Isopropyl Alcohol, also known as rubbing alcohol, is a clear, colorless liquid with a strong odor. It has a molecular formula of C3H8O and is soluble in water. Isopropyl Alcohol is commonly used in cosmetic products such as aftershaves, toners, and antiperspirants for its ability to kill bacteria and act as a solvent. It is also used as a degreaser and astringent in industrial settings. Isopropyl Alcohol evaporates quickly and leaves behind no residue, making it a popular choice for cleaning and disinfecting. While it can be drying to the skin, it is generally considered safe for topical use in low concentrations.
Origin
Isopropyl alcohol is produced by the direct hydration of propylene with water, which forms isopropyl alcohol and a small amount of diisopropyl ether. Alternatively, it can be synthesized through the hydrogenation of acetone, a byproduct of the cumene process.
Safety profile
Isopropyl alcohol is generally safe for use in cosmetics and personal care products when used in appropriate concentrations. However, it can be drying and irritating to the skin in high concentrations. It is important to note that its use should be avoided in open wounds or damaged skin. Patch testing is recommended before use on sensitive skin. Isopropyl alcohol is also considered vegan and halal.
