| Description |
As an organic compound, Cinnamic alcohol has a very distinct sweet, spicy, hyacinth odour that is found in resins, balsams and cinnamon leaves. It is used commonly in the fragrance industry due to its distinctive odour, which can be applied as a deodorant, fragrance and additive in cosmetic products and in the formulation of bath products, body and hand products, such as soaps, toothpaste, deodorants, etc. Besides, it also finds application as a food additive in chewing gum, bakery products, candy and soft drinks. Naturally, Cinnamyl alcohol is occurrent only in small amount, thus its industrial demand is usually fulfilled by chemical synthesis starting from the reduction of cinnamaldehyde.
Cinnamyl alcohol has been found to have a sensitising effect on some particular people, thus it is also considered as a Standardized Chemical Allergen. The physiologic effect of cinnamyl alcohol is caused by the Increased Histamine Release and cell-mediated Immunity. |

| Chemical Properties |
colourless solid |
| Uses |
Cinnamyl alcohol was used to study the alkylation of 2,4-di-tert-butylphenol by cinnamyl alcohol using aluminum-containing mesoporous ethane-silica catalyst. It was used to study gold nanoparticles supported on titanium dioxide catalysed oxidative coupling of alcohols and amines to form the corresponding imines. |
| Uses |
cinnamyl alcohol is naturally occurring in cinnamon bark, it can also be synthetically manufactured. It is used in cosmetics as a fragrance or flavoring agent. |
| Uses |
In perfumery; as deodorant in 12.5% solution in glycerol. |
| Definition |
ChEBI: A primary alcohol comprising an allyl core with a hydroxy substituent at the 1-position and a phenyl substituent at the 3-position (geometry of the C2C bond unspecified). |
| Contact allergens |
Cinnamyl alcohol occurs (in esterified form) in storax, Myroxylon pereirae, cinnamon leaves, and hyacinth oil. It is obtained by the alkaline hydrolysis of storax and prepared synthetically by reducing cinnamal diacetate with iron filings and acetic acid, and from cinnamaldehyde by Meerwein-Ponndorf reduction with aluminum isopropoxide. Cinnamic alcohol is contained in the “fragrance mix.” As a fragrance allergen, it has to be mentioned by name in cosmetics within the EU. Occupational cases of contact dermatitis were reported in perfume industry. Patch tests can be positive in food handlers. |
| Purification Methods |
Crystallise the alcohol from diethyl ether/pentane. [Beilstein 6 I 281.] |
