Benzyl Benzoate is a simple ester‑based ingredient with a subtle resin‑like fragrance. It occurs naturally in Peruvian cedar, Turan cedar, as well as multiple essential oils including ylang‑ylang, hyacinth and night‑blooming jasmine, lending it wide adoption within pharmaceutical and fragrance industries. While practically insoluble in water, it exhibits outstanding solubility in organic solvents. It performs reliably under high‑temperature processing conditions and functions as a dedicated solvent for certain musk raw materials.
Further strengthened by low volatility, superior solvent capacity and the intrinsic chemical stability of its ester structure, Benzyl Benzoate delivers remarkable comprehensive performance. Moreover, it possesses powerful insecticidal activity, showing prominent efficacy against fleas, lice, ticks and scabies mites, and outperforms sulfur in treatment effect. Featuring non‑irritating and non‑greasy characteristics, it gains extra formulation advantages. It is frequently compounded with dibenzyl sulfide ester to achieve optimized insect‑repellent performance.

Benzyl Benzoate is a naturally‑occurring ester ingredient with delicate resin‑like aroma. Insoluble in water yet highly miscible with organic solvents, it features low volatility, excellent solvent performance and stable ester‑group structure. It works as an ideal solvent for high‑temperature processes and special musk raw materials. Besides its wide applications in fragrance and pharmaceutical formulations, it delivers powerful insecticidal efficacy against fleas, lice, ticks and scabies mites with efficiency superior to sulfur. Non‑irritating and non‑greasy, it can also be compounded with dibenzyl sulfide ester to further strengthen insect‑repellent effects.
