Natural Aldehyde C-7 (Heptanal) is a luminous aliphatic aldehyde valued in perfumery for its fresh, fatty-green, citrusy, and slightly fruity character. Naturally occurring in trace amounts in various botanical sources, it brings a clean yet sensual brightness that bridges citrus freshness and creamy warmth. Its scent profile recalls green citrus peel, waxy lemon, soft tropical fruit, and fresh aldehydic air, making it an essential tool for perfumers seeking radiance and diffusion.
In compositions, Aldehyde C-7 is widely used to energize top notes, enhance lift, and create a polished opening. It adds sparkle to citrus accords, elegance to florals, and smooth roundness to creamy and lactonic structures. When used judiciously, it softens sharp edges while contributing a modern, slightly fatty nuance that feels both natural and sophisticated.
This aldehyde is especially effective in citrus florals, aldehydic bouquets, fruity accords, modern musks, and gourmand-leaning compositions. In natural and niche perfumery, Aldehyde C-7 offers clarity, diffusion, and refinement, helping fragrances feel alive, expansive, and beautifully balanced.
