Aldehyde C-11 Undecylenic (10-undecenal, CAS# 112-45-8) is a long-chain aliphatic aldehyde with a sharp, highly diffusive aldehydic character that instantly “switches on” the top of a fragrance. Its odour profile combines zesty citrus-peel facets with a green, slightly metallic nuance, a light fatty–waxy feel and a clean, soft floral impression reminiscent of sun-dried, freshly laundered linens. At very low levels, it creates a refined “premium soap” effect and a sense of airy cleanliness, making any composition feel brighter and more contemporary.
In perfumery, Aldehyde C-11 Undecylenic is a key material for aldehydic, citrus, soapy and “clean linen” accords. It pairs particularly well with orange, lemon, bergamot, petitgrain, galbanum, muguet, rose, jasmine and ozonic–marine notes, helping to build sparkling, luminous top notes with strong diffusion. Just a small amount can extend the freshness of citrus accords and boost the overall brilliance and lift of the formula.
Because of its high intensity and powerful diffusion, Aldehyde C-11 Undecylenic is usually used at low dosage (trace to very low levels) in fine fragrances, body mists, soaps, detergents, fabric softeners, floor cleaners and other home care products where a long-lasting clean–fresh effect is desired. It is especially useful when a clear aldehydic signature is needed, evoking classic aldehydic florals while keeping the overall character airy and modern.
For the perfumer, this is a material that demands respect in terms of dosage: if overdosed, Aldehyde C-11 Undecylenic can easily become harsh, metallic and dominating. Used with a careful hand, it acts as a “light source” in the composition – bringing life, professional polish and a finished feel to citrus–floral, soapy, fresh linen and classic aldehydic themes.
