Phenethyl alcohol, or 2-phenylethanol, is the organic compound with the formula C6H5CH2CH2OH. This colourless liquid occurs widely in nature, being found in a variety of essential oils, including rose, carnation, hyacinth, Aleppo pine, orange blossom, ylang-ylang, geranium, neroli, and champaca. It is slightly soluble in water (2 mL/100 mL H2O), but miscible with ethanol and ether.
Phenethyl alcohol is an alcohol with a pleasant floral odor. It is therefore a common ingredient in flavors and perfumery, particularly when the smell of rose is desired. It is also used as a preservative in soaps due to its stability in basic conditions. In biology it is of interest due to its antimicrobial properties.
