Overview
Guaiacene, commonly referred to as guaiene, is a sesquiterpene compound naturally found in guaiac wood oil and other botanical sources. It is prized for its distinctive woody and spicy aroma, making it a popular ingredient in perfumery and aromatherapy. The compound is synthesized through steam distillation of guaiac wood or extracted from other natural sources. Its unique fragrance profile has led to widespread use in high-end perfumes, soaps, and cosmetic products, where it serves as a base note to enhance longevity and depth.
Physical and Chemical Properties
Guaiacene is a colorless to pale yellow liquid with a molecular formula of C15H24 and a molecular weight of 204.36 g/mol. It is insoluble in water but readily dissolves in alcohol and essential oils, which makes it suitable for blending in fragrance formulations. The compound exhibits stability under normal storage conditions but should be protected from prolonged exposure to light and heat to prevent degradation. Its boiling point ranges between 265-270°C, and it has a density of approximately 0.915-0.925 g/cm³, typical for sesquiterpenes.
Main Applications
The primary use of guaiacene is in the fragrance industry, where it contributes to woody and spicy scent profiles. It is often employed as a base note in perfumes, colognes, and scented candles, providing depth and warmth to compositions. Beyond perfumery, guaiacene is utilized in aromatherapy for its calming and grounding effects. It is also occasionally used as a flavoring agent in food and beverages, though this application is less common due to regulatory restrictions in some regions.
Safety and Storage
Guaiacene is generally considered safe for use in cosmetics and fragrances at recommended concentrations. However, undiluted forms may cause skin irritation, so proper handling and dilution are advised. For storage, guaiacene should be kept in tightly sealed containers in a cool, dry place away from direct sunlight. Proper storage conditions help maintain its stability and extend its shelf life, which is typically 1-2 years when stored correctly.
B2B Procurement Guide
When procuring guaiacene, B2B buyers should prioritize suppliers who provide certificates of analysis (CoA) to verify purity and authenticity. Bulk purchases often come with cost advantages, but buyers should ensure that storage facilities can maintain optimal conditions. It is also advisable to sample small quantities before committing to large orders, as the quality of natural extracts can vary. Reputable suppliers often offer technical support and documentation to assist with regulatory compliance, particularly for international shipments.
