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 that are poorly soluble in water, enhancing drug formulation stability. In cosmetics and personal care products, it functions as a fragrance component and preservative, replacing parabens in some cases. Additionally, it is used in the synthesis of esters for perfumery and flavoring agents. In industrial applications, it acts as a plasticizer and stabilizer in polymer systems.
