Isopropyl alcohol (IPA) is a clear, colorless, volatile liquid with a distinct smell. It is also known as isopropanol, 2-propanol or rubbing alcohol. It is widely used as a solvent and as a cleaning fluid, especially for dissolving oils. It is also a widely used ingredient in many pharmaceuticals and personal care products. IPA is highly flammable and can be toxic if ingested. It is typically found in concentrations of 70-99% and is a key component of many household items such as cleaning sprays, paints, and adhesives.
