Overview
γ-Muurolene is a naturally occurring sesquiterpene hydrocarbon found in the essential oils of various plants, including chamomile, hops, and certain conifers. It is valued for its woody, earthy aroma, making it a popular ingredient in perfumery and flavorings. As a volatile compound, it contributes to the complexity of essential oil blends and is often used in aromatherapy for its calming properties. In industrial applications, γ-Muurolene is synthesized or extracted for use in high-end fragrances and food flavorings. Its stability and compatibility with other aromatic compounds make it a versatile component in formulations requiring long-lasting scents.
Physical and Chemical Properties
γ-Muurolene is a colorless to pale yellow liquid with a characteristic woody and slightly spicy odor. Its molecular structure consists of three isoprene units, typical of sesquiterpenes, contributing to its relatively high boiling point and low water solubility. The compound is stable under normal conditions but may degrade when exposed to strong oxidizers or prolonged heat. Its density ranges between 0.89 and 0.91 g/cm³, and it is soluble in common organic solvents such as ethanol, ether, and chloroform. These properties make it suitable for incorporation into alcohol-based perfumes and oil-based flavorings.
Main Applications
The primary use of γ-Muurolene is in the fragrance industry, where it serves as a middle or base note in perfumes, providing depth and longevity to scents. It is also employed in food flavorings, particularly in products requiring earthy or herbal undertones, such as certain beers and herbal teas. In aromatherapy, γ-Muurolene is valued for its potential relaxing effects. It is often blended with other terpenes to enhance therapeutic formulations. Additionally, research explores its role as a precursor in the synthesis of more complex fragrance molecules.
Safety and Storage
γ-Muurolene is generally considered safe when used in approved concentrations for fragrances and flavorings. However, direct skin contact or inhalation of concentrated vapors should be avoided to prevent irritation. Proper ventilation is recommended when handling the compound in industrial settings. Storage conditions are critical to maintaining its stability. It should be kept in tightly sealed containers, away from heat sources and open flames, due to its flammable nature. Suppliers often recommend storing it at temperatures below 25°C in a dark, dry environment to prevent degradation.
B2B Procurement Guide
When sourcing γ-Muurolene for commercial use, buyers should prioritize suppliers with certifications for fragrance or food-grade applications, depending on the intended use. Key factors to evaluate include purity (typically 95% or higher), batch consistency, and compliance with regulatory standards such as IFRA or FDA guidelines. Price varies based on purity, volume, and supplier reputation. Bulk purchases may offer cost advantages, but sample testing is advisable to ensure quality. Procurement professionals should also verify the supplier's ability to provide technical data sheets and safety documentation.
