1,4-cineole

1,4-Cineole (CAS 470-67-7), also known by its FEMA 3658 designation, is a naturally occurring bicyclic ether found in various essential oils and used commercially as a flavoring and fragrance ingredient. Unlike its more abundant isomer 1,8-cineole, this compound offers a distinct, milder eucalyptus-like profile that positions it as a differentiated raw material for flavor and fragrance houses.

In food and beverage flavoring, 1,4-Cineole contributes subtle herbal and cooling nuances to confectionery, chewing gum, and mint-forward flavor systems where a softer aromatic character is preferred. Fragrance formulators incorporate it into personal care products, including shampoos, body washes, and topical cosmetics, to achieve fresh, green, or spa-like scent profiles for high-end consumer goods.

It also functions as a supporting ingredient in oral care formulations such as mouthwashes and toothpastes, where its aromatic character complements menthol-based systems for a balanced sensory experience. 1,4-Cineole is supplied as a colorless liquid, typically in quantities ranging from small sample lots to bulk drums suited for industrial-scale flavor and fragrance production and distribution.

It is available in flavor-grade quality consistent with FEMA-recognized use, and buyers should confirm purity specifications and isomeric composition with the supplier prior to sourcing the material.
