Benzyl alcohol is widely used as a preservative in the pharmaceutical and cosmetic industries. It can effectively inhibit the growth of bacteria and mold, thereby extending the shelf life of the product.
At a concentration of 0.5% to 1%, benzyl alcohol exhibits a significant preservative effect and is often used in injections and ophthalmic drugs.
