Product Usage
Benzyl alcohol is the simplest aromatic alcohol and is widely used across multiple industries. In the pharmaceutical field, it is mainly used as an excipient in local anesthetics and as a preservative in injections, effectively inhibiting microbial growth. In the cosmetics and personal care industry, it serves as a fixative and solvent, commonly found in perfumes, skin care products, and shampoos. In the coatings and ink industry, benzyl alcohol is an effective coalescing agent and leveling agent, improving coating uniformity. Additionally, it is used as a cleaning agent in electronic chemicals and as a flavoring ingredient in the food industry. Its low toxicity and good solubility make it an important fine chemical intermediate.
