Nail polish remover is made from acetone. This is an organic solvent. It's formula is (CH3)2CO. It is a colorless, mobile, flammable liquid which is a ketone. This is an organic compound with the structure RC(=O)R' where R and R' can be a variety of carbon containing substituents. Commercially, acetone is produced from propylene. Benzene is alkylated with propylene to produce cumene. This is then oxidized in air to produce both phenol and acetone. Approximately 6.7 million tonnes were produced in 2010 used as a solvent. The body also produces its own acetone by the decarboxylation of ketone bodies. This is called biosynthesis. The body produces and disposes of it as a normal metabolic process. It is found in blood and urine.
