What Is Benzyl Benzoate?
Benzyl benzoate (C14H12O2) is an ester of benzyl alcohol and benzoic acid, found naturally in some balsams and used extensively in medical and industrial applications. Classified for safe use as a flavoring agent, it’s also recognized for its pharmaceutical and insecticidal properties.
Uses of Benzyl Benzoate
Medically, it’s employed for its vasodilating effects and as a treatment for scabies and lice. Its insecticidal qualities make it effective against ticks and mosquitoes. Industrially, it’s used as a flavoring agent, a preservative in foods, a plasticizer for polymers, and a solvent in perfumes.
