methyl sandal
Methyl sandal is a fragrance compound exhibiting medium-strength woody and sandalwood odors, widely used as a fragrance agent.
General Material Description
Methyl sandal is a synthetic fragrance compound classified chemically as 2-Methyl-1-(methylbicyclo[2.2.1]hept-5-en-2-yl)-1-penten-3-ol. It appears as a colorless to pale liquid with a molecular formula of C14H22O and a molecular weight of approximately 206.33 g/mol. Organoleptically, it features a medium-strength woody aroma reminiscent of sandalwood, accented with subtle sweet and autumnal nuances. Among its various synonyms are fleursandol, florasantol, and methyl sandeflor (Takasago). The compound is typically sourced via synthetic organic processes aimed at replicating natural sandalwood scents to meet fragrance formulation needs. The PubChem database provides a structured profile for this material, enabling access to detailed chemical and safety information.
Occurrence, Applicability & Potential Uses
Methyl sandal is a synthetic aroma chemical commonly applied as a fragrance agent in perfumery and personal care products. It contributes woody, amber, balsam, moss, musk, oriental, and sandalwood notes, often lending a waxy character to compositions. This compound does not occur naturally but is designed to mimic the scent attributes characteristic of sandalwood heartwood extracts. Its usage complies with the IFRA (International Fragrance Association, Global) Code of Practice, which recommends maximum concentration limits in fragrance formulations to ensure safe use. Methyl sandal's olfactory profile and substantivity support its use in various complex fragrance accords, especially those seeking a long-lasting woody character.
Physico-Chemical Properties Summary
Methyl sandal exhibits physicochemical characteristics that influence its application in fragrance formulations. It has an estimated octanol-water partition coefficient (logP) of around 3.98, indicating moderate hydrophobicity. The compound's specific gravity ranges narrowly between 0.98 and 0.985 at 20°C, while its refractive index lies between 1.49 and 1.5 at the same temperature, affecting its optical clarity and interaction in blends. Boiling points reported are approximately 295 to 296°C at atmospheric pressure, with a lower boiling range at reduced pressure (80 to 81°C at 1 mm Hg). Vapor pressure is low (around 0.000157 mmHg at 25°C), contributing to its substantivity in fragrances. It is soluble in alcohol and dipropylene glycol but shows limited water solubility, estimated at about 19.63 mg/L at 25°C. These properties support its stability and potency in typical perfume carrier systems.
FAQ
What is methyl sandal and what are its key characteristics?
Methyl sandal is a synthetic fragrance ingredient chemically described as 2-Methyl-1-(methylbicyclo[2.2.1]hept-5-en-2-yl)-1-penten-3-ol. It possesses a medium-strength woody odor with sandalwood nuances, often described as sweet and reminiscent of autumn sawdust. The compound appears as a pale liquid and is used primarily for its aromatic properties in fragrance formulations.
In what types of products and formulations is methyl sandal typically used?
Methyl sandal is mainly utilized as a fragrance agent in perfumes and personal care products, contributing woody, amber, balsam, moss, musk, oriental, and specifically sandalwood notes. It is preferred for its long-lasting odor profile and medium substantivity, which allows it to provide depth and persistence in complex fragrance blends.
How is methyl sandal regulated, and where can it be sourced safely?
Methyl sandal’s use in fragrances is regulated under the IFRA (Global) Code of Practice, which sets recommended maximum usage levels to maintain consumer safety, typically up to 5% in fragrance concentrates. It is not approved for flavor use. Suppliers such as Takasago provide methyl sandal under controlled standards, and safety data are available from resources like the RIFM Fragrance Material Safety Assessment and regulatory databases including EPA TSCA and EPI System.
