Is Eugenol Flammable? 

This article will answer the question, is Eugenol flammable? It also covers several topics about Eugenol, its characteristics, its applications, and the treatments to avoid fire ignition from Eugenol exposure.

Is Eugenol Flammable?

Yes, eugenol is a flammable chemical compound with a flammability category level 2 according to NFPA 704. It must be heated up or subjected to high temperatures before it may catch fire.

What is Eugenol?

Eugenol is a type of chemical compound of phenylpropanoid. Eugenol is a chemical in several plants, such as basil, cinnamon, and nutmeg. However, Eugenol is commonly referred to as “clove oil” because this chemical is widely found in clove oil. 

The content of this molecule is the major component in the essential oil extracted from cloves with a dosage of 72 percent to 90 percent. This chemical is mildly soluble in water and soluble in organic solvents.

In the scientific community, Eugenol (C10H12O2) is known as 2-methoxy-4-(2-propenyl)phenol, a guaiacol derivative with an extra allyl ring. Allylbenzene is a family of phenolic compounds that includes this one.

What are the Properties of Eugenol?

In terms of its appearance and fragrance, Eugenol is a colorless or pale yellow liquid with a pungent cloves-like aroma. When exposed to oxygen, it darkens and thickens. 

Organic solvents, including chloroform, ether, and alcohol, as well as water, are all excellent sources of Eugenol’s solubles and volatiles. Eugenol’s lipophilic nature in bacteria can promote cell membrane adhesion, inhibiting respiration. 

Eugenol’s antioxidant, anticancer, and antiseptic properties make it a valuable commodity for the pharmaceutical sector. It comprises allyl (-CH2-CH=CH2), phenol (-OH), and methoxy functional groups in Eugenol (-OCH3). 

The reactive groups in Eugenol can be employed as a starting point for synthesizing more valuable compounds, such as isoeugenol, eugenol acetate, benzyl eugenol, and methyl eugenol, eugenol methyl ether, and vanillin.

Another property of Eugenol is:

  • Formula: C10H12O2
  • Bulk point: 254 °C
  • Molar mass: 164.2 g/mol
  • Melting point: -7.5 °C
  • Density: 1.06 g/cm³
  • IUPAC ID: 4-Allyl-2-methoxy phenol

What are the Utilizations of Eugenol?

Industry of Pharmaceuticals

Compounds derived from eugenol exhibit pharmacological activity in analgesia, inflammation, antiviral, antifungal, antispasmodic, antispasmodic-antiemetic, stimulant, and local anesthetic.

  • Eugenol combined with zinc oxide is commonly used in dentistry as a compound cementing agent.
  • In treating pulpitis, Eugenol’s capacity to prevent the transmission of nerve impulses has been highly beneficial.
  • Eugenol is commonly used as a raw material for mouthwash, toothpaste, toilet water, antiseptic liquid, antiseptic wipes, and spray because of its ability to inhibit the growth of bacteria.
  • There are many uses for the compounds of Eugenol, such as in ointments that can be used to alleviate rheumatoid arthritis pain.
  • Pramod (2010) showed that Eugenol’s antioxidant properties make it a promising treatment for Parkinson’s disease and heart hypertrophy.
  • When given intravenously to guinea pigs, Eugenol can relieve fever more effectively than the regularly used fever-reducing drug acetaminophen.
  • The fungus Candida albicans, which causes candidiasis, is inhibited in vitro and in vivo by Eugenol, according to several studies.
  • Eugenol has been shown to have antiviral efficacy against both HSV and hepatitis C, according to Chaieb et al. (2007).
  • To make bibenzyl compounds with antimitotic and antileukemic action from synthetic vanilla chemicals, which are eugenol derivatives, research is now being conducted on their usage as cytotoxic agents in cancer cells.

Industry of Active Packaging

  • Compounds derived from the eugenol plant have antibacterial qualities that can be used in food packing cartons.
  • The antioxidant and antibacterial characteristics of eugenol molecules and their derivatives can be exploited in producing edible coatings and edible films.

The Pesticide Industry in Vegetables

  • Because numerous studies have shown that eugenol compounds are effective in suppressing nematodes, pathogenic fungus, bacteria, and insect pests, clove eugenol can be used as raw material for vegetable pesticides.
  • Larvicides like Eugenol can be employed because it affects the mortality of mosquito larvae and can eliminate adult mosquitoes.
  • It is possible to employ the methyl eugenol compound as an attractant for male fruit flies in controlling fruit flies.

Consumer Products and the Tobacco Industry

  • Non-alcoholic beverages, ice cream, chewing gum, and other foods can benefit from the flavoring additions made possible by Eugenol and its derivatives.
  • Generic versions of the flavoring agent vanilla (C8H8O3) can be created from eugenol compounds, and synthetic arrangements of this flavoring agent can be made from eugenol compounds.
  • Spicey and hot clove flavors are two characteristics of Eugenol. Hence it is commonly used to improve the flavor of kretek cigarettes’ chopped cloves.

Other Chemical Companies

Antioxidants derived from Eugenol, such as those found in cosmetics and pharmaceuticals, as well as in the plastics and rubber sectors, are widely employed.

The chemical eugenol acetate can raise the cetane number of diesel fuel as a bio additive, hence improving diesel fuel performance.

What is the Treatment to Avoid Fire Ignition from Eugenol Exposure?

A dry chemical, carbon dioxide, or Halon extinguisher can be used to put out a blaze involving this material. Alternatively, a water spray might be employed.

Conclusion

Eugenol is categorized as a flammable chemical. However, it is used in various industries due to its characteristics. Please comment down below if you have more questions about eugenol.

Frequently Asked Question (FAQs): Is Eugenol Flammable?

Does Eugenol Pose a Health Risk?

Large quantities can induce liver and gastrointestinal damage if ingested. Bronchitis, disorientation and shallow breathing might result from inhaling this chemical. 

Skin-to-skin contact can inflame the skin. The skin may become inflamed as a result of prolonged or repeated touch.

Is Eugenol Volatile?

Just one enzyme in the Gymnadenia genus can catalyze the conversion of the floral volatile fragrance molecules eugenol and isoeugenol. The gene encoding this enzyme is currently the only one in these species that have been functionally described.
