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. The use of sodium hydroxide in the hydrolysis of benzyl chloride yields benzyl alcohol and sodium chloride as the products. The chemical equation for this reaction is given by: NaOH + C6H5CH2Cl → NaCl + C6H5CH2OH An alternate method of preparing this compound involves the Grignard reaction between formaldehyde (H-CHO) and phenylmagnesium bromide (Ph-Mg-Br).   Benzyl alcohol is found in many naturally occurring plant products such as Balsam of Peru and is also a component of essential oils such as hyacinth, jasmine, and ylang ylang oils. Benzyl alcohol is also prevalent in hair dyes, shampoos, facial cleansers, sunscreens, fragrances, and cosmetics.
