Citronellol, identified by its CAS number 106-22-9, is a key chemical compound widely utilized across various industries, most notably in flavors and fragrances. This acyclic monoterpenoid alcohol is characterized by its clear, colorless to pale yellow liquid appearance and its distinct fresh, floral, rosy odor profile.

The chemical identity of Citronellol is C10H20O, with a molecular weight of approximately 156.27 g/mol. It is produced through several synthetic routes, often involving the hydrogenation of geraniol or nerol, or the reduction of citronellal. These production methods ensure a high level of purity, typically 95% or higher, which is crucial for its applications in sensitive areas like perfumery and food flavoring. Its solubility in organic solvents and slight solubility in water influences its formulation behavior.

When considering the applications of Citronellol, its primary uses lie in its aromatic properties. It is a fundamental component in creating rose, muguet, and other floral fragrance compositions. It also finds extensive use in soaps, detergents, and other household cleaning products to impart a clean and pleasant scent. In the flavor industry, it adds subtle citrus and rose notes to various products.

Safety and handling are paramount when working with Citronellol. While generally considered safe for its intended uses when properly formulated, it is known to cause skin irritation and may lead to allergic skin reactions in some individuals. Therefore, adherence to IFRA (International Fragrance Association) standards and proper personal protective equipment (PPE), such as gloves and eye protection, are essential during handling. Proper ventilation in work areas is also recommended to minimize exposure to vapors. Storage should be in tightly sealed containers in a cool, dry, and well-ventilated area, away from heat and ignition sources.

Understanding the chemical properties, production methods, and safety guidelines for Citronellol is crucial for manufacturers and formulators. This knowledge ensures the safe and effective incorporation of this versatile aroma chemical into a wide array of consumer and industrial products.
