benzoin is a fragrant essential oil with bactericidal, anti-irritation, and anti-itching properties. It is considered a good ingredient for reducing skin redness and is a preservative of fats. Although its primary constituent is benzoic acid, it also contains canillin and an oily aromatic liquid. This balsamic resin is extracted by cutting deeply into the trunks of trees that grow primarily in Indonesia and Thailand. | [CAS DataBase Reference]

light yellow powder or crystals with a camphor-like odour | [Occurrence]
Benzoin is a resin from the trees of genus Styrax. | [Definition]
benzoin: A colourless crystallinecompound, C6H5CHOHCOC6H5; m.p.137°C. It is a condensation product ofbenzenecarbaldehyde (benzaldehyde),made by the action of sodiumcyanide on benzenecarbaldehyde inalcoholic solution. It also occurs naturallyas the resin of a tropical tree. Itis both a secondary alcohol and a ketone,and gives reactions characteristicof both types of compound. | [Definition]
ChEBI: A ketone that consists of acetophenone bearing hydroxy and phenyl substituents at the alpha-position. The parent of the class of benzoins. | [Taste threshold values]
Taste characteristics at 25 ppm: spicy, balsamic, resinous, fruity with an herbal nuance. | [Safety Profile]
Slightly toxic by ingestion andskin contact. Mutation data reported. A flammable liquid.When heated to decomposition it emits acrid smoke andirritating fumes. | [Synthesis]
It may be prepared by condensation of benzaldehyde with an alkali cyanide and used in organic synthesis. | [storage]
Store at -20°C | [Purification Methods]
Crystallise benzoin from CCl4, hot EtOH (8mL/g), or 50% acetic acid. Also crystallise it from high purity *benzene, then twice from high purity MeOH, to remove fluorescent impurities [Elliott & Radley Anal Chem 33 1623 1961]. It can be sublimed. [Beilstein 8 IV 1279.] | [Toxics Screening Level]
The initial threshold screening level (ITSL) for benzoin is 32 μg/m3 based on an annual averaging time. |
