Nootkatone is a natural organic compound found in grapefruit. It is responsible for the characteristic citrus scent of grapefruit, providing a fresh, crisp, and sweet citrus aroma. Nootkatone is highly valued in perfumery for its vibrant, energizing grapefruit scent that enhances citrus and fresh fragrance formulations.
Predominantly used to replicate or enhance the grapefruit scent in perfumes and colognes. Its refreshing, zesty quality makes it a popular choice for summer fragrances, sporty scents, and unisex perfumes aiming for a lively, citrusy profile.
