Description

Citronellal (CAS 106-23-0 ), also identified under FEMA 2307 , is a naturally occurring aldehyde isolated primarily from citronella, eucalyptus, and lemon-scented botanicals. It functions as a key aroma chemical in flavor and fragrance manufacturing, delivering a fresh, citrus-lemon character that forms the backbone of many commercial scent profiles. In fragrance compounding, it is used to build citrus, floral, and green top notes in fine perfumes, household products, and air care formulations for industrial use. Personal care manufacturers incorporate it into soaps, shampoos, and body lotions where a clean, lemon-fresh scent is required for high-quality consumer goods and applications. As a flavor agent, it is used in food and beverage applications including confectionery, baked goods, and citrus-flavored drinks to enhance the overall sensory profile of the product. It also serves as a synthetic intermediate in the production of citronellol, menthol, and other downstream aroma chemicals required for large-scale chemical manufacturing processes. The material is supplied as a clear to pale yellow liquid in drum and IBC quantities suited to industrial fragrance and flavor buyers seeking reliable bulk chemical supply chains. It is available in both natural and synthetic grades, with natural-origin material sourced from citronella or eucalyptus oil commanding a premium for use in natural-positioned formulations.
