Eugenol is a naturally occurring aromatic phenolic compound found predominantly in clove oil, as well as in cinnamon, bay leaf and other botanical sources. It is an important specialty ingredient used in fragrance, personal-care and cosmetic formulations because of its characteristic warm, spicy, clove-like aroma and documented functional properties.
Eugenol has the molecular formula C₁₀H₁₂O₂ and a molecular weight of 164.20 g/mol. It is generally supplied as a clear, colourless to pale-yellow liquid with a distinctive clove odor. Its combination of aromatic character, phenolic functionality and compatibility with oils makes Eugenol an important raw material for fragrance and personal-care applications.
Eugenol is also a naturally occurring component of clove essential oil and has been extensively studied for antimicrobial and antioxidant properties.
Eugenol is identified by CAS Number 97-53-0 and EC Number 202-589-1. Its chemical name is 4-Allyl-2-methoxyphenol, with other names including 2-Methoxy-4-(2-propenyl)phenol, Allylguaiacol and 4-Allylguaiacol.
Eugenol has a molecular formula of C₁₀H₁₂O₂ and a molecular weight of 164.20 g/mol. It has a melting point around −10 to −7°C, meaning that it is normally handled as a liquid at room temperature. Its boiling point is approximately 254–256°C.
The material is slightly soluble in water and soluble in ethanol, ether and many fixed oils. JECFA describes Eugenol as a colourless to pale-yellow liquid with a characteristic clove aroma and specifies a minimum assay of 98%, with refractive index and specific-gravity requirements.
Eugenol is primarily used in cosmetics for its fragrance, denaturant and tonic functions. Cosmetic ingredient references identify EUGENOL as the INCI name and describe its principal cosmetic functions as fragrance, denaturant and tonic.
Its distinctive clove-like aroma makes it useful in perfumes, deodorants, aftershaves, soaps and other perfumed personal-care products. Eugenol can also contribute to the sensory profile of formulations containing botanical or spice-derived fragrance compositions.
Research literature has investigated Eugenol's antibacterial, antifungal and antioxidant properties. These properties can be relevant when developing specialized formulations, but laboratory antimicrobial activity should not automatically be interpreted as authorization to use Eugenol as a preservative in every cosmetic product.
Eugenol is also recognized as a fragrance allergen in certain regulatory systems. For products marketed in the European Union, applicable fragrance-allergen declaration requirements should therefore be evaluated during formulation and labeling.
Eugenol Cosmetic Ingredient can be used in a broad range of fragrance and personal-care formulations. Its characteristic aromatic profile makes it particularly relevant to perfumes, deodorants, aftershaves, soaps, lotions and other perfumed cosmetic products.
It can also be incorporated into selected skin-care and hair-care formulations where its fragrance and formulation functionality are appropriate. Because Eugenol is oil-compatible and only slightly soluble in water, formulation developers should consider the solvent system and overall composition when developing water-based products.
Eugenol is also widely recognized in oral-care and dental-related applications because of its traditional use and functional properties. However, cosmetic, oral-care and other regulated applications should be treated according to their respective regulatory requirements.
Eugenol is a volatile aromatic liquid, so storage temperature, container compatibility, light exposure and oxidation control should be considered during handling and formulation.
Its limited water solubility means that aqueous cosmetic products may require an appropriate solubilization system. Eugenol can be more readily incorporated into oils and suitable organic solvent systems.
Quality control can include identity, assay, acid value, refractive index, specific gravity, related substances and other product-specific parameters. JECFA specifies a minimum assay of 98%, acid value of not more than 1, refractive index of 1.540–1.542, and specific gravity of 1.064–1.070 for its flavouring specification.
For SEO and technical accuracy, the assay should not automatically be described as HPLC. The applicable analytical method must correspond to the actual product specification and validated test procedure.
Eugenol is an important aromatic specialty raw material for fragrance and personal-care manufacturers. A reliable Eugenol Cosmetic Ingredient Manufacturer in India can provide material with defined identity, purity and physical characteristics for formulation and procurement requirements.
As a Eugenol manufacturer and supplier in India, Swapnroop can support bulk requirements for cosmetic raw materials and specialty ingredients. Product specifications can be selected according to the intended cosmetic application, analytical requirements and customer quality standards.
For commercial manufacturing, consistent control of assay, odor profile, refractive index, specific gravity and other relevant quality parameters helps support reproducible formulation performance.
