Aldehyde C-10 (decanal)

Aldehyde C-10 (Decanal) is a classic fragrance ingredient valued in perfumery for its fresh, citrusy, and slightly waxy character. Its scent profile is typically described as bright, smooth, and slightly sweet, reminiscent of orange peel and citrus oils, with a subtle soapy and fatty nuance that adds elegance and body.

The material usually appears as a clear, colorless liquid with low viscosity, and is appreciated for its good diffusion and well-balanced aldehydic presence. Its character is less sharp than shorter-chain aldehydes, offering a more rounded and refined freshness.

Aldehyde C-10 is especially valued for its ability to provide a natural citrus lift with a soft aldehydic texture, making it an important bridge between citrus and aldehydic accords. It contributes a clean, slightly waxy brightness that enhances the smoothness of a composition.

In practical perfumery, it is frequently used to build citrus, aldehydic, and fresh accords, while also adding lift and elegance to floral compositions such as rose, jasmine, and orange blossom. It blends particularly well with orange, bergamot, lemon, other aldehydes, floral materials, and musks, making it suitable for many fragrance styles including citrus colognes, aldehydic florals, clean compositions, and modern fresh perfumes.
