• Beschreibung

  Sensitization to eugenol mainly occurs in those in dental professions. Eugenol is contained in the "fragrance mix".

• Chemische Eigenschaften

  colourless to faintly yellow liquid with a strong odour of cloves

• Chemische Eigenschaften

  Eugenol has a strong aromatic odor of clove and a spicy, pungent taste. It darkens and thickens on exposure to air.

• Chemische Eigenschaften

  Eugenol is the main component of several essential oils; clove leaf oil and cinnamon leaf oilmay contain>90%.Eugenol occurs in small amounts in many other essential oils. It is a colorless to slightly yellow liquid with a spicy, clove odor.
  Catalytic hydrogenation (e.g., in the presence of noble metal catalysts) yields dihydroeugenol. Isoeugenol is obtained fromeugenol by shifting the double bond. Esterification and etherification of the hydroxy group of eugenol yield valuable fragrance and flavor materials (e.g., eugenol acetate and eugenol methyl ether).

• Occurrence

  Reported found as a constituent in several volatile oils: clove oil, laurel and cinnamon leaf oil. Smaller amounts of eugenol are also present in the oil of camphor, Java citronella, California laurel and acacia flowers; remarkable amounts of eugenol are found in Ocimum sanctum (70%) and Ocimum gratissimum (60%). Eugenol is also found in the oil from violet flowers (21%); in some plants, eugenol probably occurs as glucoside. Reported found in apricot, citrus oils, raspberry, strawberry, tomato, anise, cinnamon (leaf, bark and roots), clove bud and stem, nutmeg, mace, pepper, smoked fish, beer, whiskey, grape wines, cocoa, mango, tarragon, laurel, myrtle leaf, and pimento berry and leaf.

• Verwenden

  blood volume expander

• Verwenden

  Eugenol is a dental compound which shows cytotoxicity to human oral squamous cell carcinoma and oral cells. When glucosylated, this compound exhibits anti-inflammatory activity.

• Verwenden

  Eugenol is a flavoring obtained from clove oil and also found in car- nation and cinnamon leaves. it is a stable, light yellow-green liquid of clove odor. it is slightly soluble in water and miscible in alcohol. it should be stored in glass or tin, avoiding iron containers. it is used in spice oils for application in condiments and meats at 100–200 ppm and in baked goods and candy at approximately 30 ppm.

• Verwenden

  eugenol is a botanical fraction. It is anti-bacterial, anti-inflammatory, and pain relieving. It can also be used as a local, topical anesthetic and antiseptic. In a cosmetic formulation, it can mask odor or provide fragrance. eugenol is a yellow, oily liquid and is generally associated with clove oil. However, it is also found in nutmeg, cinnamon, and bay leaf.

• Verwenden

  analgesic (topical), antiseptic, antifungal

• synthetische

  Since sufficient eugenol can be isolated from cheap essential oils, synthesis is not industrially important. Eugenol is still preferentially isolated from clove leaf and cinnamon leaf oil (e.g., by extraction with sodium hydroxide solution). Nonphenolic materials are then removed by steam distillation. After the alkaline solution is acidified at low temperature, pure eugenol is obtained by distillation.

• Definition

  ChEBI: A phenylpropanoid formally derived from guaiacol with an allyl chain substituted para to the hydroxy group.

• Aroma threshold values

  Detection: 6 to 100 ppb

• Allgemeine Beschreibung

  Clear colorless pale yellow or amber-colored liquid. Odor of cloves. Spicy pungent taste.

• Air & Water Reaktionen

  Darkens and thickens on exposure to air. Also darkens with age. Eugenol may decompose on exposure to light. Insoluble in water.

• Reaktivität anzeigen

  Eugenol is incompatible with strong oxidizers. This includes ferric chloride and potassium permanganate. Eugenol reacts with strong alkalis. Eugenol is incompatible with iron and zinc.

• Hazard

  Questionable carcinogen.

• Brandgefahr

  Eugenol is combustible.

• Kontakt-Allergie

  Eugenol is a fragrance allergen obtained from many natural sources. Occupational sensitization to eugenol may occur in dental profession workers. Eugenol is contained in “fragrance mix” and has to be listed by name in cosmetics within the EU.

• Clinical Use

  4-Allyl-2-methoxyphenol is obtained primarily from cloveoil. It is a pale-yellow liquid with a strong aroma of clovesand a pungent taste. Eugenol is only slightly soluble in waterbut is miscible with alcohol and other organic solvents.Eugenol possesses both local anesthetic and antiseptic activityand can be directly applied on a piece of cotton to relievetoothaches. Eugenol is also used in mouthwashes because ofits antiseptic property and pleasant taste. The phenol coefficientof eugenol is 14.4.

• Anticancer Research

  This compound was tested on a model of skin tumor induced by DMBA croton oilin Swiss mice. The eugenol affects the cellular proliferation by increasing apoptosiscellular death. There is evidence for a downregulation of c-myc, H-ras, and Bcl-2expression and an upregulation of p53, Bax, and active caspase-3 (Grondona et al.2014).

• Sicherheitsprofil

  Moderately toxic by ingestion, intraperitoneal, and subcutaneous routes. Human mutation data reported. A human skin irritant. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALLYL COMPOUNDS.

• Synthese

  The oil containing eugenol is treated with a 3% aqueous solution of NaOH; the nonacid components are extracted with ether; the alkaline solution is acidified to isolate the phenols and subsequently is fractionally distilled under reduced pressure; to avoid the formation of emulsions, a pretreatment of the oil with tartaric acid is preferred; eugenol is the starting material in one of the syntheses for the preparation of vanillin.

• Stoffwechsel

  No absorption of eugenol occurred within 2hr of application to the intact shaved skin of mice (Meyer & Meyer, 1959). Following ip injec tion of [¹⁴C]eugenol into rats, radioactivity was dis tributed in various organs and the presence of ¹⁴CO₂ in the expired air indicated the demethylation of eugenol (Weinberg, Rabinowitz, Zanger & Gennaro, 1972). Over 70% of an oral dose of eugenol was excreted in the urine of rabbits (Schr?der & Vollmer, 1932).

• läuterung methode

  Fractional distillation of eugenol gives a pale yellow liquid which darkens and thickens on exposure to air. It should be stored under N2 at -20o. [Waterman & Priedster Recl Trav Chim Pays-Bas 48 1272 1929, Beilstein 6 H 961, 6 IV 6337.]
