ACETONE
Safety grade: C**
Acetone is a colorless, fast-evaporating liquid commonly found in nail polish removers and paint thinners. In cosmetics, it helps dissolve and mix other ingredients together while evaporating quickly from the product.
Acetone acts as a solvent to help dissolve and blend ingredients, and as a denaturant to make ethanol unsuitable for consumption in cosmetic formulations.
