Cedroxyde® (Firmenich)

Description

A potent and elegant woody character emanates from this versatile aromatic material, presenting a multifaceted profile with a strong ambergris tonality. Its scent is predominantly dry and cedar-like, reminiscent of sharpened pencils, yet it unfolds with a subtle sweetness and a sophisticated powdery facet. Derived from cedrene, the primary component of cedarwood oil, this woody epoxide known as Cedroxyde® possesses a refined complexity that includes nuances of sandalwood and clean patchouli. The resulting profile is a modern, tenacious, and highly diffusive woody amber note that provides both foundation and lift to a composition.

In application, its exceptional substantivity and power make it a valuable tool across fine fragrance and consumer products. It performs as a superb fixative and booster, lending volume and a persistent warm, dry-woody effect that is particularly noticeable on fabrics. Recommended usage levels vary widely depending on the desired effect, from a mere trace to enhance the naturalness of cedarwood accords, to higher concentrations where its distinct amber character can be a central theme. Cedroxyde® combines seamlessly with other woody notes, ionones, florals, and modern musks, serving as an effective and cost-efficient alternative or companion to materials like Ambroxan.
