moreover, acetone can also serve as a cleaning agent for nails and cosmetic tools because of its ability to cut grease.
Why Is Acetone Used In Nail Polish Removers?
Acetone serves as an active ingredient in various forms of nail polish remover. It breaks down the polymers and resins used in the nail polish, and as a strong solvent, ensures that it is removed with ease. Studies show that acetone has a boiling point of 56 degrees Celsius (132.8 degrees Fahrenheit), making it volatile. This property allows acetone to evaporate quickly without leaving any residue which makes it perfect for removing nail polish without stains.
Moreover, information from cosmetic uses suggests that acetone may be safely utilized in well-ventilated settings and in small quantities. It does have low acute toxicity, however, its skin drying or irritating effects may occur with prolonged exposure. This is the reason why many polish removers now contain moisturizing ingredients like glycerin or aloe vera—so that the drying effects of acetone can be counterbalanced. Such formulations are effective in removing polish while minimizing harmful effects on the skin.
Why Is Acetone A Good Solvent For Nail Polish
Because of its unique properties, acetone is an outstanding nail polish remover. Its dissolving power on organic compounds such as nitrocellulose and the plasticizers used in nail polish is due to its polarity and low molecular weight. Newer data indicates that the dielectric constant of acetone is 20.7. This means it is sufficiently polar to dissolve substances bound by polar bonds. Thus, it can also be used to gain access to coatings and rapidly decompose the polish into easily removable constituents.
Additionally, acetone’s strong volatility leads to quick drying and moisture leaving only a small residue on the nails. Environmental data indicates that acetone’s boiling point is 56 degrees centigrade (or 132.8 degrees Fahrenheit). Thus, it can be used for very fast drying purposes. Studies show that stubborn glitter or glue based polishes which other solutions take ages to polish off, acetone works within seconds. This effect decreases the amount of time needed for application which reduces exposure time to the skin and nails.
Between saftey and effectiveness, acetone remains the most reliable and widely used solvent in cosmetic industry for nail polish remover because of the fast action and effectiveness when applied.
How Is the Production of Acetone Carried Out?
The cumene process is the industrial method most frequently used for synthesizing acetone. It consists of the oxidation of isopropylbenzene (cumene) to yield acetone and phenol. The cumene process remains unrivaled in its coverage in the industrial market for acetone because it is cost-effective and provides high-grade acetone.
What Processes Are Used to Produce Acetone?
The cumene method is responsible for approximately 90 percent of acetone production worldwide. There are three core stages of this method: alkylation, oxidation, and acid-catalyzed cleavage. First, benzene undergoes alkylation with propylene to yield cumene (isopropylbenzene). Air oxidation of cumene to cumene hydroperoxide follows. The last step involves acid-catalyzed cleavage of the hydroperoxide to yield acetone and phenol.
Other ways of producing acetone are fermentation with some bacteria, dehydrogenation of isopropanol, and, dehydrogenation of isopropanol which tends to be more useful when produced on a smaller scale. Fermentation, unlike the other processes, results in lower yield as a result of the processes, for example, with Clostridium acetobutylicum using carbohydrates as an energy source. Dehydrogenation of isopropanol demonstrates a simpler and less expensive way of production.
Acetone production surpassed 7 million metric tons in 2022, with its use in plastic, solvent, and personal care manufacturing being the primary demand driver. Afterward, the Asia-Pacific region continued leading both in production and consumption, having over 40% market share.

Also, higher exposure levels of acetone for a short duration can lead to eye, nose and throat irritation, headaches, and nausea among other symptoms.
Lower acetone exposure over a prolonged period may still result in adverse effects such as damage to the central nervous system, liver, and kidneys. The CDC notes that children and certain pre-existing conditions can make one susceptible. In environments where acetone is necessary, good ventilation must be provided, and PPE such as gloves and respirators must be worn to minimize health risks.
To maintain workplace safety where acetone is used, environmental monitoring and regular health checks are advised. For nail polish remover acetone users, avoiding prolonged exposure, while ensuring appropriate ventilation during use is important.
What is the safest way to store acetone?
Due to acetone’s flamability and volatility, it must be stored with great care. This chemical should only be kept in specially designated containers for flammable substances such as steel and certain plastics. These need to be marked clearly to prevent mix-ups. OSHA (Occupational Safety and Health Administration) recommends that these containers be stored in cool, dry, and well- ventilated places below 20°C to minimize evaporation.
In addition, acetone must be kept away from open flames or any form of electrical equipment since those can cause sparks. The NFPA (National Fire Protection Association) classifies acetone as a Class IB flammable liquid which means it can ignite very easily. About 65% of the accidents involving acetone in industrial workplaces occur due to poor storage practices or exposure to heat sources. To reduce risks, facilities that store acetone should incorporate fire suppression systems and adhere to local fire codes.
For acetone storage at home, containers should be kept out of reach from children and pets. Users must ensure that the cabinets where the containers are kept are ventilated and lockable.
