安全と保護具
Fire Fighting
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)
Use water spray, powder.
First Aid Measures
Fresh air, rest.
Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Personal Protective Equipment (PPE)
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Non-Human Toxicity Excerpts
Benzoin was found to be negative when tested for mutagenicity using the Salmonella/microsome preincubation assay, using the standard protocol approved by the National Toxicology Program (NTP). Benzoin was tested in as many as 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of rat and hamster liver S-9, at doses of 0.033, 0.0333, 0.100, 0.333, 0.3333, 0.667, 1.000, and 3.3333 mg/plate. The highest ineffective dose tested in any S. typhimurium strain was 3.3333 mg/plate. Precipitate was observed in most cultures at the high dose and also some clearing of the background bacterial lawn was also seen.
... Levels of Evidence of Carcinogenicity: Male Rats: Negative; Female Rats: Negative; Male Mice: Negative; Female Mice: Negative.
National Toxicology Program Studies
A bioassay of benzoin for possible carcinogenicity was conducted by incorporating the test chemical in diets of F344 rats and B6C3F1 mice. ... Groups of 50 male rats were fed diets containing 125 or 250 ppm benzoin for 104 wk, and similar groups of female rats received feed containing 250 or 500 ppm. Groups of 50 mice if each sex were fed diets containing 2,500 or 5,000 ppm benzoin for 104 wk. Groups of 50 untreated rats and mice of each sex were used as matched controls. ... Under the conditions of this bioassay, benzoin was not carcinogenic in F344 rats or B6C3F1 mice. Levels of Evidence of Carcinogenicity: Male Rats: Negative; Female Rats: Negative; Male Mice: Negative; Female Mice: Negative.

天然物の起源Benzoin is a resin from the trees of genus Styrax.
使用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.
一般的な説明Off-white to yellow-white crystalline solid with an odor of camphor. Slightly acrid taste. When broken the fresh surfaces have a milky-white color.
使用用途ベンゾインは、分析用試薬として使用されます。ベンゾインを使用することで、とケイ光反応が起きます。そのため、少量の亜鉛イオンを検出することが可能です。 また、ベンゾインという名前で精油として売られています。これは、熱帯の高木の樹脂から抽出されるものです。甘く、バニラのような香りがし、心を落ち着かせる効果があります。 そのほか、酸化防止剤として、オイルの持ちを良くする役割もあります。
調製方法
純化方法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.]
