Widely used as a preservative in injectable medications due to its antimicrobial properties, benzyl alcohol prevents bacterial growth in multi-dose vials. It also serves as a solvent for active pharmaceutical ingredients, enhancing drug stability and solubility. In cosmetics and skincare products, it functions as a fragrance component and mild preservative; while generally suitable, it may cause irritation in individuals with sensitive skin at higher concentrations. Additionally, it is employed in the synthesis of esters used in flavor and fragrance formulations. In industrial applications, it acts as a plasticizer and stabilizer in polymer systems, and is used in paints, inks, and cleaning products.
