Isopropyl alcohol, also known as rubbing alcohol, is known to be drying/sensitizing to skin when listed among the main ingredients (higher up on the ingredient list); tiny amounts in an otherwise good formula aren’t a problem. In addition to being drying and sensitizing, this type of alcohol can disrupt skin’s surface layers.

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.
