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, preservative, and viscosity reducer. Additionally, it is employed in the synthesis of esters used in perfumery and as a local anesthetic in some medical applications. Its low toxicity and ability to enhance penetration make it valuable in topical formulations.
