Alcohol C-9

Alcohol C-9 (Nonanol) is a fragrance ingredient used in perfumery for its fresh, fatty, and slightly citrusy character. Its scent profile is typically described as clean, green, and mildly waxy, with subtle nuances reminiscent of orange peel and rose, supported by a soft soapy and oily undertone.

The material usually appears as a clear, colorless liquid with low to moderate viscosity, and is appreciated for its moderate diffusion and smooth, supportive presence in fragrance compositions. Its character is quiet and functional, making it more of a textural and modifying component rather than a dominant note.

Alcohol C-9 is especially valued for its ability to add a natural fatty freshness that enhances the realism and body of citrus and floral accords. It contributes a soft, slightly waxy lift that helps round out sharper top notes and improve overall balance.

In practical perfumery, it is frequently used to support citrus, green, and aldehydic accords, while also adding body and smoothness to floral compositions such as rose and orange blossom. It blends particularly well with citrus materials, aldehydes, floral notes, and green accords, making it suitable for many fragrance styles including fresh compositions, citrus blends, aldehydic perfumes, and clean classic structures.
