Used as a preservative in injectable medications due to its antimicrobial properties, benzyl alcohol prevents bacterial growth in multi-dose drug formulations. It also serves as a solvent for active pharmaceutical ingredients that are poorly soluble in water. In cosmetics and skincare products, it functions as a fragrance component and mild preservative. Additionally, it is used in the synthesis of esters for perfumery and as a local anesthetic in some topical formulations. Industrial applications include use as a plasticizer and in dye formulations.
