The common name for acetone, a colorless, volatile liquid (CH₃COCH₃) with a ketone functional group and two methyl groups, widely used as a solvent and nail polish remover.
From dimethyl (two methyl groups) + ketone (from German Keton). Acetone itself derives from acetic acid. Dimethylketone is the systematic way to describe acetone's chemical structure.
Acetone (dimethylketone) evaporates so quickly that it cools your skin—which is why it feels cold when you use nail polish remover, and why it's perfect for dissolving greasy stains.
