What is Isopropyl Alcohol?
Isopropyl Alcohol, also known as isopropanol, is a chemical compound commonly used as a solvent and cleaning agent. It is produced by combining water and propylene via a chemical process known as hydration.
In consumer products, isopropyl alcohol is most frequently found in hand sanitizers and hair care products due to its ability to dissolve oils and evaporate quickly, providing an antiseptic effect. The health evidence suggests that it is generally safe when used topically, but it can be irritating to the skin and eyes in high concentrations or with frequent exposure.
When you see it on a label, note that it should only be used externally and kept out of reach of children to avoid accidental ingestion or inhalation.
