BA / BB Benzyl Alcohol  Pharmaceutical Intermediates Colorless Liquid

 

Benzyl alcohol is an aromatic alcohol with the formula C6H5CH2OH. The benzyl group is often abbreviated "Bn" (not to be confused with "Bz" which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is a useful solvent due to its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and miscible in alcohols and diethyl ether. 

 

Applications

 

Benzyl alcohol is used as a general solvent for inks, waxes, shellacs, paints, lacquers, and epoxy resin coatings. Thus it can be used in paint strippers, especially when combined with compatible viscosity enhancers to encourage the mixture to cling to painted surfaces. It is a precursor to a variety of esters, used in the soap, perfume, and flavor industries.

 

It is also used in e-liquid for e-cigarettes to enhance the flavors used. When applied to damaged skin or mucous membranes at a 10% concentration it acts as a local anesthetic and antimicrobial agent, and is sometimes included as a degreaser in rug cleaning products. As a dye solvent, it enhances the process of dying wool, nylon, and leather. It also has use as a photographic developer, and as an insect repellent.

 

Nanotechnological uses

 

Benzyl alcohol has been used as a dielectric solvent for the dielectrophoretic reconfiguration of nanowires.

 

Use in health care

 

Benzyl alcohol is used as a bacteriostatic preservative at low concentration in intravenous medications, cosmetics and topical drugs.

 

The use of benzyl alcohol as a 5% solution has been approved by the U.S. FDA for the treatment of head lice in children older than 6 months and in adults. It affects the louse's spiracles, preventing them from closing. These then become clogged with water or mineral oil or other matter and cause the insect to die from asphyxiation.

 

Other uses

 

Benzyl alcohol has nearly the same refraction index of quartz and wool fiber. If a clear quartz object is immersed in benzyl alcohol, it becomes almost invisible. This test has been used to determine non-destructively whether an object is truly made of quartz (see crystal skull). Similarly, white wool immersed in benzyl alcohol also becomes almost invisible clearly revealing contaminants such as dark and medullated fibers and vegetable matter.
