Alcohol

Ethanol (ethyl alcohol) is a volatile, colorless alcohol obtained through fermentation of plant sugars, commonly from sugarcane, corn, or wheat. In cosmetic formulations, it serves as a powerful solvent that dissolves both water-soluble and oil-soluble ingredients, while also providing antimicrobial properties and creating a light, fast-absorbing skin feel. Formulators value it for its ability to reduce greasiness, enhance ingredient penetration, and provide a cooling sensation upon application, though its drying effect requires careful balancing in leave-on products.
