Acetone
What is Acetone?
Acetone is a simple ketone, a colorless, highly volatile liquid with a distinctive odor, produced synthetically or via natural fermentation processes. In cosmetics, it belongs to the solvent category, commonly found in nail care items like removers and hardeners, as well as some cleansers and toners. It functions by effectively dissolving oils, resins, and other non-water-soluble substances, enabling the creation of clear formulations. Its rapid evaporation leaves no residue, aiding in fast-drying products. Acetone also denatures alcohol to make it unfit for consumption, a regulatory requirement in certain sprays and fragrances. While versatile for formulation control, its strong solvency can strip skin lipids if overused.
