Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils.
Isopropyl alcohol is known as ârubbingâ alcohol because it can be used to rub glue, grease, and paint off dirty surfaces. Rubbing alcohol dissolves fats. It also dissolves DNA, and is used in testing labs to remove the DNA from tissue samples for genetic analysis. Rubbing alcohol dissolves DNA of bacteria and human skin cells. 2  Since rubbing alcohol kills skin cells in the lining of pores, it can cause them to become clogged with dead skin. 3  Rubbing alcohol usually creates new blemishes rather than eliminating old ones.
