• Beschreibung

  Occupational cases of contact dermatitis were reported in the perfurne industry. Patch tests can also be positive in food handlers. Cinnamic alcohol is contained in the "fragrance mix".

• Chemische Eigenschaften

  Cinnamyl alcohol can exist in (Z)-[4510-34-3] and (E)-[4407-36-7] forms. Although both isomers occur in nature, the (E)-isomer is far more abundant and is present, for example, in styrax oil. (E)-Cinnamyl alcohol is a colorless, crystalline solid with a hyacinth-like balsamic odor.
  Cinnamyl alcohol can be dehydrogenated to give cinnamaldehyde and oxidized to give cinnamic acid. Hydrogenation yields 3-phenylpropanol and/or 3-cyclohexylpropanol. Reaction with carboxylic acids or carboxylic acid derivatives results in the formation of cinnamyl esters, some of which are used as fragrance materials.

• Chemische Eigenschaften

  Cinnamyl alcohol has a pleasant, floral odor and bitter taste.

• Occurrence

  Occurring as an ester or in the free state in hyacinth, Aristolochia clematis, Xanthorrhoea hastilis and in the essence of daffodil flowers. It is also reported found in guava fruit and peel, lemon peel oil, cassia leaf, Bourbon vanilla and cinnamon bark, leaf and root.

• Verwenden

  Cinnamic alcohol is a component in perfumed cosmetic products and deodorants; some perfumery uses (cinnamon; daffodil; hyacinth; jasmine); natural occurrence (cinnamon).

• Verwenden

  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.In perfumery; as deodorant in 12.5% solution in glycerol.

• Verwenden

  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.

• 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).

• synthetische

  By reduction of cinnamic aldehyde.

• Aroma threshold values

  Detection: 1 ppm; cis- form, 81 ppb; trans- form, 2.8 ppm

• Taste threshold values

  Taste characteristics at 20 ppm: green, floral, spicy and honey with a fermented yeasty nuance.

• Flammability and Explosibility

  Not classified

• Kontakt-Allergie

  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. Cinnamyl 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.

• Synthese

  Obtained originally by saponification of extraction from storax; synthetically, by reduction of cinnamaldehyde with sodium or potassium hydroxide.

• läuterung methode

  Crystallise the alcohol from diethyl ether/pentane. [Beilstein 6 I 281.]
