Isopropyl Alcohol, commonly referred to as rubbing alcohol, has the chemical formula C3H8O and is a structural isomer of propanol. The most common form of the compound is a clear, colorless liquid that has a very strong odor. The substance is highly flammable both in liquid and vapor form.
The liquid is often used as a solvent and is very good for cleaning lipophilic materials such as oil. It is not highly toxic and is easy to work with, so common cleaning uses include electronic components and lenses as well as screens on everything from computers to cell phones.
Because it dries quickly, it can also be used on tough to clean clothing stains and items such as car parts that cannot have residue left behind. While Isopropyl is not highly toxic, it should be kept out of the reach of children and pets in a cool place to discourage evaporation.
