Acetone is a clear, colorless, low-boiling, flammable and volatile liquid characterized by rapid evaporation and a faintly aromatic, sweetish odor. It readily mixes with most organic solvents and mixes completely with water. However, compatibility should be checked prior to mixing with other solvents or materials. Acetone is one of the most widely used industrial solvents. Acetone is low in toxicity. Acetone is extremely flammable with a high vapor pressure; use only with good ventilation and avoid all ignition sources.
