2-Phenylethanol activates preservatives in soap and additives for cigarettes [1]. 2. Phenylethyl alcohol inhibits the growth of dyes that are Gram-negative [1].

| ln Vivo |
In mice, 2-phenylethanol (5%; breathed) decreases depressive-like behavior and enhances anxiety-like behavior [3].
Inhalation of 2-phenylethanol (2-PE) in mice decreased immobility time in the tail suspension test, suggesting an anti-depressive-like effect. However, in the open field test, mice spent less time in the center area, indicating increased anxiety-like behavior. No changes were observed in cognitive function, activity level, muscle strength, or aggression. In the elevated plus maze test, no significant difference was observed in the percentage of open arm entries or time spent in open arms compared to control. In the Y-maze test, no significant difference was observed in spatial working memory. In the sucrose preference test, no change in sucrose consumption was observed, indicating no effect on anhedonia-like behavior. In the Porsolt forced swim test, no significant difference in immobility time was observed compared to control. |
| Animal Protocol |
Animal/Disease Models: 11weeks old male mice (C57BL/6) [3]
Doses: 5% (v/v) Route of Administration: inhalation; Experimental Results:It exerts an antidepressant-like effect, but may increase anxiety-like behaviors. Male C57BL/6 mice (11 weeks old) were used. 2-phenylethanol was diluted to 5% (v/v) in 1% Tween 80 and impregnated into absorbent cotton placed in a sealed container. Mice were exposed to 2-PE vapor for 15 minutes in a three-layer cage system before behavioral tests. Control mice were exposed to 1% Tween 80 only. Behavioral tests included: odor preference test, elevated plus maze, open field test, Y-maze test, tail suspension test, Porsolt forced swim test, sucrose preference test, grip strength test, and cotton bud biting test. All tests were performed during the light phase, with at least one day between tests. Apparatus was cleaned with 70% ethanol and super-oxidized hypochlorous acid between trials. |
| ADME/Pharmacokinetics |
Metabolism / Metabolites
2-Phenylene alcohol is converted to phenylacetaldehyde in rabbits: Smith JM et al., BIOCHEM J, 56, 320, 1954. /Excerpt from Table/ Phenylene alcohol is almost completely oxidized to the corresponding acid. Following oral administration of 0.2 to 0.3 g/kg doses to rabbits, the metabolites excreted in the urine included: phenylacetic acid urate, a glycine conjugate of phenylacetic acid, 42%; glucuric acid, 5%; and an ether-soluble acid, possibly phenylacetic acid, 19%. This explains only 66% of the original dose. Phenylene alcohol… β-Phenylene alcohol is a substrate for ADH, with an initial oxidation rate almost as high as allyl alcohol and significantly higher than ethanol. |

| Additional Infomation |
2-Phenylacetylethanol is a primary alcohol, a product of ethanol with a phenyl group substituted at the 2-position. It is used as a fragrance, a metabolite of Saccharomyces cerevisiae, a plant metabolite, a metabolite of Aspergillus, and a plant growth inhibitor. It is a primary alcohol belonging to the benzene family. It is an antibacterial agent, preservative, and disinfectant, and is also used as a fragrance and preservative in pharmaceuticals and perfumes. 2-Phenylacetylethanol has been reported to exist in Saccharomyces cerevisiae, tea trees, and other organisms with relevant data. 2-Phenylacetylethanol is a metabolite of or produced by Saccharomyces cerevisiae. It is an antibacterial agent, preservative, and disinfectant, and is also used as a fragrance and preservative in pharmaceuticals and perfumes. See also: Moringa leaf oil (partial).
Therapeutic Uses Topical anti-infective agent; disinfectant; medicinal preservative. Phenylacetylethanol… was once used as an antibacterial agent in ophthalmic solutions at a concentration of 0.5%. Phenylacetylethanol (2-phenylethanol) is the main aroma component of rose oil. It has traditionally been used in aromatherapy to treat mental illnesses, but its scientific basis remains unclear. This study suggests that inhaling 2-phenylethanol may exert an antidepressant effect through the olfactory system, but may also induce anxiety-like behavior in certain situations. The study also indicates that the effects of rose oil and 2-phenylethanol may vary depending on concentration, duration of exposure, and route of administration. |
