Benzyl benzoate is a versatile compound used across multiple industries, functioning as an active ingredient, fragrance fixative, and industrial plasticizer/solvent.
Healthcare:
Antiparasitic Agent: The primary active ingredient in topical lotions and creams for the treatment of scabies (caused by Sarcoptes scabiei mites). It is also used against lice.
Excipient: Used as a solvent or co-solvent to dissolve poorly water-soluble in topical formulations.
Fragrance & Cosmetics Industry:
Fragrance Fixative: Widely used as a fixative in perfumes, soaps, and cosmetic fragrances to slow the evaporation of more volatile fragrance components, making the scent last longer.
Cosmetic Ingredient: Functions as a plasticizer and solvent in nail polishes, hair sprays, and other film-forming products.
Industrial Applications:
Plasticizer: Used as a specialty plasticizer for cellulose acetate, nitrocellulose, and natural rubber to improve flexibility.
High-Boiling Solvent: Employed in the manufacture of inks, paints, and dyes due to its strong solvating power.
Other Uses: Historically used as a repellent; minor use as a food flavoring agent; and as a chemical intermediate in synthesis.
