Aldehyde C-6 FCC (Hexanal)

Aldehyde C-6 (Hexanal, FCC) is a distinctive fragrance ingredient valued in perfumery for its intensely fresh, green, and sharply natural character. Its scent profile is typically described as crisp, leafy, and slightly fatty, strongly reminiscent of freshly cut grass, crushed leaves, and green plant stems, with a subtle apple-like nuance that adds a natural fruity freshness.

The material usually appears as a clear, colorless liquid with low viscosity, and is appreciated for its very high volatility and immediate impact. Its character is sharp, vivid, and highly diffusive, making it particularly effective for creating a realistic green top note.

Aldehyde C-6 is especially valued for its ability to deliver a true-to-nature “green” effect, often used to recreate the smell of cut grass or freshly broken plant tissue. This makes it one of the key building blocks in green and natural-style fragrance compositions.

In practical perfumery, it is frequently used to build green, leafy, and herbal accords, while also adding freshness and lift to fruity compositions (especially apple notes) and citrus blends. It blends particularly well with green notes, cis-3-hexenol derivatives, citrus materials, herbal notes, and light florals, making it suitable for many fragrance styles including green fragrances, fresh natural compositions, fruity accords, and functional products.
