It is a topically applied component used in cosmetics, scents, and pharmaceutical preparations (such rubbing compounds, lotions, tonics, and colognes) to prevent skin infections. As Proof alcohol is used in industry as a solvent for fats, oils, waxes, resins, and hydrocarbons, fuels that are designated as "ethanol-blended fuels" may contain alcohol.
