Trans-2-Decenal opens with an unmistakable fatty-waxy aldehydic punch that evokes rendered chicken fat at full strength. When diluted to perfumery levels, brilliant orange zest emerges alongside fresh coriander leaf. This powerful material transforms from heavy to luminous through careful dosing. Use this versatile aldehyde to offset the harshness of decanal in classic aldehydic florals while adding photorealistic citrus peel texture. It excels at bridging fatty and fresh-green families, creating depth in orange accords at 20 ppm or authentic cilantro effects at higher levels. The material's exceptional diffusivity provides tremendous top note lift that persists for over eight hours on blotter. Apply sparingly—its potency easily dominates when overdosed, particularly in delicate lemon compositions. In aldehydic florals it modernises classic structures; in green accords it delivers authentic cilantro character alongside other herbal materials. Store chilled.
