Acetone is a colorless, flammable liquid that evaporates easily. It is an organic compound because the carbon atoms are present in the chemical formula of acetone, which is (CH3)2O. It consists of three carbon atoms, six hydrogen atoms and one oxygen atom.

Acetone belongs to the class of ketones, which are organic compounds containing a carbonyl group bonded to two hydrocarbon groups. Acetone has a carbonyl group in which carbon and oxygen are bonded to each other through a double bond and is known as the simplest ketone.
Acetone is a solvent, a liquid that can dissolve other substances. Acetone is most commonly known as a solvent for removing nail polish, but it's also found in bath and fragrance products, hair and skin care products, and whitening products.

When you come into contact with a nail polish remover that contains acetone, you may notice that your skin becomes very dry. Acetone is volatile. In other words, it evaporates quickly. Dermatologists take advantage of this drying effect when patients come in for chemical peels; before exfoliation, the skin is first cleaned with acetone and removes excess fat and oil in a process called defatting.

Have you ever had a thing with superglue? If it gets on your hands, it may take a few days to remove it from your skin. Superglue can be removed very quickly if acetone is used. Acetone can also remove stains from permanent markers and epoxies before they harden. In the kitchen, we wash dishes with water. In a chemistry lab, wash dishes with acetone to remove traces of moisture, so glassware dries out quickly.

Acetone is used as a solvent for various substances due to its ability to mix with most organic solvents and water. For example, it is a solvent for flammable or volatile substances such as acetylene, allowing safe transport and storage of these substances. Acetone is also a useful solvent in the pharmaceutical industry; used as a chemical intermediate and as a solvent for vitamins and cosmetics.
Acetone is a clear, colorless liquid with a sweet smell. Flash point 0°F. Density is less than water. Vapor is heavier than air. Used as a solvent in paint and nail polish removers.
Acetone is a colorless, volatile, flammable organic solvent. Acetone occurs naturally in plants, trees, forest fires, automobile exhaust, and is a breakdown product of animal fat metabolism. This substance may usually be present in urine and blood in very small amounts; more may be found in the urine and blood of people with diabetes. Acetone is toxic in high doses.
Acetone is a man-made chemical that also occurs naturally in the environment. It is a colorless liquid with a distinctive smell and taste. Volatile, flammable, soluble in water. It is also known as dimethyl ketone, 2-propanone, and beta-ketopropane. Acetone is used to make plastics, fibers, pharmaceuticals, and other chemicals. It is also used to dissolve other substances. It occurs naturally in plants, trees, volcanic gases, forest fires, and is a product of the breakdown of fat in the body. It's found in car exhaust, tobacco smoke, and landfills. Industrial processes contribute more acetone to the environment than natural processes.
