Application
Benzyl benzoate is a versatile ester with a wide range of applications across pharmaceutical, cosmetic, and industrial sectors. In the pharmaceutical industry, it is most notably used as an active ingredient in topical preparations for the treatment of scabies and pediculosis (head and body lice), often formulated as a 10 to 25 percent emulsion or lotion. It is also employed as a solvent for intramuscular injections, particularly for certain hormonal preparations, due to its low toxicity and good solubilizing power. In the flavor and fragrance industry, benzyl benzoate serves as a valuable fixative and solvent for essential oils, imparting sweet, balsamic notes to perfumes, soaps, detergents, and personal care products. It is widely used in jasmine, tuberose, and gardenia accords. As a plasticizer, it is used with cellulose esters (e.g., cellulose acetate, nitrocellulose) to improve flexibility and processing in coatings, inks, and adhesives. It also functions as a solvent in the production of synthetic resins and as a dye carrier for polyester textiles. In the food industry, benzyl benzoate is permitted as a flavoring agent and adjuvant (FEMA 2138) in baked goods, confectionery, and beverages. Additionally, it is used as a solvent for pesticides and as an acaricide in beekeeping to control Varroa mites. In organic synthesis, it serves as an esterification reagent and as a precursor to benzoic acid and benzyl alcohol derivatives. Its low volatility and high boiling point make it a preferred solvent for high temperature reactions.

FAQ
Q1 How should benzyl benzoate be stored to maintain its quality?
A Store in a cool, dry, well ventilated area away from strong oxidizers and acids. Keep container tightly sealed. If solidified, warm gently to 25 to 30 deg C to liquefy before use. Shelf life is 36 months under recommended conditions.
Q2 What purity grades do you supply?
A Standard grade is 99.0 percent by GC. We also supply 99.5 percent grade for pharmaceutical injectable applications and 99.8 percent grade for analytical reference standards.
Q3 Is benzyl benzoate soluble in water?
A It is practically insoluble in water. It is miscible with alcohol, ether, chloroform, fixed oils, and most organic solvents.
Q4 Do you provide sample quantities for formulation development?
A Yes, free samples of 500 mL are available for qualified US companies. Shipping fee applies for small quantities.
Q5 Can benzyl benzoate be used as a topical treatment for scabies?
A Yes, benzyl benzoate is a well established active ingredient in topical lotions for scabies and lice. Please consult your regulatory team for formulation and registration requirements.
Q6 What are the common impurities and how do you control them?
A Key impurities include benzyl alcohol, benzoic acid, and dibenzyl ether. Our specification limits each below 0.2 percent. Full impurity profiling is provided with each certificate.
Q7 Is benzyl benzoate safe for use in cosmetics?
A Yes, it is widely used in cosmetics as a fixative and solvent. It is listed in the FDA's database of approved cosmetic ingredients. However, it may cause contact dermatitis in sensitive individuals; proper dilution is recommended.
