hawthorn ethanol
Hawthorn ethanol is a floral fragrance compound characterized by jasmine, lilac, rose, and woody nuances, commonly employed in perfuming agents.
General Material Description
Hawthorn ethanol, also known by its preferred chemical name 3-Methylbenzeneethanol, is a volatile organic compound with the molecular formula C9H12O. It presents as a clear liquid with a characteristic floral odor profile reminiscent of jasmine, lilac, rose, lily of the valley, and woody notes. This compound carries several synonyms, such as 3-methyl phenethyl alcohol and m-methylphenethyl alcohol, reflecting its chemical structure related to substituted benzene ethanols. Hawthorn ethanol is sourced predominantly through synthetic organic methods and is utilized for its sensory attributes in fragrance formulations. For detailed chemical information, it is indexed under the controlled vocabulary entry PubChem CID 74648. Its floral and woody nuances make it valuable in cosmetic perfuming agents.
Occurrence, Applicability & Potential Uses
Hawthorn ethanol is not widely reported as a natural product but is primarily prepared synthetically for use in fragrance compositions. It is recognized under the FEMA (US) standard as a fragrance agent, often contributing jasmine, lilac, rose, and woody notes to perfuming blends. Its application extends mainly to cosmetic and personal care products where a delicate floral aroma is desired. The compound's inclusion in fragrance concentrates leverages its multifunctional odor profile, enhancing the complexity of floral accords in products such as perfumes and scented lotions. Under IFRA (Global) guidelines, the recommended usage in fragrance concentrates may be as high as 50%, although it is not designated for flavor uses.
Physico-Chemical Properties Summary
Hawthorn ethanol is a low-volatility liquid at room temperature, with a boiling range between 240 and 241°C at standard atmospheric pressure (760 mm Hg). It has a moderate estimated logP of approximately 2.06, indicating balanced lipophilicity that aids its solubility in alcohols while showing limited water solubility, estimated at 4399 mg/L at 25°C. The specific gravity ranges between 0.997 and 1.006 at 20–25°C, and its refractive index varies from 1.527 to 1.532 at 20°C, parameters relevant for quality control and formulation calibration. Its estimated flash point of 100°C (212°F) aligns with common organic solvents used in perfumery. These properties contribute to its stability and handling characteristics in fragrance manufacturing and formulation.
FAQ
What is hawthorn ethanol and what are its main characteristics?
Hawthorn ethanol, also known as 3-Methylbenzeneethanol, is a synthetic fragrance compound notable for its floral aroma with jasmine, lilac, rose, lily of the valley, and woody facets. It is utilized extensively in the fragrance industry for its complex scent profile. Chemically, it is an organic molecule composed of nine carbons, twelve hydrogens, and one oxygen atom, with a moderate molecular weight and an aromatic structure substituted by a methyl group.
How is hawthorn ethanol used and where is it typically applied?
This compound is primarily used as a perfuming agent in cosmetics and personal care products. Due to its distinct floral and woody scent notes, formulators incorporate hawthorn ethanol into floral fragrance accords, enhancing products such as perfumes, colognes, and scented lotions. It is not commonly found in natural sources and is typically synthesized for industrial use. Usage levels in fragrance concentrates can reach up to 50% according to IFRA (Global) guidelines, although it is not approved for flavor applications.
What regulations and safety considerations apply to hawthorn ethanol?
Hawthorn ethanol is classified under various regulatory frameworks such as FEMA (US) for fragrance use and adheres to IFRA (Global) guidelines ensuring its safe concentration in consumer products.
