Benzyl benzoate Usage And Synthesis
- DescriptionBenzyl benzoate (BnBzO) is a mediation and insect repellent. It is one of the older preparation used to treat scabies which is a skin infections caused by the mite scarcoptes scabiei since it is lethal to the mite. It is capable of killing the mite in 5 minutes. It can also be used for the treatment of lice infestation of the head and the body. Its mechanism of action is through exerting toxic effect on the nervous system of the insects, further causing its death. It is also toxic to mite ova through an unknown mechanism. It can also be used as a repellent for chiggers, ticks, and mosquitoes as well as a dye carrier, solvent of cellulose derivatives, plasticizer, and a fixative.
- Chemical PropertiesBenzyl benzoate is a clear, colorless, oily liquid with a light, balsamic odor reminiscent of almond and a sharp, pungent taste. It produces a sharp, burning sensation on the tongue. At temperatures below 178℃ it exists as clear, colorless crystals.
- UsesBenzyl Benzoate has seen use as an insecticide, as well as a solvent for various chemical reactions.
- DescriptionBenzyl benzoate is the ester of benzyl alcohol and benzoic acid, with the formula C6H5CH2O2CC6H5. This easily prepared compound with a mild balsamic odor has a variety of uses.
- Chemical PropertiesBenzyl Benzoate is the main component of Peru balsam oil. It occurs in fairly large amounts in a number of blossom concretes and absolutes (e.g., tuberose and hyacinth). It forms either a viscous liquid or solid flakes (mp 21–22°C) and has a weak, sweet, balsamic odor.
Benzyl Benzoate is prepared either by transesterification of technical methyl benzoate with benzyl alcohol or from benzyl chloride and sodium benzoate. A third process starts with benzaldehyde, which is converted in high yield into benzyl benzoate in the presence of sodium or aluminum benzylate (Tishchenko reaction). Benzyl benzoate is used in perfumery as a fixative and as a modifier in heavy blossom fragrances.
- OccurrenceContained in Peru balsam and in the concrete and absolute of tuberose flowers, hyacinth, Narcissus jonquilla L., and Dianthus caryophillus L.; also in the oil of ylang-ylang and in Tolu balsam. Reported found in American cranberry, cinnamon bark, cassia leaf, corn oil and hog plum (Spondias mombins L.).
- UsesBenzyl benzoate, as a topical solution, may be used as an antiparasitic insecticide to kill the mites responsible for the skin condition scabies , for example as a combination drug of benzyl benzoate/disulfiram.
It has other uses :
a fixative in fragrances to improve the stability and other characteristics of the main ingredients
a food additive in artificial flavors
a plasticizer in cellulose and other polymers
a solvent for various chemical reactions
a treatment for sweet itch in horses
a treatment for scaly leg mites in chickens.
- Usesbenzyl benzoate is an anti-microbial. It can also act as a solvent, helping dissolve other substances in the product, and as a perfuming ingredient. It is the ester of benzyl alcohol and benzoic acid.
- UsesAs solvent of cellulose acetate, nitrocellulose and artificial musk; substitute for camphor in celluloid and plastic pyroxylin Compounds; perfume fixative; in confectionery and chewing gum flavors.
- Production MethodsBenzyl benzoate is a constituent of Peru balsam and occurs naturally in certain plant species. Commercially, benzyl benzoate is produced synthetically by the dry esterification of sodium benzoate and benzoyl chloride in the presence of triethylamine or by the reaction of sodium benzylate with benzaldehyde.
- Production MethodsBENZYL BENZOATE is produced by the Cannizzaro reaction from benzaldehyde, by esterifying benzyl alcohol with benzoic acid, or by treating sodium benzoate with benzyl chloride. It is purified by distillation and crystallization. Benzyl benzoate is used as a fixative and solvent for musk in perfumes and flavors, as a plasticizer, miticide, and in some external medications. The compound has been found effective in the treatment of scabies and pediculosis capitis (head lice, Pediculus humanus var. capitis).
- PreparationBy the dry esterification of sodium benzoate and benzoyl chloride in the presence of triethylamine or by reaction of sodium benzylate on benzaldehyde.
- brand namePharmaceutic necessity for Dimercaprol [Injection]. Benylate (Sterling Winthrop).
- Taste threshold valuesTaste characteristics at 30 ppm: balsamic, fruity with powdery and berry nuances.
- HazardIrritant to eyes, skin.
- Pharmaceutical ApplicationsBenzyl benzoate is used as a solubilizing agent and nonaqueous
solvent in intramuscular injections at concentrations of
0.01–46.0% v/v, and as a solvent and plasticizer for cellulose
and nitrocellulose. It is also used in the preparation of spray-dried
powders using nanocapsules.
However, the most widespread pharmaceutical use of benzyl benzoate is as a topical therapeutic agent in the treatment of scabies. Benzyl benzoate is also used therapeutically as a parasiticide in veterinary medicine.
Other applications of benzyl benzoate include its use as a pediculicide, and as a solvent and fixative for flavors and perfumes in cosmetics and food products.
- Contact allergensBenzyl benzoate is the ester of benzyl alcohol and benzoic acid. It is contained in Myroxylon pereirae and Tolu balsam. It is used in acaricide preparations against Sarcoptes scabiei or as a pediculicide. Direct contact may cause skin irritation, but rarely allergic contact dermatitis. As a fragrance allergen, benzyl benzoate has to be mentioned by name in EU cosmetics.
- Clinical UseBenzyl benzoate is a naturally occurring ester obtained fromPeru balsam and other resins. It is also prepared syntheticallyfrom benzyl alcohol and benzoyl chloride. The ester isa clear colorless liquid with a faint aromatic odor. It is insolublein water but soluble in organic solvents.
Benzyl benzoate is an effective scabicide when appliedtopically. Immediate relief from itching probably resultsfrom a local anesthetic effect; however, a complete cureis frequently achieved with a single application of a 25%emulsion of benzyl benzoate in oleic acid, stabilized withtriethanolamine. This preparation has the additionaladvantage of being essentially odorless, nonstaining, andnonirritating to the skin. It is applied topically as a lotionover the entire dampened body, except the face.
- SafetyBenzyl benzoate is metabolized by rapid hydrolysis to benzoic acid
and benzyl alcohol. Benzyl alcohol is then further metabolized to
hippuric acid, which is excreted in the urine.
Benzyl benzoate is widely used as a 25% v/v topical application in the treatment of scabies and as an excipient in intramuscular injections and oral products. Adverse reactions to benzyl benzoate include skin irritation and hypersensitivity reactions. Oral ingestion may cause harmful stimulation of the CNS and convulsions. Benzyl benzoate should be avoided by perople with perfume allergy.
