Acetone: What It Is and Why It's Used

Origin

Acetone is one of the most important industrial solvents and has been produced and used for centuries in various forms. It was identified chemically in the early 19th century. Industrial production initially relied on wood distillation (wood acetone); the Weizmann process, developed in World War I by Chaim Weizmann for acetone production used in cordite explosive manufacture, later gave way to petrochemical synthesis, which now dominates global production.

Why It's Used

In nail polish removers, acetone dissolves the nitrocellulose film-forming polymer in nail lacquer — it is an effective solvent for the lacquer's polymer matrix. It evaporates rapidly and completely, leaving no residue. Acetone-free removers use alternative solvents (typically ethyl acetate or butyl acetate) that are slower and milder but less effective. Both acetone and acetone-free removers are cosmetics; the choice affects efficacy rather than safety at normal use levels.

Elsewhere

Acetone is one of the world's most important industrial solvents, used in the production of plastics (particularly PMMA and polycarbonate via bisphenol A), in pharmaceutical manufacturing, in paint thinning, and in the chemical synthesis of numerous organic compounds. It is also a normal metabolic product in humans.
