Citronellol, a monoterpenoid alcohol with the chemical formula C10H20O and CAS number 106-22-9, is a fundamental ingredient in the flavor and fragrance industry. Its signature scent profile—a blend of fresh, floral, rosy, and sometimes citrusy notes—makes it indispensable for creating appealing aromas in countless consumer goods.

In perfumery, Citronellol is prized for its clean, bright character. It serves as a vital building block for rose accords and fresh floral compositions, adding lift, diffusion, and a sense of naturalness. Perfumers leverage its medium odor strength and versatility to craft fragrances for fine perfumes, soaps, detergents, air fresheners, and many other personal care items. The nuanced scent, often described as reminiscent of geranium or citronella, is a key factor in its widespread adoption.

Beyond its olfactory contributions, Citronellol also plays a role in the flavor industry. It imparts subtle citrus or rose-like nuances to a variety of food products, including candies, beverages, and desserts. Its designation as FEMA GRAS (Generally Recognized As Safe) further solidifies its utility in food applications, ensuring consumer safety and regulatory compliance.

The chemical structure of Citronellol, being an acyclic monoterpenoid alcohol, allows for different stereoisomers, each with a slightly different scent profile. This characteristic provides perfumers and flavorists with a palette of options to achieve specific sensory targets. Understanding the nuances of these isomers, and sourcing high-purity Citronellol, is crucial for achieving desired product outcomes.

The production of Citronellol often involves the hydrogenation of related terpenoids like geraniol or nerol, ensuring a stable and high-quality supply chain. This meticulous chemical synthesis ensures that the ingredient meets the stringent quality standards required by both the fragrance and flavor sectors. Whether you're aiming to create an evocative perfume or a delightful culinary treat, the science of scent and taste points to Citronellol as a key component.
