Alcohol
Alcohol, also known as ethanol (CAS #64-17-5), is a widely used cosmetic ingredient that functions as a solvent, penetration enhancer, astringent, and antimicrobial agent. It is commonly found in toners and formulas targeting oily skin due to its ability to create light, cosmetically elegant textures. It is a controversial ingredient with both notable benefits and potential drawbacks depending on its concentration and position in a formula.
Alcohol acts as an effective solvent and penetration enhancer, helps create lightweight formulas, and provides astringent and antimicrobial properties. It is particularly popular in toners and oily skin products for its ability to reduce surface oiliness and deliver a clean, non-greasy finish.
Can be very drying when listed among the first few ingredients on a product's ingredient list. Some experts suggest that regular exposure may damage the skin barrier and cause inflammation, though this remains a debated opinion.
