Description

Nootkatone 98% is a high-purity sesquiterpene ketone renowned for its distinctive grapefruit character. Its odor profile combines fresh, bitter citrus nuances with woody, earthy and slightly green facets, creating a realistic grapefruit-peel impression. Unlike many bright citrus materials, Nootkatone has a deeper and more persistent character that remains noticeable well into the drydown.

In perfumery, Nootkatone is primarily used as a high-impact citrus and grapefruit modifier. It can give citrus accords greater realism and bitterness while adding depth and longevity. It is particularly effective in grapefruit, citrus, fresh woody, green and aromatic compositions, where a small quantity can dramatically change the character of an accord.

The 98% grade indicates a highly concentrated material, making it particularly useful when precise dosing and strong olfactory impact are required. Because Nootkatone is powerful, careful evaluation at low concentrations is recommended before increasing the dosage.

Perfumers' Tip

Nootkatone is best treated as a high-impact grapefruit character material. Use it with grapefruit oil to reinforce natural peel-like bitterness, or combine it with lemon, bergamot and lime for a sparkling citrus accord with greater depth. A trace can be enough to make a citrus composition feel noticeably more realistic and persistent.
