Aldehyde C-18 COCONUT

Aldehyde C-18 (Coconut) — more precisely known as γ-Nonalactone — is a key fragrance ingredient valued in perfumery for its creamy, milky, and distinctly coconut-like character. Its scent profile is typically described as sweet, smooth, and lactonic, strongly reminiscent of fresh coconut, coconut milk, and tropical desserts, with a soft buttery and slightly peach-like undertone.

The material usually appears as a clear to pale liquid with moderate viscosity, and is appreciated for its rich, diffusive presence and excellent substantivity. Its character is creamy and enveloping, making it particularly effective for adding a smooth, gourmand texture to fragrance compositions.

Aldehyde C-18 is especially valued for its ability to create a natural coconut effect with depth and softness, forming the backbone of many tropical, solar, and gourmand accords. It brings a sun-kissed, creamy warmth that enhances both sweetness and roundness in a formula.

In practical perfumery, it is frequently used to build coconut and tropical accords, while also adding creaminess and body to fruity, floral, and gourmand compositions. It blends particularly well with vanilla, lactones, fruity notes (especially peach and pineapple), white florals, and musks, making it suitable for many fragrance styles including tropical fragrances, solar perfumes, gourmand compositions, and creamy floral blends.
